MetalGPU

Test Metal.jl on ARM M-serie GPUs.

About

Mostly dev sandbox to try out new Metal.jl features on Apple's M2 processors.

⚠️ currently, only Float32 is being supported. For Float64, one could try using a construct from DoubleFloats.jl which may impact performance though.

Performance

Running diffusion_2D_kp.jl on a MacBookAir with M2 chip results in

 Perf. memcopy: time (s) = 0.00929, T_eff (GB/s) = 86.7
 Perf. Laplace: time (s) = 0.00974, T_eff (GB/s) = 82.72 (0.95% of memcopy)
