Pinned toot

Hi everyone! After several years of social media detox, finally decided to join you. I spend most of my time doing physics, and developing (debugging) scientific codes while listening to music.

I’m still fascinated by the efficiency of the MPI_reduce communication patterns. Rolled a custom reduction operation, welded it to a production code and workload seems to be nicely balanced!

Nov. 2020’s top 500 list is already out. The new kid on the block, FZJ’s JUWELS Booster Module (AMD EPYC + NVIDIA A100 / InfiniBand) is the fastest in Germany and also in Europe now (#7 worldwide). HLRS’s Hawk (AMD EPYC / InfiniBand) is another addition to the list at #16, right after the LRZ’s SuperMUC-NG.
See the full list here: top500.org/lists/top500/2020/1

Thanks to @jumboshrimp for the last 2 hours!

I convinced my boss to move our team form the Slack to the Mattermost. :rms:

Next step: persuade the Mattermost system admin to install a Meowmoji pack!

Hi everybody! We're looking for people to broadcast with us. Are you a DJ, radio host, musician, artist or somebody else creative with something in either live or prerecorded audio and/or video format? We need you!

We broadcast on Fridays and Saturdays and are looking to start booking people in either for a one-off or for a regular spot.

It's completely free ofc, and we would be happy to help advertise and promote the work of those that broadcast with us.

Email for more info (on profile).

I mirrored all my github repos on the @codeberg. I have to double-check and archive the github ones after everything is settled down. I hope codeberg to get a proper CI/CD integration, searching tool for the documentations, and RST rendering support soon.

My two cents after staring at random asm codes, and core dump data for a day:

Don’t trust the address sanitizer's crash reports of a thread-unsafe parallel code.

Last week I attended a course on #GPU computing. Specifically for #CUDA devices and its API. Here are the recorded lectures:

And the course material:

It covers different levels, with hands on exercises in #C.

video games 

“Getting over it” is a deep dive in our digital culture which is presented using a video game engine. It is definitely more “game-like” [in its traditional sense] than the likes of “The Beginner's Guide” or “The Stanley Parable”. But the gaming mechanism is there just to create an immersive experience.
