Hello,
I tried to test the new numa node feature. and followed thgese steps
without installing hwloc.
1) export CHPL_LOCALE_MODEL=numa
2)export CHPL_TASKS=qthreads
3)cd $CHPL_HOME
make
4) chpl -o jacobi $CHPL_HOME/examples/programs/jacobi.chpl
And the error I got was:
/chapel-1.8.0/modules/internal/ChapelArray.chpl:148: error: attempt to
dereference nil
My question is: on a cluster of numa nodes do I have to use multilocale
configuration? Something like this?
export CHPL_LOCALE_MODEL=numa;export CHPL_TASKS=qthreads;export
CHPL_COMM=gasnet;gmake;export GASNET_SPAWNFN=S;export SSH_SERVERS="node1
node2";export SSH_CMD=ssh;export SSH_OPTIONS=-x;export
GASNET_ROUTE_OUTPUT=0;source util/setchplenv.bash;
Also, how will I be able to exploit/control the extra cores (sublocales)?
Is there any env variable
"subLocalesPerLocale" or so?
Finally, what's the proposed way to address cluster of manycores(if any)
right now?
Cheers,
Konstantina
