I was curious if anyone can provide BeOS precombiled objects of the Woltman objects. I retrieved Win32/Linux ones from Woltman's original code but I fail to...

Hi there Louis ... The Linux ones should work just fine - they are in position-independent ELF object format, and I can link OpenPFGW with them using the...
Chris, Thanks for the prompt reply. I was hoping the ELF objects could be used but something told me it wouldn't be that simple. I'm excited to hear that it...

... One last thing, make sure mult.o is linked on a 32-byte boundary. You will get your best performance that way....
Things are finally returning back to normal on my end, so if the source is ready, I can compile a Linux binary. In the latest source in the files area, all of...

I know this is an old bug, and has "magically" gone away, but I believe that I have found out why it was occuring, and now can look for other possible problems...
... Did I miss something? I still cannot find a linux dev_build with a big modular sieve. Sorry to be greedy, but it's frustrating to have linux cycles to hand...
Sorry, I sent the email asking for the latest source from Jim, then completely forgot about it. Jim: Is the latest source ready for a linux compile, or...
... What is in the files area (and the latest build which is on my PC's) is not ready for a Linux build at all. The configure scripts need editing (new files...
I should have said (I always forget the good news) that Greg's old linux build is A1OK for me in all respects save the modular sieve limitation to 31 bits. I...
If that is the case, and if Greg still has a buildable environment of files which built that version, then he may simply be able to insert the current...
Tonight I'll pull the stable source code off the website (20020129) and try it. Wait...isn't it in the 20020311 DEV source on the website? I'll try to...
The > 31 bit mod factoring should be in either of those "stable" releases I believe. I think that Phil worked on this last year (November or December rings a...
Greg, You may want to look long and hard and make sure that the "Phil - **** " text is not being output. I think it was wrapped in #ifdef (DEBUG) .... #endif...
Jim, That code is enclosed in #if !defined (NDEBUG) ... #endif so it has to be explicitly disabled. You may want to consider using an #ifdef instead so we...
I have looked through the pfgw.txt and searched these forums , but i see no information on what happens when pfgw runs on a system with duel cpu's. Is it...
I should clarify my question more. Some of the other prime programs had command line switches to run different instances on different machines, and the...
I run it all the time on 2 CPU's. It works fine. Now that being said, we could squeeze just a little more (1 - 2% more) from one of the running instances if...
Regarding modular trial division, and taking on a normal... How does a (shallow) P-1 test sound? Sometimes it's not worth trial dividing really deeply, and a...

Hello, I am trying to use the libgmp-3.dll with the gmp.h included in the 20020421_FULL_SRC.zip source distribution. My goal is to write a simple GMP based...
Using GMP within VC as laid out in the PFGW project is not 100% straight forward, but it does work. 1. The GMP dll has been built without any import library....
Jim, I continue to recieve errors. I think it is since I do not know how to properly link the .a and .dll files. VS's docs are unclear to me. I get the same...
I use #pragma comment (lib, "libgmp.a") and the others, and then you have to have the .a files in the current directory, or have them in the path of the...
