I think the first line itself (High Performance Computing) reveales that this is a special purpose computer (read - real supercomputer). 512 cores and 24TiB of memory further confirm that. However, this is just a small sized supercomputer (unless that's the limit of resources a user can reserve). I don't know the constraints on this particular SGI machine, but many regular apps cannot be run or rendered useless in HPC domain even when using Linux.
I believe databases like postgres etc. would probably run on this system. I did not choose that route because I wanted to see how far I can go with Awk.
@ketanmaheshwari, which supercomputer is this?
