classical memory bound engineering problems: solving sparse linear system of equations, stencil codes, etc.
> sparse matrix operations.
These are usually memory bound (otherwise they aren't really that sparse), and while most CPUs in the same price category offer similar bandwidth, our benchmarks achieve higher bandwidth.
- bee_rider 5y agoI've had enough luck with Pardiso (my matrices have a nice structure, not too much fill-in after they do METIS or whatever, I guess) that the presence of a free copy of Intel's Pardiso spinoff in MKL is enough to keep me on x86. I don't think this generalizes, though -- the situation with Pardiso, where it is included in Intel's free library but paid for everywhere else (as far as I can tell), is a bit unusual.
