It’s late here!

Thanks for the article, as a former BG/Q admin it’s interesting to see this move by IBM, wonder if anything will come of it.

One minor nit, on a standard production IBM BG/Q these compute nodes ran IBM’s Compute Node Linux which was a cut down OS kernel (no fork() nor execve() for instance) written in a mix of C & C++ and licensed under the Eclipse Public License. Also they had no I/O capabilities other than forwarding any I/O to be done off to the air-cooled I/O nodes which did run a modified Linux kernel and RHEL6.

All the best,
Chris

It was the only homogeniuous architecture in the top of that list before accelerators+technology cached up. Releasing A2 is great as it provides a very effcient and scalable core for free!
