Dear all, I have problems for a long time related with mpirun. When I executed mpirun (with my program) I obtained the next error after a while:
. . . . . mlx4: local QP operation err (QPN c00054, WQE index a0000, vendor syndrome 6f, opcode = 5e) [[64826,1],0][btl_openib_component.c:3497:handle_wc] from foner109 to: foner111 error polling LP CQ with status LOCAL QP OPERATION ERROR status number 2 for wr_id af58a8 opcode 128 vendor error 111 qp_idx 3 mpirun has exited due to process rank 0 with PID 51754 on node foner109 exiting improperly. There are two reasons this could occur: 1. this process did not call "init" before exiting, but others in the job did. This can cause a job to hang indefinitely while it waits for all processes to call "init". By rule, if one process calls "init", then ALL processes must call "init" prior to termination. 2. this process called "init", but exited without calling "finalize". By rule, all processes that call "init" MUST call "finalize" prior to exiting or it will be considered an "abnormal termination" This may have caused other processes in the application to be terminated by signals sent by mpirun (as reported here). I am using a cluster (42 nodes, with 20 processors and 64 Gb RAM for each one). I want to use for example only 20 nodes, so I put: salloc -N20 --tasks-per-node=1 --cpus-per-task=20 -p thin(name of the node) mpirun -pernode [my_program] Could you help me to solve this problem? Best Regards, Diego
