When I run mpirun, I get an error message with the information contained in the graph. How should I fix it?
Any reply will be sincerely appreciated!

Thank you very much for your reply.
I used centos and MPicH-1.1.1. After installing mpich, I tested it and it worked correctly in the attached example file.
Note that when I comment out MPI_Barrier, MPI_Isend still reports an error, as shown in the figure.
I will attach part of my code for your reference. Thanks again!
