How long will http://uwin.mine.nu/PRPNet/ be down? I have a new 24 core server I'd like to start hunting primes on. http://isup.me/uwin.mine.nu says its not just me. (:

4) Message boards : Problems and Help : prpclient kills itself, unable to determine why (Message 92852)
Posted 1177 days ago by Profile geeknikProject donor
So I'm running the prpclient and it runs fine up until it tries to work on a Wieferich work unit and then it kills itself as seen here. I'd love to know how to fix this. Considering it's running on a headless machine in the corner with nobody connected to it (and no keyboard), it is impossible that someone did a ^C on it. Thanks.

I just ran this on my Dell T3500 (quad core Xeon workstation) that has a ATI FirePro V4800 (FireGL) w/ 1GB RAM, and it seems to run fine. Makes the desktop a little laggy, but otherwise, no problem.

My team was #58, I was #209. Not bad. I think I had 10 cores, 18 threads going on SGS 24/7 for the challenge. =) Time to switch everything back to PRPNet.

Just wait. Someone will end up spending 45 hours on a work unit and find a monster prime. And I'm willing to bet it won't be me. ;)
