Just wondering if we have hit the 128 compute node limit on Score 5.0.1 ?
We plan to upgrade to 5.4 in the next 4 weeks.
We have 136 compute nodes configured with 2 Myrinet 2k fibre switches
128 hosts on a 128 port switch running batch
8 hosts on an 8 port switch running mult-user
There are 2 pm-myrinet.conf files pm-myrinet.conf (128 hosts) and
pm-myrinet2.conf (8 hosts), 2 myrinet groups MYRI and MYRI2 and
2 Myrinet networks - myrinet2k (128) and myrinet2kII (8 hosts) in
scorehosts.db.
(The opt/score/etc directory is attached as compressed tar).
Both systems work ok as long as there are no more than 4 compute
nodes (128,129,130,131) listed in scorehosts.db.
The compute nodes 132,133,134,135 are commented out in scorehosts.db.
Score multi-user is working fin on comp128-131 (4 hosts) on second switch.
However the mult-user system always fails the basic ping tests with
[root @ snowdon sbin]# ./rpminit comp128 myrinet2kII
[root @ snowdon sbin]# ./rpmtest comp128 myrinet2kII -dest 128 -ping
pmGetNodeList: No route to host(113)
[root @ snowdon sbin]#
Regards,
Nick
