BTW, I had some issues with the scripting features of pfgw.

Trying to use GwPowMod and test divisibility of huge ks, I noticed that when k>1,000,000 the result is always 0, no matter what the exponent or the factor is.

Did you also notice such behavior? Maybe there iis a note in the readme that I skipped...

Unfortuntely, due to my lack of resources, MM36 is lying behind, so I'm looking for some volunteer that wants to help. Actually, MM36' k have been reserved up to k=30,000. Please note that each k of MM36 needs less than 4 hours to be PRPed, and in case it is found prime, you have a nice 900,000 digits prime to add to your collection. Is there anybody out there that wants to ? In case, I can provide my list of ks, presieved up to 2.5T. Luigi

I used pfgw, but I heard LLR can work equally well on it. It takes an abc file as input:

ABC 2*$a*(2^2976221-1)+1 //$a is the k to be tested
k

With pfgw you can do about 6 candidates per day per core on a i5-750.
The range 30,000-40,000 has 187 candidates.

How many k do you want? 6, 18, 36, 72, 90 or 187?
Hand-taylored just for you...

I want all because I want to dedicate two cores during one week to your effort but I want to use LLR instead of pfgw.

Edit: Please prepare me the LLR input file. If I get excited by this search I have more 6 cores I can spare to the search. Thank you in advance.
