Hi.
We have a cluster where all nodes have Gbit and some of the nodes have SCI
interconnect. I'm trying to figure out how to let users specify what network
they need for their jobs, after some digging in the docs I found that this
cfg lines should be appropriate:
#
NODESETPOLICY ONEOF
NODESETATTRIBUTE NETWORK
NODESETDELAY 1
NODESETLIST gige sci
#Only Gbit:
NODECFG[compute-3-0] PARTITION=Itanium2 FEATURES=Itanium2 NETWORK=gige
#Both types
NODECFG[compute-4-0] PARTITION=Itanium2 FEATURES=Itanium2 NETWORK=gige,sci
checknode reveals that maui has picked up these configs:
checking node compute-4-0.local

Reservations:
User 'itanium.0.0'(x1) 00:00:00 -> INFINITY ( INFINITY)
Blocked Resources at 00:00:00 Procs: 4/4 (100.00%)
But how do I specify that a job needs nodes with the SCI interconnect???
In my job script I put the line
#PBS -Wx=NODESET:ONEOF:NETWORK:sci
but maui disregards any network specification and starts the job on whatever
node is available:
checking job 495

This is for torque-1.2.0p0 and maui 3.2.6p9.
Any hints is greatly appreciated,
