We'll Mathematica version 15 was released today. From the release notes:
"Using GPUs is still a fairly fiddly business, with different capabilities on different GPUs and different computer systems. We’re systematically implementing more and more functions for more and more GPU configurations, in each case setting up highly optimized GPU kernels.
And indeed, even beyond GPUs, there are complicated issues in different kinds of support with different hardware. So, for example, in Version 15 we’re adding Method"MUMPS" for LinearSolve for sparse arrays, dramatically speeding up things like large-scale numerical PDE solving for ARM, Apple, etc. processors. "
So, does anyone know whether Mathematica 15 will run on Nvidia DGX Spark (e.g. ARM processor with unified memory + CUDA)?
