Hi we would like to set up 2 SCore Myrinet clusters using a single front end server.
Both sets of cluster hosts are on the same ether subnet (192.168.1.0/16), but have separate Myrinet switches (not connected).
The main cluster is already up and running SCore use the batch scheduling.
We have 4-8 more compute hosts, and a separate Myrinet switch. We would like to
run Score multi-user on the second cluster.
My understanding is that this is possible if I include 2 pm-myrinet.confs
pm-myrinet.conf for the main cluster
pm-myrinet2.conf for the second cluster
eg in scorehosts.db :
/* PM/Myrinet */
myrinet2k type=myrinet2k \
-firmware:file=/opt/score/share/lanai/lanaiM2k.mcp \
-config:file=/opt/score/etc/pm-myrinet.conf
myrinet2k-2 type=myrinet2k \
-firmware:file=/opt/score/share/lanai/lanaiM2k.mcp \
-config:file=/opt/score/etc/pm-myrinet.2conf

#define MSGBSERV msgbserv=(zeralda.streamline.com:8764)
/* 128 hosts - Main cluster */
comp000.streamline HOST_0 network=myrinet2k,ethernet,shmem0,shmem1 group=_scoreall_,MYRI,ETHER,SHMEM smp=2 MSGBSERV
comp001.streamline HOST_1 network=myrinet2k,ethernet,shmem0,shmem1 group=_scoreall_,MYRI,ETHER,SHMEM smp=2 MSGBSERV
.......

comp127.streamline HOST_127 network=myrinet2k,ethernet,shmem0,shmem1 group=_scoreall_,MYRI,ETHER,SHMEM smp=2 MSGBSERV
/* 4 hosts - development cluster */
comp128.streamline HOST_128 network=myrinet2k-2,ethernet,shmem0,shmem1 group=_scoreall_,MYRI,ETHER,SHMEM smp=2 MSGBSERV
comp129.streamline HOST_129 network=myrinet2k-2,ethernet,shmem0,shmem1 group=_scoreall_,MYRI,ETHER,SHMEM smp=2 MSGBSERV
comp130.streamline HOST_130 network=myrinet2k-2,ethernet,shmem0,shmem1 group=_scoreall_,MYRI,ETHER,SHMEM smp=2 MSGBSERV
comp131.streamline HOST_131 network=myrinet2k-2,ethernet,shmem0,shmem1 group=_scoreall_,MYRI,ETHER,SHMEM smp=2 MSGBSERV
pm-myrinet.conf is the standard conf for a 128 port switch and pm-myrinet.2conf is a conf for 8 port switch.
Is this correct I wonder ?
Thanks,
Nick
