I want to know how to use cargo-mpirun to run a rust demo on my cluster.

cargo-mpirun is currently hard-coded to use mpiexec, which might not be appropriate on your cluster. In that case, you need to cargo build --bin my-app your executable and then use srun -n 4 target/release/my-app or whatever launcher your cluster uses.

In #9, I added support for MPIEXEC=srun cargo mpirun --bin my-app, which should work, at least for simple cases.
