legion: Legion: Hang on Summit

I’m trying to run process/node instead of process/gpu for S3D on Summit. It seems to freeze on 4 nodes with 1 process each.

There are stack traces from a debug run with -ll:force_kthreads here: http://sapling.stanford.edu/~seshu/s3d_summit_hang/

About this issue

I rebuilt and hit the assertion. Should be good for you to test.

I guess I did, I had forgotten you were using that copy of S3D. I will switch back to shardrefine with the assertion.
