Yes. It’s working well with the mpich-dev/new-op-rma branch. Thanks, Sangmin On Jul 28, 2014, at 9:28 AM, Balaji, Pavan <[email protected]> wrote:

I haven’t tested it with mpich/master.

Hi all,

I encountered the following error when I run the attached MPI RMA code (simplified to reproduce the error) with two nodes. The code works well on a single node (with multiple processes and multiple threads), and had no problem with a single thread per process on two nodes. I used the current MPICH master branch, built it with default configure options, and executed on a linux cluster (MCS Breadboard node 70 and 71, Ubuntu 12.04.4, gcc 4.6.3).

$ mpiexec -f hosts_pthread -n 2 ./rma_get_pthread 4 num_threads: 4 Assertion failed in file src/mpid/ch3/src/ch3u_rma_sync.c at line 5979: MPIU_Object_get_ref(((curr_ptr->request))) >= 0 internal ABORT - process 1

Could someone take a look at it and tell me what I did wrong or whether it is a bug in MPICH?

Thank you, Sangmin
