Check out our open source Magnetohydrodynamic Algorithm outside a Sphere (MAS) code!

It uses Fortran standard parallelism (with a sprinkle of OpenACC) to run on many GPUs in parallel with NVIDIA's HPC SDK compiler!
Check out its use to model the 2024 total solar eclipse: predsci.com/eclipse2024

Timing results for a small run of the HipFT code (github.com/predsci/hipft) on various CPU and GPUs. The code uses standard #Fortran @fortranlang "do
concurrent" to run in parallel on CPUs and offload to GPUs. For NVIDIA GPUs @NVIDIAHPCDev , unified memory is used, while for Intel GPUs, the use of @OpenMP_ARB Target directives are needed for data movement only.
A neat result here is the use of the new $250 Intel Arc B580 GPU @intelhpc @IntelDevTools @IntelGraphics with its FP64 cores, performing right near where it should based on its memory bandwidth (HipFT is memory bandwidth bound).

Anyone know what the "turbo" key was used for? This is an 80s/90s keyboard. Maybe I can map it to the activation of my GPU environment ;)
