Interested in #HPC for clinical (electronic health records) and bioinformatic (sequencing) research.
In perpetual student mode (in 2024 this means lots of #OpenMP, #OpenMPI and #Fortran!)

Associate Professor and Chief of Nephrology Department of Internal Medicine,
Faculty Lead, Hub Research Capacity, Clinical and Translational Science Center, University of New Mexico Health Sciences Center, Albuquerque, NM,USA

You can read long-form thoughts at https://notes.pault.ag/tpl/ where I tried to capture as much as I could into one place.

This is on my blog but I was just the one to put keyboard to markdown here. I am exactly one of many. I hope this represents our thoughts well. It definitely represents mine.

Truth about "thinking" LLMs (screenshot).

I am currently using for a pet project and it has been behaving like this. At least it saves me from the headaches of looking up stuff for the makefile

@ChristosArgyrop @openmp_arb depending on the GPU hardware that you use, single precision execution may utilise tensor cores or produce different residual loop behaviour. With Nvidia compiler, options -Kieee and -gpu=uniform (and not using fastmath) may restore a more coherent behaviour.

@reuterbal @openmp_arb It was just bizarre to see this (actually turning off optimization flags makes this error go away - which apparently has been seen in other contexts). It's most likely a gcc lm issue.

The problem with AGI/ASI and LLMs (thinking or not) is that *linear algebra* (the matrix multiplications from high school),can never be sentient in the same manner as differential equations of the transport processes inside the kidney can produce homeostasis (or make urine).

In an opinion piece in The Conversation, #ACMTuringLaureate Jack Dongarra takes a stand for traditional high-performance computing (#HPC), opining that AI's reliance on HPC necessitates greater focus from the U.S. government.

"US national strategy should include funding new machines and training for people to use them," he writes. Read more: https://theconversation.com/challenges-to-high-performance-computing-threaten-us-innovation-255188

This is really bizarre an error with @openmp_arb (or gcc) when offloading to a #gpu. Double precision version of the code that uses trigonometric functions offload and executes flawlessly. Single precision version of the same code dies with an illegal memory access. I suspect it has to do with the lm library (or rather with sinf cosf). Is there an alternative math library for gpus to try?
