Hello Sir,
I am sorry for being a bit behind my specified schedule, I got a bit busy with
some course related work.
I am attaching a pdf of an initial draft of my project proposal on
'blktrace2pcp' tool. You can also find it online at https://goo.gl/SyDcGW.

Hi Nishant, your proposal looks fine to me. A couple of notes:
- typo in the section header:
2.3 SET UP CONTEST AND WRITE THE BUFFER TO THE ARCHIVE
^^ should be CONTEXT
- regarding pre-faulting: after pre-faulting, we can mlock() the buffer
to prevent it being swapped out. Or we could create the buffer with
mmap(2) and use an anon mapping with MAP_POPULATE|MAP_LOCKED
- for the follow-on project: `visualization tool for blktrace PCP archives':
It sounds as though you will be capable of finishing the libpcp_import
extensions for event data, and the blktrace2pcp tool itself in fairly short
time - so we'll leave the visualization tool fairly open ended. See what you
can come up with - be creative!
Best Regards
