similar to: Benchmarking/Profiling tests

I looked at the basic profiling information in the Agile book and around google, but the profiler script that comes with rails doesn''t really seem sufficient. Something like: ruby -r profile <functional test file> Seems a lot more like what I''m trying to get at. But is there any solution that I missed that will give me nice profiling output for functional test

Hi, As a project for a computer performance analysis paper I am taking this semester, I am going to look at the performance of the memory manager in R, with the aim of determining how fast it is and which areas most need improvement. The idea is that I will compare various versions of R, starting with 0.64.2, and then at a few stages in the implementation of the new memory management scheme (of

Hi, I'm having trouble benchmarking disk i/o in my vm's. The data I get seems bogus. I have two centos 6 guests which use a raw image as volume. Each volume is stored on its own physical disk and both disks are the same model. The host system is fedora 15 with the virt-preview repo enabled. The disks for the guests use virtio and caching is set to none. My problem is that I get very

OK, so it looks a lot like a denorm problem. The issue is basically that there are filters that decay exponentially, so when the input suddenly goes to zero, then the filter's output value becomes smaller and

Hi to all LLVMers first of all many thanks for new great LLVM release! now to the question. i was quite happy to look from time to time through regularly built benchmarking html-tables. now i cant easily find it anymore. In contrast to people, who just recently stuck to LLVM, I do know that these benchmarking tests did exist. they don't. i hope audience of ppl like me will be not forgotten

Dear LLVM developers: I am a summer research student at the University of Alberta and I am working on implementing path profiling into LLVM. My work is almost complete; I am currently conducting tests to ensure that the path profiler functions correctly. To provide evidence that the profiler produces accurate results, I have developed a verifier which derives edge profile files (identical to

Anyone have a good tool(s) to use for simulating a bunch of calls? Benchmarking or stress testing? I only need SIP protocol, and do appreciate any replies...I realize I could google it, but I am looking for opinions as well.

Hello, I am trying to profile a function of OpenMx (http://openmx.psyc.virginia.edu) for CPU time. My operating system is OS X 10.10. OpenMx contains C++ and Fortran code. I have read the section regarding profiling compiled code in the manual (https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Profiling-compiled-code). This section and this post (http://blog.fellstat.com/?p=337)

There is code that does this for older versions of LLVM. I believe it is in the giri project in the LLVM SVN repository. I can look into more details when I get back from vacation. Swarup may also be able to provide information on the giri code. -- John T. ________________________________________ From: llvmdev-bounces at cs.uiuc.edu [llvmdev-bounces at cs.uiuc.edu] on behalf of Silky Arora

Hi Jeff, Hi Jean-Marc, I first modified the FPU control word to raise an exception whenever a denormal is used. Then I used the debugger to locate the exceptions and added VERY_SMALLs where they seem to fit well. Although I got CPU usage as low as 10%, I seriously lack knowledge of how things work inside speex. So just changing some code is not the best idea for me. My second attempt was to

Thank you for your suggestions on the patch. If the patch is committed, I would be willing to maintain it, though I am not sure what is all involved or how I am made aware of changes that need to be made. The technical report https://www.cs.ualberta.ca/system/files/tech_report/2010/PreussPathProfLLVM.pdf contains my benchmarks relating to profiling overhead in LLVM. Over the next week I will

I'm not sure if this was intended, but it's going to be a problem for sample profiles. When we compile with -gmlt, the profiler expects to find the line number for all the function headers so that it can compute relative line locations for the profile. The tool that reads the ELF binary is not finding them, so it writes out absolute line numbers, which are impossible to match during the

Hi John and Silky, I can see a copy of 'giri' slicing project branch here http://llvm.org/viewvc/llvm-project/giri/. Though it may be little older, it will work I think. You can look at the code to see how we do the instrumentation. Thanks, Swarup. ________________________________________ From: John Criswell [criswell at illinois.edu] Sent: Tuesday, January 22, 2013 10:29 AM To:
