Note, mathematics is for the elite. Football is for the infantry !
I hate football. You are right here .

I just verified the certificate for [TEX]2^{22464}+63691[/TEX] generated by engracio, so this is now a proven prime. The verification took 29 hours, 7 minutes, and 29 seconds on an Athlon XP 1400 MHz chip, fast considering how long it took him to generate it! Interestingly enough, the other verification of [TEX]2^{21954}+77899[/TEX] (see post #36) took 28 hours, 45 minutes, and 47 seconds on a faster 3000 MHz Pentium D processor. I've been aware that Primo seems to run particularly well on AMD chips, I wonder if this extends to 64-bit processors.

We now have 28 remaining probable primes, in addition to the 3 sequences for which we are still searching for a probable prime. Way to go, Engracio!
:bow wave::bow wave::bow wave:

Dear members, in 3-4 weeks ( so I hope ) the certificate is available.
Based on the actual stand.

Stand : Day 58 , Phase 1 TEST 281 21876/29728 : Phase 2 TEST 260

..

Normi

You don't believe it, in few days (10?) , the certificate of "2^29727+ 20273" is maybe available....time total: about 80 days

[quote=Cybertronic;181767]You don't believe it, in few days (10?) , the certificate of "2^29727+ 20273" is maybe available....time total: about 80 days[/quote]

Normi,

When you get that certificate and Phil validates the certificate, you my friend will have to break down and try to make a SIMPLE howto on your system for people like me that has black string on my left hand and white string on my righ hand.:shock: What's my name again???

Maybe the next few prime will be done sooner.:smile:

[quote=engracio;181772]

When you get that certificate and Phil validates the certificate, [/quote]

The last step is the validation by me (takes about 24-30h) , because the *.out-file have for now a invalid signature.

Also it is possible to create a TEAM worldwide for one certification.

2^26795 + 57083
 

My certification is slowly pacing on.

I'm actually at Phase 1, test 217, run 1, bits 21058/26796

The good news: it seems that I'm going faster and faster through the test :smile:

Luigi

..more , when ready on Monday or Tuesday :smile:

My proof of 2^24910+62029 completed about 2 days ago. Phil, what file(s) do you need and where should I send it/them?

It took about 15-20 days longer than expected. I did have 2 power outages while running the proof but I kept it backed up once/day and reverted back to the prior day's backup each time.

I have to admit I have no desire to do such a long proof again but it was fun to prove a big one and I learned some things about the software and timings. :-) I will be curious to see how high people will continue reserving these here.


Gary

Thanks, Gary. Anyone can run a verification on the certificate, so it is fine if Norman wants to run his. However, I would enjoy verifying it as well, also to see how certification with Cert_Val compares with that of Primo. The file you need to send me is the .out file from your work folder. Norman, I would appreciate a copy of your .out file as well, before you run the verification. You can email me at moorep at lanecc period edu.

I am leaving on vacation on Saturday for a couple of weeks, so I will presume that Gary's verification will go smoothly and update this thread. Congratulations, Gary! Looking forward to hearing of Norman's results soon...

[quote=philmoore;182415] I would appreciate a copy of your .out file as well, before you run the verification. You can email me at moorep at lanecc period edu.[/quote]

Sorry, the verification is the LAST step of my methode. There are not exist an .out-file, just an .tmp-file.

I have to do rename the tmp-file to out and then I start the verification.

Now I'm on TEST 536 ( 14941/29792 ). The next 2 days is a full time job, by my hands.

But you get a copy from the valid ( so I hope ) certification.

Also I have a nice downrun-table :smile:

DOWNRUN-Table
Date......... Phase 1 Digits..Phase 2
................at Test .left ...Tests done
05/10/2009 001 ..... 8949
05/25/2009 050...... 8455. 037
06/05/2009 100...... 7988. 083
06/18/2009 150 ......7555. 129
06/25/2009 200 ......7166. 175
07/05/2009 250 ......6830. 239
....




Norman

Then the .temp is what I would need to test whether Cert_Val can also do the verification. If you can't send that (maybe you have a script that starts the verification automatically), I will see if Cert_Val can work from the completed verified certificate.

Phil

Phil, I have Emailed you the certification.

Good news , principled the certificate is done. ( at the moment with
an invalid signature )
The validation is running. I believe it takes 28h.

Number of tests : only 1127
Running time : 1880 h

I cross my fingers ! :smile:

Yeah ! It's done. 2^29727+20273 is PRIME !!!

