Hi Andreas-san, Thank you for replying. I hope the problem will fix the next release. Best regards, Yoshiki Yamaguchi In Re: [suse-amd64] top command over 4GB. Andreas Jaeger <aj@suse.de> wrote:

Hello and guten Tag,
I have tested the HPL (High-Performance Linpack) benchmark on dual Opteron 240 with 8GB memory. SuSE 8.2 is very good because I could compile the benchmark and run it using memory over 3GB per process (x86's limitation). Then I noticed that the top command show false information when a process used memory over 4GB.

The xhpl process is using about 7GB memory. However, top command shows 2780m on VIRT and 2.7g on RES. So there is a turnup at 4GB. It is small problem since the process run well (performed 2.48GFLOPS).
I haven't noticed this before - we'll check it and will fix this for the next release.
Thanks for the report - and glad that it worked fine otherwise!
