1) Message boards : AP26 - AP27 Search : New feature with latest AP27 gpu application (Message 126514)
Posted 130 days ago by Profile roadrunner_gsProject donor
Hello
The APP27-version 2.03 is not compatible with Red Hat Enterprise Linux 6 any more.
My rig http://www.primegrid.com/results.php?hostid=222147&offset=0&show_names=0&state=7&appid=11 is failing with
../../projects/www.primegrid.com/primegrid_ap27_2.03_x86_64-pc-linux-gnu__OCL_cuda_AP27: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by ../../projects/www.primegrid.com/primegrid_ap27_2.03_x86_64-pc-linux-gnu__OCL_cuda_AP27) ../../projects/www.primegrid.com/primegrid_ap27_2.03_x86_64-pc-linux-gnu__OCL_cuda_AP27: /lib64/libc.so.6: version `GLIBC_2.17' not found (required by ../../projects/www.primegrid.com/primegrid_ap27_2.03_x86_64-pc-linux-gnu__OCL_cuda_AP27)


Only found out now.

Since Red Hat Enterprise Linux 6 (or Centos/Scientific Linux) is still in the wild and supported until July 2024, would it be possible to get this running with glibc_2.12?

Hm, even in standalone-mode via the console i do need 1.5 GB of RAM and the app checks for it?
I know i started the old app on a Nvidia Quadro FX 580 with only 512 MB RAM way back in late 2009.
Anyways i got no spare card that satisfies the RAM-requirements, that is sad.

"Use GPU when computer is in use" is enabled.
This is a Scientific Linux 7.2 with kmod-nvida installed.

What have i missed?

(old app is working on the command line, though, gives me the AP25 for 366384 366384 0 in 39 seconds )

So this is still the same app as for the AP26 search, CPU and GPU-wise?

Server load seems a bit high, site is not too responsive but i get work every now and then plus i am able to report. WUs waiting for validation is climbing up, but that's what was to be expected.
Any idea when the individual stats are pouring in?

I think Intel should release Knights Corner for the end-user. ;)

I do think i had 3 primes in february, 2 more in march if i remember correctly - still waiting on those to appear in the primes-list. Alas one was reported to the primes-page two days ago, i do think the doublechecker was late on that one.

Last time i looked into ATI it sucked, the approach of Nvidia to develop apps is way better.
And only AMD 79xx seem to have superior DP-power, a AMD 7770 has 80 GFLOPS DP, a Nvidia 560 has around 90 GFLOPS DP. (1/12th of 1089 GFLOPS SP).

I don't know, i am only at 69.x % by now, need two more days i do think.


82.16 % by now, flaged as "time exceeded"...
