i have written a simulation using anumerical method, it seems to work fine untill everything cracks and i get the following error in the console:
Cuda error in file ‘2d_cud.cu’ in line 386 : unspecified launch failure.
when i look at the code i see the following:
384 CUDA_SAFE_CALL(cudaMemcpy2DToArray(f2_array, 0, 0, (void *)f2_data, pitch,
385 sizeof(float)*ni, nj,
as you can see,in line 386 i do not see a possible error.
can anyone tell me what does “unspecified lauch failure” means? why am i getting this error?
i apreciate any help.
