The Third Megabit Drive
 

We are starting the Third Megabit Drive.
The k's on this current drive, as of 30 May 2014, are at level n=1.4M therefore the goal of this drive is to take them up to 2M. Goal can be prior extended.

The k's of this drive are:

203, 205, 219, 227, 235, 257, 259

[B]Update (June 03, 2014):[/B] adding k=275 and k=295 to the drive from n=1680k. Range n=1400-1680k for both k added as "batch 2".

[B]Update (June 08, 2014):[/B] batch 2 completed.

[B]Update (July 09, 2014):[/B] The drive is completed to n=2M.

[B] Update (June 16, 2015):[/B] Reopening the drive from n=2M.

Please help yourself and happy hunting! :smile:

Hi Carlos

Thanks for starting the drive. I'm busy right now but will join the drive soon.
Happy hunting! :smile:

Taking 1400-1404.

Edit: Fast machines can test a candidate at n=1.4M in 500 seconds or less. Come on guys!

Sorry for not splitting the input files into chunks but I don't know how to do it automatically. Also as the numbers are very fast to process, on latest Intel processors they can take less than 500 secs, I don't know what is the optimal chunk size for now for this drive, if 2k or 4k or 6k, for a period of 7-10 days of crunching as usual done on the other drives.

Carlos

Taking 1404 to 1408

About automatically splitting the files
 

I may be able to help you out by automatically splitting the files if you want. Do you need them in splits of 1000 or 2000?

I splitted the 1.4-2M input file into 2k blocks (see attachment). Each block contains about 400 test candidates.

The attached ZIP file also contains a file called "url_list.txt" indicating the FFT lengths and percentages (for non-AVX machines). This file is only relevant for Kosmaj when uploading the files to his server...

[I]Edit:[/I] Attachment removed. Please use the file in the top post of this thread...

Taking 1408-1412.

Taking 1412-1418.

Taking 1418-1430.

Hmm... going though them faster than expected, 2k done. Taking 1430-1450. (separate reservation if possible please)

Yep, they run fast. My first reservation is 60 % complete and I think from now on until we reach next FFT jump I will start reserving a 10k block per core.

Carlos

I'm running it at 2600 sec a candidate with 4 cores, my fast computer is working on the 8th drive. I'll have my range done in the next 6 days or so.

Taking 1450-1600.

[QUOTE=Batalov;374843]Taking 1430-1600.[/QUOTE]

kracker reserved from 1430-1450.

Ok, then.

Now you know that it is a full-time job to be a "manager" (or a "make-surerer", take your pick) of a drive. Please be fast and update the reservation post fast so that the users are not confused. You have been in the shoes of a user for too long. Now, learn to be an effective manager. ;-)

[QUOTE=Batalov;374845]Ok, then[/QUOTE]

Now you just need to update first post.
kracker reservation was in the middle of a conversation and therefore probably unnoticeable.

It is not my fault...I am a simple cruncher not moderator.

Talk about being confused.

Why do you start a drive that you have no intention of managing, then?

[QUOTE=Batalov;374847]Talk about being confused.

As many started here by others. Kosmaj gave me permission to start it. Also the current three moderators can handle the work although I think it misses one from side of America's (north and south of America). One is in the UK, other in Japan and the last one in Germany.

1450-1600 is done.
Carrying on to 1600-1680.
Results will be in one file.

Thank you Batalov for the push.
Meanwhile here are the Nash Weight of the k's:

k=203 - NW=1687
k=205 - NW=1351
k=219 - NW=1069
k=227 - NW=2550
k=235 - NW=1241
k=257 - NW=1867
k=259 - NW=1561

Carlos

EDIT: Damn, I didn't see the k=275 still in n=1.4M. It should be on this drive too.

I can run 275 from 1.4M to 1.6M then we can enter it into the drive past there.

[QUOTE=Trilo;374936]I can run 275 from 1.4M to 1.6M then we can enter it into the drive past there.[/QUOTE]

The files slitted in 2k blocks were already prepared so I think it is better to run it alone until 2M. How many cores do you have? Do you have the file?

I will have 4 cores available once my reservation on 1404-1408 is finished. I can get the files from primegrid's sieving files.

If you are not going to add it to the drive then I won't test it, but if you want to add it to the drive then I will test it.

Let's wait for Kosmaj or Thomas reply.

[QUOTE=pinhodecarlos;374941]Let's wait for Kosmaj or Thomas reply.[/QUOTE]

That's fine. 275 has a weight of 1581 so it won't take too long to test.

[QUOTE=pinhodecarlos;374941]Let's wait for Kosmaj or Thomas reply.[/QUOTE]

I've added k=275 to the input files starting from n=1680k.

