Hi, I am running Open MPI on Mac OS Catalina and am running into an issue.
- I installed Open MPI and everything seemed to be working fine until a few hours ago. - I make and run with the terminal command: * make && mpiexec --mca shmem posix --oversubscribe -np 8 main.out* - When I do this, I get the following error: *opal_shmem_base_select failed* *--> Returned value -1 instead of OPAL_SUCCESS* - If i remove some of the compiler flags, and run as follows, I get another error: *schmem: posix: file name search - max attempts exceeded.cannot continue with posix.* - In fact, now the program fails to compile at all, and just hangs when I run the make and run command outlined earlier. The program was running correctly earlier today. Could someone please advise? I am new to MPI and would ideally like to develop a lot of skill in using this library for my work. Thanks!
