[LLVMdev] GSoC - feedback for Software Prefetching in LLVM

[Utpal Bora]

Hi,

As the student application portal opens in a day for GSoC 2015, I want to
apply for a project in order to contribute to LLVM community by enhancing
Software Prefetching in LLVM.

I have been studying the feasibility and significance of software
prefetching in modern processors.
I have looked into the current implementation of the same in LLVM for
PowerPC backend by Hal Finkel [1] and am in contact with him in an
introductory level. Currently I am working on his suggestions to fine tune
my proposal.
I am planning to enhance the current implementation for multiple
architectures and also want to extend support to recursive data structures
[2].
I feel that this is doable in the summer which has the potential to improve
performance for scientific applications.
I would like to get the feedback from the community for the topic as a
whole and considering it as part of GSoC.
