Nathan, all, Thanks for the quick fix. I can confirm that the behavior with multiple windows is now as expected and as seen in 1.10.3. Best Joseph On 08/25/2016 10:51 PM, Nathan Hjelm wrote: Fixed on master. The fix will be in 2.0.2 but you can apply it to 2.0.0 or 2.0.1: https://github.c

There is a bug in the code that keeps the dynamic regions sorted. Should have it fixed shortly. -Nathan On Aug 25, 2016, at 07:46 AM, Christoph Niethammer wrote: Hello, The Error is not 100% reproducible for me every time but seems to disappear entirely if one excludes -mca osc ^rdma or -mc

Joseph, I also noted the MPI_Info "alloc_shared_noncontig" is unused. I do not know whether this is necessary or not, but if you do want to use it, this should be used once with MPI_Win_create_dynamic Cheers, Gilles On Thursday, August 25, 2016, Gilles Gouaillardet < gilles.gouaillar...@gmail.c