Lol, I'm on TEST 2

Here an exitation

[url]http://www.sendspace.com/file/j7y0dk[/url]

Norman, I have a suggestion:

Write up a detailed description of your method in German, and we will translate it so others may try it. I know enough German to do a rough translation, and we have several German users of this forum that I'm sure would be willing to help. You could post your description, or send it to me, and we will post the translation. It would be exciting to do several more of these numbers!

Phil

Okay Phil, I will write in an easy german, but is it a problem to mention me namently ... as second name ?

I will just paste the translation into one of your posts so everyone knows that you developed the method. If you wish, you could post in the thread [B]Primo 3.0.7[/B] as a sort of user's guide for advanced users.

2^33548+4471 with PRIMO
 

First Report:

After 8 days :
I'm on TEST 24 (32995/33549). ( 9933 digits ) :groupwave:
So Phase 1 need only 110-120 days.
I hope it's done before 2010.

It is very cumbersome and sluggish.

Now I'm on TEST 56 31898/33548 Phase 1 and TEST 44 Phase 2.

Elapsed time: 23 days.:sick:

Update
 

Phase 1, Test 269, Run 1, Bits 19774/26796.

I catched up with my last backup failure. Things are getting faster now. :smile:

Luigi

Luigi, good luck ! :rolleyes:
....
Stand: Phase 1 TEST 85 (30940/33549): Phase 2 TEST 1-82 done

anyone fancy reserving the new one:smile:

Gary (gd_barnes): I had forgotten that I had not verified the certificate you sent me while I was on vacation, but I just finished verifying it, and will forward it on to Marcel Martin. Nice work!

Hello, downrun sequenz of "2^33548+4471" have reached the actual PRIMO record. I will more optimize my methode and I think this certificate is done between 20th and 25th nov. 09.[U]

Does anybody have any update on this? I tried the online translator and it is not so good.

I started a translation when I was on vacation, but never got back to it once I got distracted by the new prp. I'll take another look at it, post a rough translation, and ask any knowledgeable German speakers to suggest revisions. Thanks for the reminder.

PRIMO on a Multicore
 

Here is my actual excel-table.
Maybe you can understand, how it works.

Wow! I stand corrected normi. After typing this post, I checked the test again and it has jumped to test 930 and climbing steadily. I think the proggie is just cleaning up and ready to finish phase 1. W00T:grin:

If you have guts to split your tmp-file into 4 tasks (on your 2.6 GHz Phenom X4), you will done next weekend.

Should you split for Phase 2 then :

Core1 make TEST 1-50
Core2 51-150
Core3 151-399
Core4 400-1027

The signification need 1 day

So the certification is 3-4 weeks earlier done.

Good news. The downrun of the first 10000 bits are done. So 7060 digits left and this are peanuts. In 4-5 weeks I also done with this huge number.

Very cool, Luigi! By coincidence, Engracio just sent me the file for 2^25563+22193 which also completed its certification this week, and I am running the verification on it at the moment. It should finish today, and I can do yours next. What I need is the big OUT file, it is probably over 3 Mbytes in size. You can verify it yourself, but if you want me to do it, I would be happy to. moorep lanecc edu with at and dot inserted is my email address. Norman's monster will be the next to complete...

"Norman's monster will be the next to complete..."

Oh yes Phil :smile:.

Maybe next weekend. I'm now at 16500 bits (TEST 598).
Also runs the verification during Phase1 and 2.
So I need not wait once more 48 h for a valid certificate, e.g.
Phase 1 , Phase 2 and the verification is done on the same day.

Of course, when Norman's current prime finishes, and gets listed at 7th (assuming nothing larger is proven in the meantime) these two will be pushed down a notch.

I believe , my is a little bit larger :smile:

Since Juli 2008 he run PRIMO on a single task. It is a race between 2 huge PRPs, but Friday this week I'm done .


Theoretical, I can prove 2^38090+47269 in 180 days, but not yet.

Yeah, you don't believe it !!!!!!!

The monster number is now proven prime !

119 days! That is fantastic, but of course it required a lot of work from you in addition to computer time. Congratulations, Norman!

Nice job Norman! :smile:

Now I'll be on the last place of Caldwell's database...

Luigi

Maybe, the number "2^38090+47269" we can't certify with PRIMO.
Now I'm on RUN 6 delta=-45000.
:ermm:

Norman I've decided to try your method and I just need to clarify a few things.

