[SCore-users] 128 limit on score 5.0.1

[Nick Birkett]

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 at snowdon sbin]# ./rpminit comp128 myrinet2kII
[root at snowdon sbin]# ./rpmtest comp128 myrinet2kII -dest 128 -ping
pmGetNodeList: No route to host(113)
[root at snowdon sbin]#


Regards,

Nick
