73.5M-74.0M to 2^63
 

I would like to reserve this range.

I'm installing Ubuntu one one of my pcs (dual boot), so I'll see how mprime goes with this.

I should finish pre-factoring the range 1901M-1905M soon, then once I've emailed the results off the George, I'll put the other pc onto this range as well.

I've factored 40% of the range and sent the results off to george.

Mprime doesn't count the factors found automatically, but I counted around 73 factors found.

Is mprime the best factoring program for LMH under Linux?

For my windows box, I'm using prime95.

Best factoring program

I think so. At least for two reasons: (i) specialized for divisors of M(p) in a form 2kp+1 and equal to +/-1 mod 8; (ii) many parts written with machine language (x86-style processors!). Some known programs (follow links at [URL="http://mersenne.org/freeware.htm"]GIMPS[/URL]) use different large_integer libraries but only few of them use machine code.

Thanks.

I've completed the range 73.7M-73.8M and sent the results to George.

I've attached the results file below.

I've completed the range 73.8M-73.9M to 63 Bits and send the results to George.

I've completed the range 73.9M-74.0M and sent the results to George.

I Have now completed the range 73.5M-74.0M

Below is the results file for 73.9-74.0M
