Why isn't the promise of https://en.wikipedia.org/wiki/Singularity_%28operating_system%29 https://en.wikipedia.org/wiki/Singularity_%28operating_syste... being delved into? Who is pushing the microkernel ideal? Alan Kay has talked about how back in his time one had to do the full stack: hardware to kernelspace to userspace. Why is hardware being developed running Linux instead of an OS tailored to use that hardware?
Maybe it has to do with the Linux kernel being malleable enough to meet these specialized needs. My comment is a bit open ended, there's probably good reasons like the ideas I referenced had underlying issues. Microkernel security isn't really necessary on a supercomputer where anything running on it is more or less trusted code
- gnufx 9y agoI'm afraid security is important on typical HPC systems (at least university ones). I'm horrified to be assured cliinical data on the filesystems is secure when there are trivial privilege escalations on the system. We really do need a microkernel-type capability operating system, though most of what I see is failure to do system management or sane configuration of the batch system.
