Jim, I've been trying to contact you via e-mail, but it appears that you are not getting e-mails from me. Simply put, I know that you have been PRP testing...
How does pfgw evaluates phi(x,y)? I found this number to be a PrP, but can't write it in a more palatable way: Primality testing phi(30,2^4200+13) [N-1/N+1,...
... By multiplication and division of Phi(d,y) terms for d|x. ... There is no more palatable way. It's both succinct and clear, and you can't ask for more than...
A beautifull day, Is there a date for the next release of openpfgw 1.3 . It would be nice, if someone knows it. Best regards from the primes Bernhard...
I believe there is a problem with writing exceptionally long pfgw.log files. I am using the command line pfgw -b107 xxx.inp with an input file coming from...
OpenPFGW (win32) uses FILE structures, which under VC (and MinGW), uses a 32 bit max sized file. I would assume that 70m values in the pfgw.log file pushed...
Thanks Jim. I understand that there are several ways round this. However... This problem came upon me unawares, and could do the same to anyone at any time. A...
hello, I have been following this thread about the log file of pfgw being too large. I use cygwin to run pfgw and I can manipulate files that are larger than...
Hello Mike, ... What do you mean by "quarantineing" the files? What kind of filesystem do you use on your disk, by the way (FAT32? NTFS?) ? Have you tried to...
... I agree with the conclusion (and of course, move each pfgw.log aside before ... Each pfgw.log line will be 4 characters longer than the above. "a b" ->...
... PFGW doesn't write any files. It asks the OS to write data to the filesystem. That's what OSes are for. ... This OS bug. ... Same company - same mindset. ...
... The HD file system is NTFS. After a reboot, you can /rename/ the file pfgw.log, but any attempt to delete it causes the command prompt to go to 99% cpu...
... You assume I am presuming. I'm not. I _know_ what an OS's job is, I don't have to make guesses. ... 1 fopen, many fprintfs/fputss, 1 fclose or many {...
This "bug" is most likely compounded due to the fseek in PFGW. However, step back for a second. First off, why are you using PFGW to PRP test a*71#+1 ?? PFGW...
... It's done in a very simple manner (don't have the actual sources by hand; checking somewhat older version but I really doubt it has changed much since...
... That looks like 2^30 bytes minus just under 1 MB of unflushed cached writes. ... This sounds like a case for backing up your data - writable DVDs, CDRs, ...
No-one seems to have pinpointed code which could explain where misbehaviour at c. 1 Gb o/p file size is coming from. [BTW NewPGen, which Paul J tells me also...
... Paul found it - it's either or both of the "t" in the fopen mode, and/or the unnecessary fseek. As DOS users like their carriage returns, I think even ANSI...
... Mike - you are backed up, I hope? Keep the fseeks out, and turn "at" into "a", and append a carriage return explicitly? Only "t" would explain non-Theta(1)...
Hello Which checksum is better for archive? pfgw 99*2^100006+1 is composite: [22E3D742CD3DC966] 99*2^100031+1 is composite: [27BFE3AFADCFC9A7] 99*2^100053+1 is...
PFGW and prp are the same (as long as pfgw is doing a Fermat-3 check). LLR is a totally different exponentation, and can not be used (AFAIK) to compare...
