Hello.

I have installed BOINC on a computer (Athlon 64 6400+) and wanted to run a benchmark (to find the best client). The benchmark is from this post.

With Kubuntu 8.10 (2.6.27-7.generic), it looks normal:

grubix@ubuntu:~/enigma_benchmark$ ./start
2010-10-11 19:27:48 enigma: working on range ...
2010-10-11 19:33:21 enigma: finished range

real 5m31.772s
user 5m31.753s
sys 0m0.040s


Now I have installed Kubuntu 10.4 (2.6.32-25.generic) and I am a little confused:

grubix@ubuntu:~/enigma_benchmark$ ./start
2010-10-11 19:50:32 enigma: working on range ...
2010-10-11 19:56:07 enigma: finished range

real 5m30.806s
user 2m2.448s
sys 3m28.273s

The total running time is the same, but now the most time consuming allegedly by the system. Why?

Little later I used a optimized client (from buninek). Again under Kubuntu 10.4:

grubix@ubuntu:~/enigma_benchmark$ ./start
2010-10-11 20:52:29 enigma: working on range ...
2010-10-11 20:56:09 enigma: finished range.
Best score: 1760525

real 3m39.766
user 3m39.702s
sys 0m0.028s


It looks normal again, but now am even more confused. What's up with the systemload for the default client under Kubuntu 10.4?

Thanks for the help, Grubix.

I have no idea what's wrong. The default app has no optimizations but it should run fine, without any surprises like that.
The best solution is building your own app, directly on the target system. It should have the maximum compatibility and speed.

OK, thanks for the reply.

I think it's because I do not get turned off the powersave management at Kubuntu 10.4. With Kubuntu 8.10 it was no problem with "powernowd".

Bye, Grubix.
