OFFICIAL "SERVER PROBLEMS" THREAD

[ewmayer]

Please post any information about problems you're having with the PrimeNet server here.

Note to the Moderators: Please clear posts out of this thread as the relevant issues are resolved, or the problems simply go away due to server reboot and such. Posts that prove to address specific problems that are not merely due to transient glitches or server-is-down-ness and where a server-side fix is needed should be moved into separate threads. Thanks.

With the implementation of PrimeNet v6, perhaps it might also be a good time to re-benchmark the GHz-day unit to a more modern CPU architecture.

Also, I would assume this probably will spell the end of the v4_computers, if indeed any are still contributing on a regular basis.

I'm 99% there. Thanks, James. The only remaining issue is generating a unique filename for YAFU to write to instead of the fixed siqs.dat.

People fought replacing P95-years for a long, long time. I suspect they'd fight changing GHZ-days too.

I'm still getting several DCs a day from v4 computers. It turns out people are still downloading v24 prime95. Apparently, one can still create new v4 user IDs, get work, and report results. There is a PHP script that turns v4 requests into v5 requests, so there is no reason not to continue supporting v4 computers.

Apparently there are still V4 results coming in on a daily basis... go figure. There's a PHP script that takes those old incoming calls and converts them or whatever to the correct V5 looking stuff.

That's actually one of the things we need to test out and make sure I set it up correctly.

I wouldn't call this upgrade V6, it's more like V5.5. The client/server communications are unchanged after all.

I don't know how PHP does it, but a call to the system's GUID generator should ensure uniqueness. I'm just assuming PHP has something like that, otherwise a randomly generated one is probably just as good.

I have PARI/GP working very nicely on both Windows and *nix. I can't say the same for either yafu or msieve (not saying it can't be done, I just haven't managed it).

My preference is for PARI/GP, it works well for me.

Oh, keep the GHz-day as a unit, but just recalibrate it to say, a Haswell instead of a Core 2 Duo.

Wow, never would have thunk it. We probably should get any mirror sites to update their outdated Prime95 links as we catch them.

Md5 hash of the input number should be good enough.

I just got a CGI timeout on a batch of mfaktc results which included two factors. 0300 UTC, 8/10/2014.
