panic: CUDA_ERROR_INVALID_HANDLE #291

Open godsic opened 3 years ago

godsic commented 3 years ago

@MathieuMoalic reported panic in the following script

Nx := 50
Ny := 501
Nz := 1
dx := 1e-9
dy := 1e-9
dz := 1e-9

setgridsize(Nx, Ny, Nz)
setcellsize(dx, dy, dz)

m = uniform(0, 0, 1)

Msat = 0.81e06
Aex = 1.3e-11
relax()

I've tested on my side against cuda11.2.2 and it indeed panics with the following stack trace

panic: CUDA_ERROR_INVALID_HANDLE
