Hi All,
This isn't a problem with Ganglia, but I was hoping I might get a little advice on what I am seeing. I have a customer who is running ls-dyna applications, and he is noticing something odd. He is noticing his jobs being bogged down and not running at their full capacity. He looked at the Ganglia web interface and saw that "System CPU" was at 100%, while "User CPU" was at like 20%. What processes does the "System CPU" refer to? What tools can I use to track what might be pushing the "System CPU" to 100%? There are times when the "User CPU" goes up to 100%, which is what he wants, but then at times it spikes down to 20% ish and the "System CPU" stays up around 100%. Any advice is greatly appreciated. If you need me to send output, I certainly can. Just let me know what to run. Please let me know. Thanks. -- Kamran Khan PSSC Labs HPC Software / Technical Engineer
