Brendan Higgins recently proposed adding unit tests to the Linux kernel, supplementing other development infrastructure such as perf, autotest and kselftest. The whole issue of testing is very dear to kernel developers' hearts, because Linux sits at the core of the system and often has a very strong stability/security requirement.

Of course, HPC is just one narrow slice of the tech sector, but you can see that same pattern (albeit on different timelines) across the industry. In 2018, it's pretty clear that the cloud model—whether public, private, or hybrid—is the way to go. read more
