The probable primes - Page 20

Thanks Norman, I wasted 10 days going back and forth on the first 8 test. Got tired of it and re initialized the same test. I am now on test 8 after only 1 day and have not backtracked yet. I guess the first initialization was corrupted or bad. I should have dumped the first one sooner but I did not.

Well having Phenom x4 965 is way better than a Q6600. With a small oc it did 10^700+7 in 2min 20s.

2^31544+19081 is 9496 digits only. I am using Primo3.0.9, is it different than 3.0.7?

From the changelog:

Quote:

v3.0.9
The [Comments] sections of input files are reported in the [Comments] sections of output files.
v3.0.8
Added a Double file management option. It might be useful when dealing with very big numbers.

Thanks Ben, I've read that too. If I am not mistaken the double file management option came about after I and either Gary or Luigi had a corrupted *.tmp. I had to restart my test after almost halfway done, now I hope this will prevent this from happening.

I was asking Norman more as far as how we save certain files on the process he developed.

8 TEST only one day is very good ! 2-3 is normal. V 3.0.9 is the same like 3.0.7. No speed ups.

OC's make no sence, because the temperature is ever critical (>60°)...
and we have winter ! In summer , my roomtemperature is 30° or more

The black edition works stabil with Vcore=1,265 V ( default=1,4V ) so the temp go down from 60° to 50°. Every core works with 100%.

BTW , the Phenom 965 with MSC=20 can TEST 10^700+7 in 2min 00s

Norman

Yea it is good that most except for one test was run 1 and the early part of run 1 at that, meaning the index are at least less than 25,000.

I thought that since it is a bigger prime, the slowness of the first test was normal. But when I backtracked twice on the same 4 test, looking like it was going in a loop, I stopped the test and started again. It was early enough for a restart.

Thanks for the info.

That is typical for PRIMO. When you found another TEST n [ Example 10 with 31089 bits and later 10 with 31095 bits ] then you have to do delete the old *.s10 file. I had have also this problem. Normally PRIMO delete *.s file automatic and then PRIMO make a backtrack....found another TEST n and create a new *.sxxx -file.

Do you remember ?

Do you know how many test is on 2^26827+77783. Thanks."

I said :"Between 1065-1075. "

Really exact 1076 TEST, 1076:Type=0

That just about the limit !!!

engracio · 2010-02-05, 01:05

Technically the prime consisted a total of 1075 test, test 1076 is like the end of file. So yes Norman, you hit on the head.
