Finishing some runtime system work; decided to try a #deskpi #super6c cluster board.
An ITX form factor beowulf cluster is amazing.
#slurm & #nfs worked out of apt.
#ucx, #openmpi, #openshmem, #openpmix, #gasnet, & #hpx needed custom compilation.

OpenMPIをNVIDIAのコンパイラでビルドして、C/C++とFortranのbindingsとコンパイラのラッパーを用意してあげて、こいつをinclude/linkしビルドしたラッパーで別のライブラリを３つをコンパイルし、最終的にPythonで呼び出すやつ。いまOpenMPIのインストールが終わりました。

they wrote their own (velo). as I understand it, the stack looked like
openmpi -> velo -> hypertransport -> network
(raw velo was of course a bit faster without the openmpi overhead)
From the figure you can see IB had a much larger latency penalty

Found the slurm + pmi2 + openmpi apt packages weren't cooperating on the #deskpi. Did a custom build (slurm, pmix, openmpi/openshmem) and all is well provided the jobs are submitted with the correct commands. #LLM helped substantially w/ Q&A + debug

While I should be doing other things, the success of the day is that current OpenMPI on MacOS 14 with Intel OneAPI builds again on my Intel Macbook, if one knows how: github.com/open-mpi/omp... This is thanks to the truly helpful commitment of the OpenMPI developers, especially Jeff Squyres.

There doesn't seem to be a pure Rust implementation of MPI, only bindings to OpenMPI/MPICH
I wonder if that could be a fun thing to do,

a lot of this code was tightly connected in a way that required it to all be built together:
`pybind11` bindings generated from C++ code, `solib` dependencies on OpenMPI, and a bunch of FFI from Haskell to C++ (and vice versa).

Yeah I'm going to figure out install modo 17 tomorrow when it's not 2am.
But also "did you mean rue fromsnap darkdimensions-rue" is funny to me. Like y'know what, yes, every linux dev behind the lack of gui in installing linux programs shall in fact rue this day.
