Elemental needs `srun` (without `srun`, Elemental won't be able to initialize Cray MPICH)

I don't know all the details at this point, but if I run Elemental (remember, we _don't_ use the one provided by BinaryBuilder -- that one doesn't use Cray MPICH,...

Alas @vchuravy Cray MPICH wants PMI2 :( ``` cori01:~> export LD_LIBRARY_PATH=/usr/lib64/slurmpmi:$LD_LIBRARY_PATH cori01:~> srun -n 2 -C haswell julia pmi_simp.jl srun: job 51995644 queued and waiting for resources srun: job 51995644...

That was what I was thinking. Unfortunately I am not familiar with how to use Elemental, and the docs hosting seems to be broken (and I can't find the docs...

Thanks for the blob -- I'll try to understand it given the docs that I can find. At this point I only understand 10%. Btw, not all of the docs...

Thanks! I'll also look into hosting that locally. FTR: NERSC is at LBNL, and LBNL != LLNL. It's a common misunderstanding, and we are all friends.

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 `...

FTR @dhiepler on Cori that would be ```bash srun -n $NUM_RANKS julia path/to/test.jl ```

I installed Julia using homebrew, and Elemental using the Pkg CLI. When I look for `_dlacpy_` in libEl, I see that it needs `_dlacpy_64_` ``` nm ~/.julia/artifacts/05b4bcf6b87541795cebdcb2ec42f2617af03590/lib/libEl.0.dylib | grep _dlacpy_...

Some more info: I did a system-wide search for all ELF references to `_dlacpy_` (i.e. not excluding the `U` entries from `nm` -- as I did above). The only references...
