Quoting Joe Landman <joe.land...@gmail.com>:
What does numastat report? /tmp is a ramdisk or tmpfs? Are the
nodes/cpus otherwise idle? What does lscpu on a good/bad node report?
/tmp is tmpfs. The node is completely idle. lscpu is identical for the
slow and normal ones as shown below. The numastat output is shown
after that.
