Benchmark swap performance on Optane using open source tool like pmbench

Evaluated swap on Linux Kernel 3.10, 4.11, Optane, and Fultondale. The performance was characterised by upgrading 4.11 Kernel through various paging optimisation patches. Results confirmed the hypothesis that with 4.11 with swap optimisation patches, results in significant performance improvement.

Pmbench was also executed with IMDT software and compared against Linux Kernel swap.

Validated IMDT installation guide. Discovered bugs and followed them through fixes.
