OpenACC + MPI resources needed

I wanted to access Class #2: Advanced multi-GPU Programming with MPI and OpenACC (1.5 hours total, 30 min for Q&A) here, but it takes me to the on-demand courses page, and I don’t see this course there. The same thing is true for the other courses present there.

Is there any other resource that introduces MPI with OpenACC? I saw some courses, but they required prior knowledge of MPI. My goal is to run a program that already runs on 1 GPU using OpenACC on multiple GPU clusters. The program processes a grid of cells, which are all completely independent of each other and don’t even need to be synchronized after each timestep which is why dividing this task to run on multiple GPUs would result in a significant performance boost.
