1.  MAUI wrappers



1.1  showbfq


"showbfq" shows the per-queue node availability (instead of the total as provided by showbf)

$ showbfq
blade:              no procs available
myri:               no procs available
smp:                  4 procs available with no timelimit
up:                 no procs available
zebra:               48 procs available with no timelimit


1.2  showload


"showload" shows the load status of the nodes. As command line argument it accepts a regular expression matching the host name(s).

$ showload p
p001     Busy  2.00 ====================
p002     Idle  0.00 
p003  Running  2.00 ====================
p004     Busy  8.07 ================================================================================

p021     Busy  8.05 ================================================================================
p022  Running  2.00 ====================


1.3  nodeavail


"nodeavail" shows the estimated time availablity for reserved nodes (or a specific node or group of nodes) based on reservation timelines. Since it's based on "showres" output, nodes already available (currently free/unused) won't be shown. As command line argument it accepts a regular expression matching the host name(s).

$ nodeavail p
p012 available in 2h 1m 4s, waiting for job 71481  @7264
p014 available in 2h 1m 4s, waiting for job 71481  @7264
p015 available in 2h 1m 4s, waiting for job 71481  @7264
p016 available in 2h 1m 4s, waiting for job 71481  @7264
p004 available in 2h 1m 28s, waiting for job 71606  @7288
p010 available in 2h 1m 28s, waiting for job 71606  @7288
p013 available in 2h 1m 28s, waiting for job 71606  @7288
p021 available in 2h 1m 28s, waiting for job 71606  @7288
p003 available in 4h 21m 5s, waiting for job 71169  @15665
