Dear Open MPI users, I am using the following system CentOS release 6.6 Rocks 6.2 I have been trying to install openmpi-3.1.3. After installing it, in the example folder if want to test run I got the following error
I run command mpirun -np 1 hello_c [user@chimera examples]$ mpirun -np 1 hello_c libibverbs: Warning: no userspace device-specific driver found for /sys/class/infiniband_verbs/uverbs0 libibverbs: Warning: no userspace device-specific driver found for /sys/class/infiniband_verbs/uverbs0 -------------------------------------------------------------------------- As of version 3.0.0, the "sm" BTL is no longer available in Open MPI. Efficient, high-speed same-node shared memory communication support in Open MPI is available in the "vader" BTL. To use the vader BTL, you can re-run your job with: mpirun --mca btl vader,self,... your_mpi_application -------------------------------------------------------------------------- -------------------------------------------------------------------------- A requested component was not found, or was unable to be opened. This means that this component is either not installed or is unable to be used on your system (e.g., sometimes this means that shared libraries that the component requires are unable to be found/loaded). Note that Open MPI stopped checking at the first component that it did not find. Host: chimera.pnc.res.in Framework: btl Component: sm -------------------------------------------------------------------------- -------------------------------------------------------------------------- It looks like MPI_INIT failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during MPI_INIT; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer): mca_bml_base_open() failed --> Returned "Not found" (-13) instead of "Success" (0) -------------------------------------------------------------------------- [chimera:04271] *** An error occurred in MPI_Init [chimera:04271] *** reported by process [1310326785,0] [chimera:04271] *** on a NULL communicator [chimera:04271] *** Unknown error [chimera:04271] *** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort, [chimera:04271] *** and potentially your MPI job) I am quite new to it, so please inform me if you need additional information about the system. Any advice is welcomed. Srijan -- SRIJAN CHATTERJEE
