If you are having Errors like the one below. I was trying to use Intel-MPI and MPIEXECJL and I was having this error. I realised that I was getting a bit mixed up on using Intel MPI mpiexec and using mpiexecjl. In the first instance, we use “mpiexecjl”
In my subscription script, we have
.... .... export CC=`which mpicc` export FC=`which mpif90` julia --project -e 'ENV["JULIA_MPI_PATH"]="/usr/local/intel/2018u3/impi/2018.3.222/intel64/bin"; using Pkg; Pkg.build("MPI"; verbose=true)' mpiexecjl -n 16 julia --project HelloWorld.jl .... ....
During the run, we have the following logs……
.... .... + julia --project -e 'ENV["JULIA_MPI_PATH"]="/usr/local/intel/2018u3/impi/2018.3.222/intel64/bin"; using Pkg; Pkg.build("MPI"; verbose=true)' [ Info: using system MPI ┌ Info: Using implementation │ libmpi = "libmpi" │ mpiexec_cmd = `/usr/local/intel/2018u3/impi/2018.3.222/intel64/bin/bin/mpiexec` └ MPI_LIBRARY_VERSION_STRING = "Intel(R) MPI Library 2018 Update 3 for Linux* OS\n" ┌ Info: MPI implementation detected │ impl = IntelMPI::MPIImpl = 4 │ version = v"2018.3.0" └ abi = "MPICH" Building MPI → `~/.julia/packages/MPI/b7MVG/deps/build.log` + date + mpiexecjl -n 16 julia --project HelloWorld.jl ERROR: IOError: could not spawn `/usr/local/intel/2018u3/impi/2018.3.222/intel64/bin/bin/mpiexec -n 16 julia HelloWorld.jl`: no such file or directory (ENOENT) .... ....
Just directly using the mpiexec will solve the issue.
mpiexec -n 16 julia --project HelloWorld.jl
If you use mpiexec and yet face issues like. It may not be exactly the issue with mpiexec, but issues with missing Package (as in my case)
[mpiexec@node1] match_arg (../../utils/args/args.c:254): unrecognized argument project [mpiexec@node1] HYDU_parse_array (../../utils/args/args.c:269): argument matching returned error [mpiexec@node1] parse_args (../../ui/mpich/utils.c:4770): error parsing input array [mpiexec@node1] HYD_uii_mpx_get_parameters (../../ui/mpich/utils.c:5106): unable to parse user arguments
To add Packages, get into Julia. For example,
julia > using Pkg julia > Pkg.add("SharedArrays")
