[SCore-users-jp] [SCore-users] 2 swiches, one server.

[Nick Birkett]

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
