Hi!
I am a new Maui users and I have observed some "strange" behavior that
currently doesn't make any sense to me: I have a small cluster and it
can happen quite often that jobs are submitted, which require all
cluster nodes. Even when no other jobs are in the queue and both Maui
and TORQUE report that all nodes are available, jobs that request all
cluster nodes remain queued for an unpredictable amount of time
(sometimes minutes, sometimes hours). When I try to force Maui to
execute the job immediately it reports that the nodes cannot be
allocated. When queuing jobs that request fewer nodes they get executed
right away. Is there any reasonable explanation for this behavior? (I am
using the latest releases of both TORQUE and Maui and the only major
change I have made to the default configuration of Maui is that I have
changed the node allocation policy to CPULOAD.)
Thanks,
Jochen.
