Hi all, Sorry for having been quiet for so long, I have my university exams going on, and will be able to contribute only after the coming Friday. Thanks! -- Sanjoy Das http://playingwithpointers.com

Hi Sanjoy, Here's a version of Banerjee and Wolfe's Exact SIV test: https://sites.google.com/site/parallelizationforllvm/weak-siv-test It assumes you've already filtered out the easy cases handled by ZIV, strong SIV, etc. I'm not confident about my uses of APInt. If you have any comments, I'd love to hear them. Thanks, Preston On Thu, Apr 12,...

Hi, Here is a preliminary (monolithic) version you can comment on. This is still buggy, however, and I'll be testing for and fixing bugs over the next few days. I've used your version of the strong siv test. Thanks! -- Sanjoy Das. http://playingwithpointers.com -------------- next part -------------- A non-text attachment was scrubbed...

Hi Sanjoy, I reworked the code for analyzeStrongSIV to fix a couple of mistakes, plus squeeze all the advantage possible from the symbolic manipulation provided by the SCEVs. It's sketched out here: https://sites.google.com/site/parallelizationforllvm/strong-siv-test Does it makes sense to you? Thanks, Preston On Thu, Apr 5, 2012 at 4:09 PM,...

Hi Sanjoy, Reading through LoopDependenceAnalysis::analyseStrongSIV(), I noticed one problem and one confusion. My confusion related to your naming of the two instructions as A and B. It's consistent all through LoopDependenceAnalysis. I'd prefer something like source and destination, so I can keep track of which is which. It didn't matter so much when...

Gents, I spent some time reading over Sanjoy's patch for LoopDependenceAnalysis. Unfortunately, an early version of these notes escaped; this is the complete review. First off, I agree with his choice to implement the SIV tests. For scientific Fortran, the SIV (and the simpler ZIV) tests cover about 85% of the cases in practice. For C and C++, I expect the percentage will be much higher. Someday we might like to see the general SIV test and handling of MIV subscripts, but we can get a long ways without them. It was...

Hi Hal, Preston! Sorry for the delay! Got busy with some offline work. I've worked on my previous code to calculate direction and distance vectors whenever possible (strong SIV, basically). I think the current code is much clearer and would like your opinions on it. I have attached the patch and also pushed to the github repo I mentioned [1]. Thanks!

It's really too simple to deserve mention... Given a subscript pair, [c1 + a1*i + a2*j] and [c2], we can test for dependence using the RDIV test by rewriting as [c1 + a1*i]

...g simple, with no attempt to take advantage of coupled subscripts. Examine each pair of subscripts in sequence. If a pair is ZIV, we test hoping to prove independence. If we can't, we move on to the next subscript. If a pair is MIV, we ignore it and move on to the next subscript. If a pair is SIV, we check to see if it's something we can handle (strongSIV, weakzeroSIV, ...). If not, skip to next subscript. If we can handle it, compute direction (if StrongSIV, compute distance). Find the appropriate level based on the index variable, turn off the Scalar flag, and intersect the new direc...
