🙌 🌐 2 projects using the #ICON model have been nominated for the prestigious Gordon Bell Prize for #ClimateModeling – THE recognition for #HPC:🏅
🔷An ICON simulation of the entire Earth system including the carbon cycle at 1.25 km resolution. It's a scientific & technological milestone!
🔷The Destination Earth Climate Adaptation Digital Twin. It uses simulations from ICON & IFS-FESOM/NEMO & makes climate information directly accessible.

#HPC #supercomputing #Infiniband While trouble-shooting a performance issue on our NDR fabric, where nodes would randomly report high latency and less than expected bandwidth (up to 50% less), I discovered a setting within opensm.conf that configured routing to be randomized vs. distributed/round-robin.... Once I changed the setting (scatter_ports) to the _DEFAULT_, I had immediate and consistent performance improvements. See the before and after images... So, FYI, if your users are reporting random latency and bandwidth issues, double-check your opensm.conf routing. Also, I was using NVIDIA/Mellanox's clusterkit tool.

We're expanding our gallery space in August to set up a Thinking Machines: Connection Machine with an event to celebrate the 40th anniversary. Join as a BOOTSTRAP member to attend the preview and get a behind the scene peek at the CM2's HOST, a Symbolics 3670 LISP machine, as we restore and recover its *LISP (StarLISP) programming system.

I am a sucker for photos of cool #HPC infrastructure, and here is a dense GB200 NVL72 cluster going up somewhere in Canada (I think). Impressive to see this many racks in row; the DC must have facility water which is still uncommon in hyperscale.

Shorter @glennklockwood : Academics care about knowledge creation and sharing, and when building computing systems tend to build them to maximize these values. Commercial enterprises care more about profits and build systems to maximize these. Are these approaches incompatible? No, but the window for overlap in #HPC and #AI for academia and hyperscale commerce was brief and may have closed. Also you have to decide how to spend your time in this world, and he is moving on. mast.hpc.social/@glennklockwoo

Lockwood (@glennklockwood@mast.hpc.social)In the few days I have between jobs, I wanted to share an unvarnished perspective on what I've learned after spending three years working on supercomputing in the cloud.

Embedding training in digital skills in the university curriculum is what will help to spread the use of #HPC in their future.
But also, how the machines have been designed so that it becomes more accessible to new users (snellius vs ARCHER2).
We didn't learn to use the command line in one day.
