Load-Testing HPC Linux Clusters with “stress”
on April 28, 2011 – 8:43 pm 5 Comments
The “stress” is a simple-to-use load generator for POSIX systems that I found very useful for stress-testing HPC clusters. The current version of the application is 1.0.4 and it was easy to compile and install. Stress can create configurable system load for CPU, memory, I/O, and disks. In the example below we ran “stress” on a SLES 11 HPC cluster with HP CMU 4.2 installed. The stress test was initiated from the cluster head node on compute nodes 17-32. The pdsh parallel distributed shell was used, which is a part of the CMU package.
pdsh -w node[17-32] "stress --cpu 10 --io 1 --vm 1 --vm-bytes 128M --timeout 30 --verbose &"

I take 240mg of verapilmil to control pvcs. My stress test showed “non-diagnostic” st depression for heart disease. I can’t see the cardiologist for another 3 or 4 weeks. Should I be worried? I am healthy and have never had chest pain, shortness of breath, etc. I am waiting for echo results and holter results. Can someone help me relax about this? Thank you.
Hello I just had a stress test 2 days ago and they injected some nuclear tracer dye. I am wondering if it is safe to have sex after 2 days?
I have looked and have a good idea of who most of the banks are under the stress test, but does anyone absolutely know numbers one through 19? Please list them if you know.
Thank you in advance.
I had a stress test done to me last Monday and I got tired.is that normal?
About 1 month ago I went for a stress test at a Specialist Centre. The doctor after examining the result of the stress test done, told me that the result is not good . He suggested that I go for an angiogram.
