Hi all, I am using lm-sensor on a dual-quad-core system with two Xeon 5460. I am running a periodic workload on one of the cores: 400ms computation and 600ms idle. >From the thermal side, the temp reading is shown in the figure attached. Notice that there is a very obvious oscillation in the temperature reading on that core. The oscillating period is around 20-30 seconds, which is definitely not sub-second. I've no idea what's going on here. Can anyone share some thoughts? Thanks a lot! -Simon -------------- next part -------------- A non-text attachment was scrubbed...