I am on Test 228 and have copied all the files to folders Primo1, Primo2, Primo3. I change the *.temp file and ar=1 for run 1, ar=2 for run 2 and ar=3 for run 3. I also change ap=1 for each run if I wanted to start from index 1.

When one of the run completes to the next test, here it would be Test 229. I would then stop all other run and copy the *.temp to folder Primo1 to start run1 on Test 229, run 2 on folder 2 and run 3 on folder 3. Is that good so far???

When one of the run completes to the next test, here it would be Test 229. I would then stop all other run and copy the *.temp to folder Primo1 to start run1 on Test 229, run 2 on folder 2 and run 3 on folder 3. Is that good so far???[/quote]

Yes Engracio.
But also using a Editor ,like Excel, and memorize from TEST 228 the 3 index numbers of RUN 1,2,3, because you find easier the latest position for a manual backtracking.
Save the new tmp file in another directory like "C:\back\" and copy *.tmp to *.228_18791(bit) or so, if TEST 229 a failure.

When you download the record certificate (10099ecpp.zip) then you get my logbook in ecxel. I think this is very useful.

[B]What is the purpose of saving the index and how? How do I save the index? Is it after one of the runs i.e. run 3 found the next test, do I save the index of run 1 and run 2 before stopping it and going to the next test found by run 3???[/B]

[B]I do that now, make sense, it will let me go back to a known test in case the new one is a dead end.[/B]

[B]What is a delta? Also I tried to use one of the core to run Phase 2 but it seems to just set there. When I took off the " - " on test 1, it jumped to test 2 bypassing test 1.[/B]

[/quote]

[B]^^^^^^^[/B]

[B]Thanks.[/B]:smile:

[B]What is the purpose of saving the index and how?

Example:
You jump from TEST 228 RUN 3 index=2901 to TEST 229...
and this TEST 229 is a dead end (avoid RUN6 , it takes to many time in Phase 2) ..then you can go directly to TEST 228 RUN1 index=latest stand. PRIMO start automatic a backtrack and go to TEST 228 RUN3 index=2903.

How do I save the index?
In a table per hand.

Is it after one of the runs i.e. run 3 found the next test, do I save the index of run 1 and run 2 before stopping it and going to the next test found by run 3???[/B]

Yes.

[B]What is a delta?
PRIMO call it index for RUN 1..5, for RUN 6 is it delta


Also I tried to use one of the core to run Phase 2 but it seems to just set there. When I took off the " - " on test 1, it jumped to test 2 bypassing test 1.

Edit the nearest newest tmp-file and set "pe=2" and take off all "-"
of your done TESTs in Phase 2. Copy the new ready point ,like [3],[4]...[10]... in a advance certificate. Attach it in logical order.
Kill in every ready TEST in Phase 2 "sf=" and "pm="

In your case, you set only pe=2. PRIMO can calculate the first 228 TEST..and it takes a while.


[/B]

So Norman, as long as the certification is moving from one test to another then it is working correct??

Well test 229 have to run (6) delta.:cry: Run 1..3 just jumped to the next run. I saved the index on excel for run 4 (index 195984)and run 5 (index 36479).

Now for Phase 2. With the most current *.temp test 229, all I have to do is change pe=1 to pe=2 and let it run? It will eventually move from test 1 to test 2???

Do I need any of the other files to run Phase 2 or just the *.temp file???

[quote=engracio;197926]So Norman, as long as the certification is moving from one test to another then it is working correct??

YES !

Well test 229 have to run (6) delta.:cry: Run 1..3 just jumped to the next run. I saved the index on excel for run 4 (index 195984)and run 5 (index 36479).

Oh ! RUN 6 is bad, but it is okay.

When you look up to the end of the tmp file , in your case "TEST 228"
then you will see, where PRIMO found the parameters for TEST 229.
It is rn=6 ( the RUN ) and pm=*** ( that is the index number +2, for backtracking ). Theoretical you can notice rn and pm in TEST[228] Phase 1 and delete complete in the tmp-file TEST 228. Set "TestCount=227" and
set to begin ar=rn of 228 amd ap=pm of 228 , ar=rn+1 and ap=1 for core 2 and so on. Make a secure copy of the old tmp-file. Also you can try
another point with rn=4 and rn=5 with the TEST 228 tmp-file. There are good chances.

Now for Phase 2.
With the most current *.temp test 229, all I have to do is change pe=1 to pe=2 and let it run?

YES !


It will eventually move from test 1 to test 2???

PRIMO start with Phase 2 on TEST 1

Do I need any of the other files to run Phase 2 or just the *.temp file???

