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.

The work took a couple months. The paper took a couple years to get published. Glad this finally made it out into the world!

Vedrørende #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)?

Hello #HPX and #machinelearning #AI folks - I'm looking for someone to do a talk about anything you're doing with oneapi for our meeting up next week?? #iamintel who is up for that??! :D

Last week my co-authors and I published a paper in the Computers & Geosciences journal about "The scalability and composability of flow accumulation algorithms based on asynchronous many-tasks".

The algorithms can be called from Python and scale well over multiple CPU cores and cluster nodes.
