I’ve got something that works, but it needs to work faster. I’ve tested different methods outside of Julia that can do this much faster, and by comparison with peakflops.jl and a rudimentary calculation of how many opera…

Dear all, I have written a simple Euler stepping algorithm for a particular problem which runs on GPU. The vector y\_current is big (~200\_000) and it is updated like y\_current .= y\_current .+ dt \* RHS. A working example…

Hi Is there a way to calculate vector cross product through ArrayFire.jl in a performant way? The function is not implemented in ArrayFire and the getindex() and setindex!() functions for Julia cause data movement betwe…

Hi! Anyone knows how to implement something equivalent to gfor using the existing ArrayFire wrapper? I guess gfor is not wrapped… Regards,
