Hello, The following routine is the fastest mult64x64 on my PC so far. void mult64x64(u64 *c, u64 *a, u64 *b) { multnx64(c, a, b, 64); } When I improved multT,...
Hello Everyone ... Well. Ok. Let's do final comparison of mult64x64 routine speed on different CPUs. So, I'm asking everyone to submit results obtained from...
... It looks as if mult64x64_k5h is the best in my environments: 1.8GHz P4 (MSVC v8): Routine mult64x64_k5 takes 27 seconds. Routine mult64x64_k5h takes...

Hello, Results of test1.c, including mult64x64_k6 which uses SSE2, on Pentium 4 3.06GHz, Windows XP, Cygwin and gcc-3.4.4: #define ITERATOR 0x100000*32 #define...
Hello KAMADA Makoto! test1.c updated. Please see my small bugfixes, if I not right, please correct me. Added ALIGN to 16 to all memory blocks, becouse SSE2...
... <http://www.hoegge.dk/mersenne/ggnfs.log.txt> How long did this factorization take? It looks like you used factorbases of 5M, which is rather large for a ...
... given ... Well, all in all it took a long time cause it is my first nfs factorization, so I had to figure out the program first. I sieved several times in...
Over the last month I've only seen it happen 3 times. The sieving will be going along very nicely at a fast clip and then something slips its gears. It'll...
I've been using factLat.pl to do multi-client sieving. It took me a few days to figure out all of the "gotta do" issues, but now it seems to be working great....
Due to the recent posting I did on factLat for multi-client, I've had more than a few people ask me how to do "it" (multi-client support). I've done a couple...
... It is very well doable from Win32. I've quite a few cpu's available on which i can't install cygwin. I haven't read your steps in detail, but i think it...

... I've been hoping someone would take the time to do just that for quite a while now. Something simple like the ECC challenge clients to distribute the...
Dear GGNFS users, I've had a great deal of success making use of the perl script and even running the programs independently to factor a fair number of ...
Is there any way to decrease memory usage in matbuild, I'm following using params: 1) C168 type: gnfs rlim/alim: 21m/20m lpbr/lpba: 30/30 Memory allocation...

Hello sashamkrt ... I hope so, in fact we depends heavily on the "quality" of the system memory management facility. The only solution, which can be useful - ...
... Have you tried reducing the -maxrelsinff parameter to matbuild? This should reduce the matbuild memory use, at the cost of increased matrix size in...
... Do you want to know how the GNFS *algorithm* works, or how the GGNFS *program* works? Others can comment on the latter; for the former, google Per Leslie...

hello actually i want to understand GNFS in some simple manner the way it is presented in the Papers makes it too hard to understand for me. can you tell me...
Sorry, but there is no simple way to desribe NFS. It is the most complicated factoring method today and is more than 2 orders of magnitude more complex than...
... Indeed. If you understand how the quadratic sieve works, and can learn enough to know what a number field is, you're most of the way to understanding how...
