[Gluster-users] Integration of GPU with glusterfs

[Jim Kinney]

I like the idea immensely. As long as the gpu usage can be specified for server-only, client and server, client and server with a client limit of X. Don't want to take gpu cycles away from machine learning for file IO.

Also must support multiple GPUs and GPU pinning. Really useful for encryption/decryption on client side.
