Hi Konstantina, The 1.8 release's numa support is very preliminary and does not include multilocale. If you'd like to try out numa support for multilocale programs, the current trunk supports this better. In addition, without hwloc, things will work, but you won't be taking advantage of any of the numa characteristics of the locale.
As for dataPar-style control, we have not defined any special variable for numa domains yet. We're currently working on better defaults, and I can give you some hints for the settings if you are interested. I'm not sure what you mean below by "cluster of many cores". Are you talking about within a Chapel locale? -- Sung On Thu, Feb 27, 2014 at 01:34:08PM +0000, Konstantina Panagiotopoulou wrote: > 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?
