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.

Check out Michael Ferguson's new article in the Chapel Blog to learn about how Chapel's design gives it good memory safety properties. The article shows how C, C++, Rust, Python, OpenSHMEM, MPI, and Chapel respond to common programming errors.
