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... Luigi

MM36 behind schedule
Hi all,
As you all know, I am trying to test k's of big double Mersennes starting from MM34. 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*(2^29762211)+1 // $a is the k to be tested k k k k Luigi Last fiddled with by ET_ on 20140326 at 16:04

With pfgw you can do about 6 candidates per day per core on a i5750.
The range 30,00040,000 has 187 candidates. How many k do you want? 6, 18, 36, 72, 90 or 187? Handtaylored just for you... Luigi Last fiddled with by ET_ on 20140326 at 16:44

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. Last fiddled with by pinhodecarlos on 20140326 at 17:16

Luigi, Batalov helped me with the input files so you can reserve the range 30,00040,000 for me.
