Awesome, thanks! As per your suggestion, I read the description of these two projects: Advanced Heuristics for Ordering Compiler Optimization Passes Machine learning and compiler optimizations: using inter-procedural analysis to select optimizations and they are amazing! Indeed, they are very close to my interest in autotuning. I didn't see them on the list before. If I choose to focus on

Hello again! Previously, I introduced myself as a prospective GSoC student interested in LLVM. Per Mr. Doerfert suggestion I took a look at two other projects that he said could interest me due to my ongoing research in autotuning. The projects are: Advanced Heuristics for Ordering Compiler Optimization Passes Machine learning and compiler optimizations: using inter-procedural analysis to select

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, I would like to submit two papers that use LLVM to the Related Publications section. Both papers focus on code isolation applied to perform piecewise compiler optimizations. The code isolation process is performed by CERE, an open source tool based on LLVM. The second paper is an extended version of the first one. 1) Piecewise Holistic Autotuning of Compiler and Runtime Parameters

Dear Mihail, I've added these two publications to the publications page. Please review it and let me know if I need to make any changes. In particular, if you have URLs to use for the papers, having those would be greatly appreciated.

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

Hello, I'm Ruijie Fang, currently a 1st-year undergraduate at Princeton University, majoring in Computer Science. I am writing to to express my interest in the Google Summer of Code project: Improve MergeFunctions to incorporate MergeSimilarFunction patches and ThinLTO Support. I've read the LCTES'14 paper and found it quite interesting and comprehensible. I've also went as far

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 list, right now SSH Tunnel / scp is reaches just around 76Mb/s on my E5 Xeon using AES-NI but openssl reaches around 600-700Mb/s using 128aes-cbc cipher. As far as i understand http://www.psc.edu/index.php/hpn-ssh this is due to very small buffers in ssh / scp. Is there any work on this? Like autotuning the buffer size? Are there plans to integrate the hpn patches? Greets, Stefan

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, I am planning to begin a project to explore the space of tuning LLVM internals in an effort to increase performance. I am wondering if anyone can point to me any parameterizations, heuristics, or priorities functions within LLVM that can be tuned/adjusted. So far, I'm considering BranchProbabilityInfo and InlineCost. Does anyone have any other suggestions? Thanks, Robert

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?.

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.

I'm experiencing extremely slow performance when trying to copy files from and to a samba 4 share. I'm using Debian and the Samba 4 SerNet packages and everything is up to date on the client as well as on the server. The connection is made through 100Mbp/s ethernet, but the problem also exists on a local virtual machine that runs on the Debian server. By extremely I mean really abysmal:

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
