[lustre-discuss] Running IBM Power boxes as OSSs?

[Atchley, Scott]

ORNL cleaned up the ppc64le Lustre client code last year. We are running it here on our Summitdev cluster of Power8+Pascal GPUs.

We upstreamed all of the patches as far as I know.

I have it on fairly good authority that Intel bought Whamcloud in order to compete with IBM for future very large (exascale) supercomputer installations. Power architecture is seemingly quite formidable in the supercomputing space so having a combined filesystems and processor architecture is very important for intel if they want to compete in the HPC space.
