ISx

I am having problems trying to build the SHMEM port of the ISx benchmark on our Cray XC40 using PrgEnv-gnu (GCC 6.3.0). The error I get is:

I assume this is due to the large static array my_bucket_keys defined in isx.c so I tried to compile with -mcmodel=large, which only shifts the problem to some PMI function, so compilation still fails.

The MPI version of ISx builds just fine. Is this a known problem? Could it be a system configuration issue? Any help is much appreciated.

Known issue. I have seen this once upon a time when i was experimenting with using static vs dynamic arrays. It happened when i tried to run isx with a very large number of keys, and is the reason for my latest pull request (which im assuming you are not using).

Until my pull request is approved, i have the unofficial fix in a branch of my fork: https://github.com/ireed/ISx/branches ('pull-request' branch).

Let me know if that helps.

Who are you waiting on to approve the pull request? I'm not sure who is responsible for ISx curation.

Fix should be merged. Let me know if it works.
