Hi there!, As part of my application process to the next GSoC I'm working on the TODO in OpenMPOpt.cpp line 437:     // TODO: We should validate the declaration agains the types we expect.     Link: https://github.com/llvm/llvm-project/blob/master/llvm/lib/Transforms/IPO/OpenMPOpt.cpp#L437 I have a question. When there is a mismatch in the types (return type or argument types) between

Hi Hamilton, I personally don't believe the effort to make the IR "parallelism-aware" is worth it right now. What I propose is something else, see for example https://youtu.be/zfiHaPaoQPc and the OpenMPOpt pass. There are multiple bigger tasks towards better offloading, one of which is described here https://github.com/llvm/llvm-project/issues/180 It might be interesting to add the

Hi there Johannes!, I was checking out the issue (about latency hiding when transferring memory from host to device) you posted about a week ago, but it's not there anymore. Did you remove it?. Thanks. Hamilton. On 21/03/20 10:04 p. m., Hamilton Tobon Mosquera via llvm-dev wrote: > Hi there!, > > Right now I'm starting with the project proposed by Johannes here: >

Ahhh I understand. So I believe the project you posted is still opened. Do you any advice on the question I posted before?. Thank you. On 22/03/20 1:26 p. m., Doerfert, Johannes wrote: > I did not.

Hi Johannes, Yes, I'm highly interested, I already started. It would be nice if you post the details again. I didn't take note of them, I was always looking at the issue in GH. The problem I'm facing right now is this: The first task is identifying OpenMP API calls referred to device memory allocation. I first understood how the compiler driver orchestrates the process of offloading

Hi Johannes, Sorry about the failing tests. I completely forgot about running all of them, I only ran the tests for the openmp ipo transforms. I found the GH issue in cache. I can post it here if you want. I analyzed these runtime calls, __tgt_target_teams_[nowait]. What I don't understand about the problem we want to solve (splitting the memory transfer into issue and wait and legally

Hi Johannes, I've been thinking on how to implement a solution for the problem and I have some questions: 1. You mention in the problem description that the current asynchronous functions can be used, and probably modified. The problem is that those runtime functions with _nowait at the end are not asynchronous. Looking at their implementations, they just wait for other tasks is there

Hi Johannes, In order to create the testcases with the FIXMEs showing how it should look after the transformation, I've been trying to come up with a way of splitting the runtime call __tgt_target_teams based on Silei's recent patch D77005. I like the idea of using its asynchronous version __tgt_target_teams_nowait, but I think we would have to modify it, either to return the

Hello! My name is Emanuel and I am an undergraduate student from Brazil (at the University of São Paulo) wanting to participate in this years GSoC on LLVM. Specifically, on the "Improve parallelism-aware analyses and optimizations" project. I currently do research on autotuning of LLVM IR optimization passes and I am sitting for a class about parallel computing, but I have been studying

Hello, My name is Nader Al Awar, and I am a master's student at UT Austin. I’m interested in working on the "Improve parallelism-aware analyses and optimizations" project as part of GSoC. I looked at the relevant talks papers and I believe that I would be a good fit. Most of my background is in software engineering and testing, but recently my research has focused on applying HPC

Hi Rithik, I CC'd the 2 other mentors and hopefully you'll get answer. Sorry, but I don't know of any other way to help. :/ You may also try to contact them privately.

Hello All, My name is Prakhar Bansal and I am a graduate student in computer engineering at Iowa State University. In my research work, I have worked on Memory access monitoring of an application using the LLVM static analysis framework, where I developed a tracing tool using an LLVM module pass to perform tracing across multiple functions using call graph analysis and also implemented static

Hi Rithik, CodeMoverUtils is not aimed for only loop transformations, it can be used by any transformation which want to move code or check if code is safe to be moved. It can currently do both hoist and sink but require control flow equivalent between the original location and the intended to be moved location. I would like to keep the API decoupled from loop, so other transformation can use it.

Hello, I am an undergrad from India. This summer I'm interested in working on unifying the code motion checks as a GSoC intern with LLVM. I started reading about classical data flow analysis since few months, I see this as a great opportunity to start contributing to LLVM. The idea of unifying all the code motion checks into one place seems very rational and interesting to me. As in the

Hi Hal, > Documentation updates should also be reviewed. Of course, I meant that I'll open a patch in Phabricator. :) I didn't know about code-review patch, thanks. I'll defer the update of developer policy until the other patch is committed so we can have a clearer picture.

Adding a nuw to the add -8 is incorrect. From the perspective of the unsigned math, -8 is treated a very large positive number. The input to the add is [8,13) and adding a large positive number to it wraps around past 0. So that is guaranteed unsigned wrap. On the other hand, a sub nuw 8 would be correct. ~Craig On Sun, Apr 5, 2020 at 3:27 PM Stefanos Baziotis via llvm-dev < llvm-dev at

Is there any way to find if a optimization pass has passed in opt? In clang -fsave-optimzization-record would tell if particular optimization pass has applied or failed. Is there similar functionality in opt? Regards, Nethish. -------------- next part -------------- An HTML attachment was scrubbed... URL:
