Summary | 0018019: ucx library reports erroneous error message | ||||
Description | Problem in CentOS7 stock package ucx-1.5.2-1.el7.x86_64, potentially affecting use of openmpi3-3.1.3-2.el7.x86_64 This error message appears when in use, but it unknown if this is an actual error: sys.c:618 UCX ERROR shmget(size=2097152 flags=0xfb0) for mm_recv_desc failed: Operation not permitted, please check shared memory limits by 'ipcs -l' | ||||
Steps To Reproduce | enter command: ucx_info -d Output always includes this error message: sys.c:618 UCX ERROR shmget(size=2097152 flags=0xfb0) for mm_recv_desc failed: Operation not permitted, please check shared memory limits by 'ipcs -l' | ||||
Additional Information | The subsequent use of the command recommended in the error message, 'ipcs -l' clearly shows there is no problem: ------ Shared Memory Limits -------- max number of segments = 4096 max seg size (kbytes) = 18014398509465599 max total shared memory (kbytes) = 18014398442373116 min seg size (bytes) = 1 This same "UCX ERROR" message also appears while using openmpi library methods from the package 'openmpi3-3.1.3-2.el7.x86_64', but it is unknown (to me) if it might actually affect MPI-related operations. | ||||
