Subject: [slurm-dev] SLURM wakeup gets delayed.
Hello there!
We found that simple command such as 'srun hostname' executes at
random - from 1 second to tens. After a lot of research the cause of
that strange behavior was found - process of power save runs in own
thread and gets not always in sync with scheduler. Sure, if we had the
power management fully power off nodes that delay would be unnoticed
(and, probably it's why it was unnoticed before) but our power save
function just manipulate CPU frequency and such so delay 20 seconds looks
strange enough. As soon the cause was found the source is patched and
patch is in attachment.
Andriy.
