Based on a NERSC user ticket which inspired #73 @andreasnoack
~@dhiepler can you put the code snippet in a code block (put ```julia
at the beginning and ```
at the end)~
The program looks right to me. To debug this, I'd try to remove the MPIClusterManagers, Distributed
parts and then run the script with mpiexec
like we do in https://github.com/JuliaParallel/Elemental.jl/blob/83089155659739fea1aae476c6fd492b1ee20850/test/runtests.jl#L19
FTR @dhiepler on Cori that would be
srun -n $NUM_RANKS julia path/to/test.jl
I have files each holding 1 column of an array. I would like to create an Elemental.DistMatrix from these files. I would like to load the DistMatrix in parallel. An earlier question was answered by pointing to Elemental/test/lav.jl I made the following program by extracting from lav.jl. It works for a single node and hangs for 2 nodes using mpiexecjl. I am using Julia 1.5 on a 4 core machine running Centos 7.5 Please let me know what is wrong with the program and how to load my column array files in parallel. I intend to eventually run a program using DistMatrix on a computer with hundreds of cores.
Thank you
