RPS with Prime95
I need some guidance.
I got the indication that to run a PRP on Prime95 with numbers of the form "k*2^n1" I should add the following line at the worktodo.txt file: "PRP=k,2,n,1" Now a few questions. Imagine I have a cluster so how do I add work? Do I need to create a separate [Worker thread #n] lines where "n" is up to the number of cores available? Or Prime95 detects all cores and I simple need to add the work after the line "PRP=k,2,n,1"? Other question is how to put the LLR input file into worktodo.txt of Prime95. 1) Is it "PRP=k,2,n,1" 5,2,3900000,1 or 2) "PRP=5,2,n,1" 3646020 3646040 etc. I need some help. I've been testing but I can' find the right way to run PRP with Prime95 on numbers of the form "k*2^n1". Thank you in advance, Carlos

WorkerThreads=4 (change 4 to how many physical cores you have, do not count hyperthreaded cores) ThreadsPerTest=1 In worktodo.txt you need to do: [Worker #1] PRP=100,2,216091,1 [Worker #2] PRP=101,2,216091,1 and so on. Quote:
[Worker #1] PRP=101,2,216091,1 PRP=102,2,216091,1 PRP=103,2,216091,1 PRP=104,2,216091,1 [Worker #2] PRP=105,2,216091,1 PRP=106,2,216091,1 PRP=107,2,216091,1 PRP=108,2,216091,1 Last fiddled with by ATH on 20130912 at 11:54

Prepare NPG file for Prime95
In excel table copy NPG contents ( row A) ( example) 2211 123456 (means >) 2211*2^1234561 Replace 2211( and one blank space)  very important with PRP=2211,2, Result will be PRP=2211,2,123456 Then in row B add formula =A1&",1" ( or change +1) if you need for proth then pull cursor down, and result will be PRP=2211,2,123456,1 ( then copy to worktodo.txt) Last fiddled with by pepi37 on 20130912 at 12:03

Thank you both. How many workers can Prime95 detect?

Is the speed of Prime95 and cLLR 64 bit the same or is LLR better?

I just love Prime95 for two reason 1. it has nice GUI, and it removes candidate when finish it 2. it can be used for very fast PRP checking of one candidate :)

Prime95 doing PRP is new information for me. I also like Prime95 since it can run multiple threads at once and can also do ECM and P1 work which is very useful for low weight k's. No more creating 8 folders etc...

P95 was doing PRP for ages. I've used to for near/quazirepunits for over half a decade.
The only thing to remember that you still have to prove the prime, while with LLR your done at arrival.

You should bear in mind that some projects won't like prp residues instead of llr. That is probably the case for NPLB.
It would be nice if the changes to the gui/interface/threading were merged into llr. Since the llr gui is originally based on the prime95 gui I don't know how hard this would be.

There is 32 bit LLR gui, but there is no 64bit LLR gui. And since 64 bit LLR is faster then 32 LLR it is shame :( Also , when somebody will compile LLR with latest GWNUM Library? I got 32 and 64 bit for Linux LLR and 32 bit LLR for Windows with latest GWNUM, but not have 64 bit for Windows :( ( dont know how to compile)
