PRPNet 5.4.3 Released - Page 13

rogue · 2016-12-20, 01:16

I did a quick test on the double-check logic. It looks good so I've committed the code changes. If you need a build, please let me know. BTW, this is now version 5.4.3.

What is the format of the file output from the sieving program?

lalera · 2017-01-19, 18:08

hi,
the (configurable) output format is from mfaktc v 0.21
http://www.mersenneforum.org/mfaktc
i do edit the results-file with a table-calculator
an example:
-
ABC(2^$a+1)/3
1500019
1500071
1500127
1500133
1500139
1500143
1500181
-
this is the input-file-format for llr

I've made code changes for the Wagstaff form and committed them, but have not tested. I don't know when I'll have time to do that. If you would like to do some testing, I can get you started.

hi,
thank you for making the code changes to support wagstaff numbers !
i like to do some testing
i need the executables

I won't post them here, but you can send me an e-mail or your e-mail in a PM.

LLR now has multithread support. Is there an existing way to pass command line arguments to LLR with PRPNet?
If not, can support for multithreaded LLR in PRPNet be implemented some how in the future? Maybe a parameter in prpclient.ini

It is not supported now, but it could be done.

I got LLR multithreading working on PRPNet.
Assuming you want to use 2 threads, first create a cllr64.bat:

Code:

@cllr64.exe -t2 %*

Then in prpclient.ini use the line:

Code:

llrexe=cllr64.bat

Where cllr64.exe is the llr 3.8.20 version copied into your prpclient directory.
This is for Windows, of course, but a similar shell file should be possible on Linux.
Depending on candidate FFT size and your CPU L3 cache you can get a good speedup, faster than running individually.

This is very helpful. Thanks!