No, just the tmp-file you need.

....

Okay Norman you are right, I changed pe=1 to pe=2 to run Phase 2 and just let it run. Now after 18 hours it is on test 3.:smile:

Now the big question. Test 229 moved to Test 330 by running run 6 or delta. I decided to just continue what I was doing for Test 330 and started running run1..4 where all 4 completed and moved to the next run. I am now on run 5 and run 6 and both are still running after 19 hours. Question is if run 5 moves to the next test Test 331, is it okay to continue normally? If run 6 or delta moves to Test 331, what do I do? After 19 hours is it okay to continue and let the test run or should I go back to a previous test like test 227 or 228?

I don't understand. TEST 230 or 330 ?
Have you edit the primo.ini and add
[Setup+]
MSC=26
?
With MSC=26 you have much more possibilities to finished a TEST.
Avoid RUN 6 ! It takes to many times in Phase 1 and 2.
Is RUN 1 2,3 done then start RUN 4 , 5 and a previous way , like TEST 229 , RUN 1 or 2 or 3 ( a RUN which is not done ) ,index = latest stand of the RUN which not done.


"Question is if run 5 moves to the next test Test 331, is it okay to continue normally?"

Yes, you start TEST 331 with RUN = 1,2,3...
Note, prior you can test a TEST , whether PRIMO start automatic RUN 2 or 3, So you can start with RUN 1 and 3, 4. 2 is most automatic.

"If run 6 or delta moves to Test 331, what do I do? After 19 hours is it okay to continue and let the test run or should I go back to a previous test like test 227 or 228?"

You go back, is RUN 1,2,3,4 and 5 a dead run. For <20000 bit numbers is
every 30th TEST a dead run.

I'm glad of your decision :smile: !

Ooops typo error.:smile: This is what I type in "Setup+]
MSC=20..26 ". I suppose it should have been MSC=26, changing it now.:sick:

Okay Test 229 have run 4 and run 5 not completed. I will backtrack to those 2 runs and hopefully it finds another path to the next test.

I will also continue to run 5 test 230 hoping it also moves to the next test.

Okay, so you can building slow the final certificate. You can copy the first 2 TEST and delete the sf= and pm=

Copy your tmp-file to an out file.

You must remember I am on just moving from test to test right now.:smile: One step at a time unless it is necessary to prevent problems 2 months later.:grin:

And you know what you are doing.:geek:

Okay Test 230 run 5 is still running index 119340. Test 229 run 4 and run 5 are running again picking up from the index recorded on my excel.

I hope one of the runs find the path to the next test.

I mean it is a little training:smile:. The first 2 TESTs of Phase 2 are done, so you have a tiny part of the certification now.

You should append all TESTs of Phase 2 in the finally file. The finally file you get, when you copy the actual tmp-file to *.out.
Delete all lines from [X] to the end of file.
Insert the done TESTs of Phase 2 after "BinarySize=" line in logical order.

A hint: It is very useful to save all *.s** files of RUN 1,2,3,....
Is PRIMO on TEST 230 , you find *.s230.
Go PRIMO on TEST 230 , RUN 1, index = 2301 to TEST 231 , then you can copy *.s230 to a seperat directory , like :\run_s\ *.230_bit_r1.

Have PRIMO the *.s file, so can PRIMO finished faster this RUN.
In the *.s file are informations about the optimal index selection.
If you lose *.s-file , so PRIMO takes more time to finished a RUN.

Okay I have just started saving *.s from test 228 so from now on I will save them too. Thanks.

edit:

btw Norman, when I tried to open the *.s files it just show some non readable junk. Can I open the file or not??

You can open it, but you get letter salad :smile:.
It is not a txt-file

Okay so nothing to see on the *.s file. Thanks I just thought I was doing something wrong.

A hint for the Phase 2 procedure.

Before you append the next done TESTs of Phase 2, compare the last

S$=*** of [XYZ] in your certificate with your actual tmp-file at TEST [XYZ].

Is it not equal , so is the done TEST of Phase 2 invalid. It is the case
if you chosen another way. I mean TEST [XYZ] of Phase 2 is valid, but you have depraved this point during Phase 1 through a backtrack.

Okay Test 229 have run 4 and run 5 not completed. I will backtrack to those 2 runs and hopefully it finds another path to the next test.

