Dear Pavan, Dear Xin, I just downloaded the latest nightly MPICH3 tarball ('mpich-master-v3.1.3-174-gb0f5772f') and compiled it on our IB cluster using the Intel's compilers v15.0: %mpichversion MPICH Version: 3.1.3 MPICH Release date: Wed Nov 12 00:00:34 CST 2014 MPICH Device: ch3:nemesis MPICH configure: --prefix=/nobackup/global/x_vicvy/mpich3-dev.ib --with-device=ch3:nemesis:ib CC=icc CXX=icpc FC=ifort F77=ifort MPICH CC: icc -O2 MPICH CXX: icpc -O2 MPICH F77: ifort -O2 MPICH FC: ifort -O2 Unfortunately, the test-bed code still crashes with the same error message: %mpirun -np 8 ./mpi_tvec2_rma 64 400000 Allocating memory: win_buf=195 (Mb), loc_buf=24 (Mb) Assertion failed in file src/mpid/ch3/src/ch3u_handle_send_req.c at line 71: win_ptr->at_completion_counter >= 0 internal ABORT - process 0 =================================================================================== = BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES = PID 65516 RUNNING AT n3 = EXIT CODE: 1 = CLEANING UP REMAINING PROCESSES = YOU CAN IGNORE THE BELOW CLEANUP MESSAGES =================================================================================== Here I should mention an observed change: the code always crashes with 8 processes, but sometimes it works out with 4 processes (!). However, even with 4 processes you can reproduce the problem by running test-bed several times in a row; i.e.; for i in {1..5}; do mpirun -np 4 ./mpi_tvec2_rma 64 400000; done In order to be sure that the problem is generic, I also fetched the latest commits from mpich/master repo and recompiled MPICH3 on my laptop by using GCC v4.9: %git log --pretty=oneline --abbrev-commit -5 b0f5772 Revert RMA ADI change for req-based RMA operations. eedd51e Delete unused variable. 9107068 Delete no longer needed file. c235c75 Delete no longer used epoch states. f695c96 Bug-fixing: set window state to MPIDI_RMA_NONE when UNLOCK finishes %mpichversion MPICH Version: 3.1.3 MPICH Release date: unreleased development copy MPICH Device: ch3:nemesis MPICH configure: --prefix=/opt/mpi/mpich3-dev/ --no-create --no-recursion MPICH CC: gcc -O2 MPICH CXX: g++ -O2 MPICH F77: gfortran -O2 MPICH FC: gfortran -O2 Even on my laptop, the problem still remains: mpirun -np 4 ./mpi_tvec2_rma 64 400000 Allocating memory: win_buf=195 (Mb), loc_buf=48 (Mb) Allocating memory: win_buf=195 (Mb), loc_buf=48 (Mb) Allocating memory: win_buf=195 (Mb), loc_buf=48 (Mb) Allocating memory: win_buf=195 (Mb), loc_buf=48 (Mb) Assertion failed in file src/mpid/ch3/src/ch3u_handle_send_req.c at line 71: win_ptr->at_completion_counter >= 0 internal ABORT - process 1 ... It would be great if you can check and fix the issue, if needed. With best regards, Victor. P.s.

ssh_config or sshd_config? It should go to the first one.

mpiexec and DISPLAY for remote hosts
by Isaila, Florin D. 11 Nov '14

Hi, I am having troubles running mpiexec (from MPICH 3.1) on remote hosts with xterm (for debugging purposes) from an Ubuntu box. The following command works perfectly in local: mpiexec -n 1 xterm However, if I use a machine file: mpiexec -f macfile -n 1 xterm xterm Xt error: Can't open display: xterm: DISPLAY is not set =================================================================================== = BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES = PID 19225 RUNNING AT thwomp.mcs.anl.gov = EXIT CODE: 1 = CLEANING UP REMAINING PROCESSES = YOU CAN IGNORE THE BELOW CLEANUP MESSAGES =================================================================================== X forwarding is activated: fisaila@howard:bin$ grep X11Forwarding /etc/ssh/sshd_config X11Forwarding yes The following command works: fisaila@howard:bin$ ssh thwomp.mcs.anl.gov xterm Any suggestion how to solve this? Thanks Florin
