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 the...

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 transfer functions used for memory transfer to the OMPKinds.def file so they are known in the OpenMPOpt.cpp pass. Anothe...

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

Greetings everyone, I am Abhay Raj Singh, a 2nd-year student at NIT Hamirpur, Bharat(India). I am very interested in the project titled "Improve parallelism-aware analyses and optimizations" I would like to apologize for contacting so late I had midterm examination, finished recently. I have taken a course on OpenMP from YouTube which was supported by Intel I have ~4-5 years of

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

Greetings, I'm an LLVM newcomer interested in participating in the next GSoC under the project "Improve parallelism-aware analyses and optimizations". I've already read "Compiler Optimizations for OpenMP" and "Compiler Optimizations for Parallel Programs" both by Doerfert and Finkel. Also, I've watched their two LLVM meeting developers conferences

Thanks for the reply! It sounds like LLVM IR is being considered for optimizations in OpenMP constructs. There seems to be plans regarding improvement of LLVM IR Framework for providing things required for OpenMP / flang(?) Are there any design considerations which contain pros and cons about using the MLIR vs LLVM IR for various OpenMP related optimizations/ transformations? The latest RFC [