[B]Norman saving the index for Test 229 run 4 and run 5 enabled the test to move on now at Test 335. The other run 5 on Test 330 was a dead end.[/B]

I will also continue to run 5 test 230 hoping it also moves to the next test. [B]Dead end[/B] :sad:[/quote]

^^^

You mean , you are now at [B]TEST 235[/B] ? TEST 230 RUN 4 was the only way ?
Do you believe , it is now faster ? IF you now at TEST 235 then I think you are in few days (1-2) at TEST 260.

Yes definitely faster than the last two days. It even completed test 232 and test 234 while I was not around.:smile: Both were run 1 completion.

Talking about Phase 2 I am now on test 6 maybe even on test 7 now. What do you mean by append to the file or even better yet give an example on how to start the merging of phase 1 and phase 2 files. Can you try to merge the two phase before either phase is completed??

[quote=engracio;198120] What do you mean by append to the file or even better yet give an example on how to start the merging of phase 1 and phase 2 files. Can you try to merge the two phase before either phase is completed??[/quote]

Procedure:
----------

1. create an out file , look like #174
2. in your case : copy alle done TESTs [1]..[(228 , S$= the same)] of Phase 2 into your out file. Delete sf= and pm= in each TEST :-(

3. yet you need [229 , 230,...] : After copying you overwrite the tmp file with the newest tmp file and set pe=2. Take off "-" from [1]..[228] and start PRIMO. PRIMO jump to TEST 229 Phase 2. I use the old Norton Comander 2.0 for Windows. Its easy to kill automatic all "-" of Type=-***
After this you rewrite with NC 2.0 from [229] to EOF "Type=-"

4. If you have any new done TESTs of Phase 2, you append it in the out-file. But compare the last S$= TEST of out-file with the newest tmp-file)

Big surprise ! I'm on TEST 2 :smile:
At TEST 1 RUN 6 delta = -14 M

Maybe it is possible to certify "2^38090+47269"

Good news, I will extended my PRIMO record and I take the number "2^38090+47269" :smile:

Now I'm on TEST 4 , 38029/38091.

Good job Norman. You'll probably finish before I do.:smile: I got stuck on a few test and just broke out of it to test 260. I ran into test 257 and almost completed all 5 runs and ending up backtracking to test 256 twice. Each time it backtracked and found the next test it was a different bit. Finally found the good test and moved thru test 258.:grin:

[quote=engracio;198721] Finally found the good test and moved thru test 258.:grin:[/quote]


Sounds good ! I believe , you are now on 19900 bit. 5 days ago on 20600 bits. Save all ways and take ever the way with the lowest bit.
Well done !

Norman I am moving along and on Test 303/19010bit. My phase 2 test is on test 22 also moving along.

I think I got the Phase 1 rhythm of saving the new test/*.tmp to backup, over writing the old *.tmp with the new test *.tmp and running run 1..5. Luckily I have not done any Run 6/delta. Run 1..5 have always managed to jump to the next test or I was able to go back to a previous test and move up to the next test from there.:smile: Now it is just waiting for the 950 odd phase 1 test to complete.

Question on phase 2, my current *.tmp running phase 1 is only up to test 229. As I stated I am now on test 303. What is the best way to multi task phase 2 if I have another core??

Should I copy/append test 230 to the end of test 229 or on a different folder with a different core start phase 2 on test 230???

Which is better, delete test 1..229 or take out [B]Type=-4 [/B]up to test 229and run pe=2/phase 2?

I know you said we need to copy all of the completed/ready test to a pre-certificate file prior to merging all files and running the certification. Thanks.:smile:

Multicore Phase 2
 

[quote=engracio;199387]
Which is better, delete test 1..229 or take out [B]Type=-4 [/B]up to test 229and run pe=2/phase 2?

BTW , there are 4 Types :smile:.

[/quote]

No! You can't delete any TESTs ! So you will destroy the certificate.

Create for each core a new directory, like Phase2_1,Phase2_2 ...
Put in all PRIMO files include the tmp-file you will split.

To begin , save all done Phase2 TEST [1..22] in a "master"-file.

Example: a second core will also calculate Phase 2.
- Copy the tmp-file,like the TMP-file with TEST [1..228] to \Phase2_2
- Kill the "-" of each Type=-? [1..4] for TEST [1] to TEST[100], set pe=2

- start PRIMO, Primo did start Phase 2 at TEST 101
- When you calculate TEST 230 , 231,... then kill the "-" FOR TEST 1 to TEST 229 , set pe=2 and compare the S$ of TEST 229 old file with the new tmp-file. Is it equal , so okay . Is not, so was on TEST 229 a backtrack and look then TEST 228, 227 and so on.