The ZIP file in the first post of this thread has been replaced and now contains the whole file (rps_M3.txt, n=1680-2000k) as well as the split files (2k blocks).
There is also the file for k=275 included (t17_b2_k275.npg, n=1000-2000k) for individual testing the n=1400-1680k range.

Thomas, k=295 is also stopped at 1.4M. Let's add this one too?

[QUOTE=pinhodecarlos;374951]Thomas, k=295 is also stopped at 1.4M. Let's add this one too?[/QUOTE]

Okay, it's been added too.
The ranges n=1400-1680k for both k (275 and 295) are open for individual testing. Please post your reservations and results to this thread.

1450-1680 is done, 3 primes.

1402-1404 complete, no primes. (7 k's)

Taking 275 and 295 from 1400 to 1420.

1400-1402 complete, no primes. (7' k's)

Ok, I'll catch up the batch 2 from 1.42 to 1.68.

...and taking 1.68-1.72 (all k)

1418-1430 no primes.

[QUOTE=Batalov;374995]Ok, I'll catch up the batch 2 from 1.42 to 1.68.

...and taking 1.68-1.72 (all k)[/QUOTE]
Both done and attached. 2 primes.

Now that the 2 extra k's have been all caught up, I think we should remove the "batch 2" part of the reservations to avoid confusion when Carlos is done with his range.

[QUOTE=Trilo;375073]Now that the 2 extra k's have been all caught up, I think we should remove the "batch 2" part of the reservations to avoid confusion.[/QUOTE]

Not yet, I am still doing a little part. More 4 days.

[QUOTE=pinhodecarlos;375074]Not yet, I am still doing a little part. More 4 days.[/QUOTE]

Yeah just realized you were not done with your reservation and edited my post right as you said this :max:

My reservation is 25 % complete. The server has 6 cores available that I could use but I don't know if I should. There's no queue work system, work is inserted manually.

1412-1414 complete, no primes. (7' k's)

Taking 1720-1728. (9 k's)

1430 to 1450, no primes.

1400-1420 complete, no primes. (2 k's - batch 2)
Maybe clean on first post in order?!

I was wondering if it isn't better to switch the order of the status progress by putting the batch 2 information in first. Thoughts please?

taking 1728 to 1740

1414-1416 complete, no primes. (7 k's)

1404-1408 complete, no primes

[QUOTE=pinhodecarlos;375348]I was wondering if it isn't better to switch the order of the status progress by putting the batch 2 information in first. Thoughts please?[/QUOTE]

Now that batch 2 is complete, I say we remove it from the list entirely.

[QUOTE=Trilo;375421]1404-1408 complete, no primes[/QUOTE]

Please attach the results.

Taking 1740-1750.

Batalov,

My range 1818-1854 is in progress like this:

1818-1820 in progress
1820-1834 in queue
1834-1838 complete
1838-1854 in queue.
1862-1866 almost complete.

Do you want to crunch the ranges in queue? If so please let me know so I can add work from Second Megabit Drive, where I want to concentrate from now on my efforts.

Carlos

No, let's keep it simple, as is.

[QUOTE=Batalov;377412]No, let's keep it simple, as is.[/QUOTE]

Thank you and happy crunching!

My ranges below 1854 will take at least one month, I am now down to 2 cores at home and so far 10 at work. 1862-1866 will be done within max 2 days, so of the 10 cores more 4 will be down soon, leaving 6 to finish my current SMD reservations. By Monday all 10 cores will complete their jobs.

Hi Carlsos,

Please consider releasing your second queue (1838-1854), thus speeding up the processing of the first one and giving a chance to others to complete the range of the second queue and the whole Drive to 2M faster.

Thanks.

[/code]I need an answer, almost midnight here, I want to sleep but before I go I need to reserve a SMD range to one of the cores.

Releasing the ranges in bold from previous post. I think it will be quicker if done by others rather by only two of my laptop cores. Tomorrow I will publish 1834-1838 results.

Going now to bed. Bye.

Carlos

Thanks!

I just uploaded remaining test files to my server, and added links to them in the first post of the thread.

1834-1838 complete, no primes.

1862-1864 complete, no primes.

I am going to dedicate one core here one core on SMD.
I ask for some help to help to clean the drive up to 2M. On my laptop each candidate is tested in less than 1200 secs so I suppose with processors with AVX 2.0 it will crunch in less than 900 secs.
Within 2 days I will reserve another 2k chunk.
Meanwhile 1864-1865 is complete, waiting for 1865-1866 (5 candidates left), and another core down for me.

Carlos

1864-1866 complete, no primes.
