Re: [OMPI users] Regression: multiple memory regions in dynamic windows

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.com/open-mpi/ompi/commit/e53de7ecbe9f034ab92c832330089cf7065181dc.patch-NathanOn Aug 25, 2016, at 07:31 AM, Joseph Schuchart wrote:Gilles,Thanks for your fast reply. I did some last

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

Hi Joseph, Thanks for reporting this problem. There's an issue now (#2012) https://github.com/open-mpi/ompi/issues/2012 to track this. Howard 2016-08-25 7:44 GMT-06:00 Christoph Niethammer : > Hello, > > The Error is not 100% reproducible for me every time but seems to >

Hi Ralph, I saw the pull request and did a test with v2.0.1rc1, but the problem persists. Any ideas? Thanks, Dr. Jingchao Zhang Holland Computing Center University of Nebraska-Lincoln 402-472-6400 From: users on behalf of

Hello, The Error is not 100% reproducible for me every time but seems to disappear entirely if one excludes -mca osc ^rdma or -mca btl ^openib component. The error is present in 2.0.0 and also 2.0.1rc1. Best Christoph Niethammer - Original Message - From: "Joseph Schuchart"

Re: [OMPI users] Regression: multiple memory regions in dynamic windows

Gilles, Thanks for your fast reply. I did some last minute changes to the example code and didn't fully check the consistency of the output. Also, thanks for pointing out the mistake in computing the neighbor rank. I am attaching a fixed version. Best Joseph On 08/25/2016 03:11 PM, Gilles

Re: [OMPI users] Regression: multiple memory regions in dynamic windows

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 <

Re: [OMPI users] Regression: multiple memory regions in dynamic windows

Joseph, at first glance, there is a memory corruption (!) the first printf should be 0 -> 100, instead of 0 -> 3200 this is very odd because nelems is const, and the compiler might not even allocate this variable. I also noted some counter intuitive stuff in your test program (which still looks

[OMPI users] Regression: multiple memory regions in dynamic windows

All, It seems there is a regression in the handling of dynamic windows between Open MPI 1.10.3 and 2.0.0. I am attaching a test case that works fine with Open MPI 1.8.3 and fail with version 2.0.0 with the following output: === [0] MPI_Get 0 -> 3200 on first memory region [cl3fr1:7342] ***
