ctFinishing 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.
The work took a couple months. The paper took a couple years to get published. Glad this finally made it out into the world!
Closing a Source Complexity Gap between Chapel and HPX
A previous case study measured performance vs source-code complexity across multiple languages. The case study identified Chapel and HPX provide similar performance and code complexity. This paper is the result of initial steps toward closing the source-code complexity gap between Chapel and HPX by using a source-to-source compiler. The investigation assesses the single-machine performance of both Chapel and Chplx applications across Arm and x86.

Niels Nielsen, geographerVedrørende #ungdomsuddannelser: Forklar mig venligt hvad den #HPX som #Reformkommissionen foreslår går ud på. Hvordan adskiller den sig fra 2*10.klasse med ekstra timer i sløjd? Hvad kan den som HF ikke allerede kan (ud over måske det ekstra fokus på det praktiske)?
