Hi Deepak -- My response was going to be similar, though I was going to wonder whether setting CHPL_COMM_SUBSTRATE to 'portals4' might be sufficient to enable portals 4 support. I think Sung's probably right that this is overly optimistic, though, and expect that you'd need to (at the very least) throw the --enable-portals4 flag to GASNet's configure script (which the Makefile Sung points you to calls).
If that doesn't work, the GASNet documentation that you'll want to refer to is in third-party/gasnet/GASNet-*/portals4-conduit/README as well as the README in the parent directory. As far as I know, you're the first Chapel user to use GASNet over portals4. -Brad On Fri, 11 Jul 2014, Sung-Eun Choi wrote: > Hi Deepak, > > That error happens because the gasnet build failed.
