dswanson,
No posting on this forum is not sufficient. Also, one of the numbers in that range is still out for a first time test. You should probably email George to sort this out and/or look at HRF3.TXT from his status page to see which numbers you want to test.

dswanson · 2003-03-01, 06:05

Garo,

I've already pulled hrf3.txt and removed the one first-time test remaining in this range. I also pulled pminus1.txt and determined which ones still need P-1. I'll be doing that as well for the 61% of this range that hasn't yet been done.

I'll email George directly to officially reserve this range.

Dan

completely new topic - prolly a dumb question even

there's no way we can submit lmh results to get primenet credit, right?

also, is there a way to view our "gimps" credit as per what is read on the manual submission pages?

idk - it just seems kinda depressing at times to have that primenet number of p90 years stay at a total of about 22...

Every kind of help is welcome. So are your questions.

In short form: We do uncredited pre-factoring work for GIMPS. Some of us do it just for fun, some do it for the purpose of maximizing GIMPS throughput by putting machines (even old ones, like PII 200 etc.) to the kind of work they can do best.
But read the other sticky threads in this forum first...

i can't understand what this meant

34.0-34.2M 62 63 or 64 bit (next in Primenet)

34.0-34.2M : a range of exponents, ie. 34,000,000 to 34,200,000

62 : factoring status of these exponents according the last nofactor.zip file, ie. most of the exponents are pre-factored to 62 bits

63 or 64 : wanted bits level for factoring (bold = a most wanted range)

next in Primenet : will be released to Primenet soon, ie. not much time left for factoring, frequent submitting of the results recommended

Does this quote still strictly apply? With the recent optimizations related to the AMD 64, would an AMD 64 work as well as a P4 or is it still advantageous to do this work on a P4? Thank you.

I would say that with new optimizations etc. the Pentium-M and Athlon-64 are best for factoring.

hbock · 2005-07-13, 23:10

I would say, it depends. (exception : AMD64 in 64 bit mode !)
I've collected some own data as well as data obtained with the AMD64 (look this thread , obtained with version 24.11)
Please note that these are not the fastests version nowadays, you can get easily 10-20% (or even more) performance but the ranking will remain the same.
