CUDA randomly freezes when using cudaStreamSynchronize with OpenGL interop

[GulgDev]

It loops fine, however after some time it randomly freezes on cudaStreamSynchronize call after calling cudaGraphicsMapResources on my texture. Here’s my code:

cudaArray_t cuda_array;

cuda_assert(cudaGraphicsMapResources(1, &cudaTexture, stream));
cuda_assert(cudaGraphicsSubResourceGetMappedArray(&cuda_array, cudaTexture, 0, 0));
  
cudaResourceDesc resDesc {};
resDesc.resType = cudaResourceTypeArray;
resDesc.res.array.array = cuda_array;
cudaSurfaceObject_t surface;
cuda_assert(cudaCreateSurfaceObject(&surface, &resDesc));

render<<<map.countChunks(), dim3(CHUNK_SIZE, CHUNK_SIZE), 0, stream>>>(surface, map.getChunks(), step, minX, minY, maxX, maxY);
cuda_assert(cudaPeekAtLastError());

cuda_assert(cudaDestroySurfaceObject(surface));

cuda_assert(cudaGraphicsUnmapResources(1, &cudaTexture, stream));

cuda_assert(cudaStreamSynchronize(stream));

Here’s how I register the texture:

glGenTextures(1, &dataTexture);
glBindTexture(GL_TEXTURE_2D, dataTexture);
  
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
  
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP);

glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, texWidth, texHeight, 0, GL_RGBA, GL_UNSIGNED_BYTE, NULL);

cuda_assert(cudaGraphicsGLRegisterImage(&cudaTexture, dataTexture, GL_TEXTURE_2D, cudaGraphicsRegisterFlagsNone));

I solved the problem. I was writing ouside of the bound texture.
