Gonzalo E Correa commented on TRAFODION-2884:
---------------------------------------------
We should consider doing what you suggest. There is code in the monitor to use
the cores specified in the node section today, but by default, all cores are
used. It can be enabled by environment variable, SQ_USE_CPU_AFFINITY, which is
is off by default. So your suggestion makes sense. Perhaps a question to the
community in general would help to get some feedback on this. I can write up
the original intended use and what we would give up and see if there are any
unseen repercussion to making this change.
Good suggestion, by the way!
