[SCore-users] How can I configure an heterogeneous cluster???

[Augusto Mendes Gomes Junior]

Dear all,

I changed the file scorehosts.db according your suggestion to a cluster with two nodes (SMP=2 and SMP=4), but the following problem occurred:

>> scrun -nodes=2 /opt/score/demo/bin/mandel
   SCore-D 5.4.0 connected.
   <0:0> SCORE: 2 nodes (1x2) ready.
   Error: Can't open display: :0.0
   receive quit message, worker exit

I have tried to enable the DISPLAY with xhost + .

Best Regards,

Augusto Jr.

For example, comp0 has 4 CPUs, and comp1, comp2, comp3, comp4 has 2 CPUs.
and all compute hosts have PM/ethernet device.
The scorehosts.db is following:

/* For PM ethernet */
ethernet	type=ethernet \
	-config:file=/opt/score/etc/pm-ethernet.conf
/* PM/shmem (need maximum CPU per hosts */
shmem0	type=shmem -nodes=0
shmem1	type=shmem -nodes=1
shmem2	type=shmem -nodes=2
shmem3	type=shmem -nodes=3
/* comp0 has 4 CPUs, need 4 PM/shmem devices */
comp0.pccluster.org	msgbserv=server.pccluster.org cpugen=i686 speed=500 \
			smp=4 network=ethernet,shmem0,shmem1.shmem2,shmem3 \
			group=pcc
/* comp1 has 2 CPUs, need only 2 PM/shmem devices */
comp1.pccluster.org	msgbserv=server.pccluster.org cpugen=i686 speed=500 \
			smp=2 network=ethernet,shmem0,shmem1 \
			group=pcc
comp2.pccluster.org	msgbserv=server.pccluster.org cpugen=i686 speed=500 \
			smp=2 network=ethernet,shmem0,shmem1 \
			group=pcc
comp3.pccluster.org	msgbserv=server.pccluster.org cpugen=i686 speed=500 \
			smp=2 network=ethernet,shmem0,shmem1 \
			group=pcc
comp4.pccluster.org	msgbserv=server.pccluster.org cpugen=i686 speed=500 \
			smp=2 network=ethernet,shmem0,shmem1 \
			group=pcc
