GSoC Improving parallelism in various commands

John Gamboa· Mar 24, 2012, 21:06 UTC · lore

Hello...

I'm a Computer Science student and, well, as the topic of this e-mail suggests, I'm planning to submit a project to GSoC on git. I went into the ideas page and found the Git Project Ideas for GSoC page, where I found this idea about improving parallelism in some git commands.

I saw that the idea in the Git Ideas page is very well explained, but, well, I never touched the Git code and I really don't know how difficult it would be, and how many commands are there to be "paralelized". Anyway, I really like parallelism and I found this a very good oportunity to improve my knowledge about it (although I can say I've already played/worked enough to feel confortable on this).

Is there any place where I could find more information on what commands are already parallel? And do anyone have any idea on how many commands could benefit from parallelism? As I said, I never touched the Git code. Would someone recommend me to take a look at some place at first?

Thanks, in advance...

(I tried to send this same e-mail before with some links to the ideas page, but it seems the it was considered a spam and thus it didn't reach its destination. Sorry)

pack-objects, grep, index reading and (soon) index-pack.

See http://thread.gmane.org/gmane.comp.version-control.git/193352/focus=193574.

I'd recommend Documentation/technical/pack-format.txt and sha1_file.c (start with read_sha1_file)
