search for: intrumentation

Hi, I needed to debug some CUDA code in my project; however, although I used -g when compiling the source code, no source-level information is available in cuda-gdb or cuda-memcheck. Specifically, below is what I did: 1) For a CUDA file a.cu, generate IR files: clang++ -g -emit-llvm --cuda-gpu-arch=sm_35 -c a.cu; 2) Instrument the device code a-cuda-nvptx64-nvidia-cuda-sm_35.bc (generated

My problem is that x and y are two instruments that were thought to be measured the same thing but somehow show a wide confidence interval of the difference between the two intruments.This may be true that these

...O NOT USE) More work-in-progress for comment. More work on the sshd hooks, the implementation in port-solaris.c is still incomplete. I'm interested on feedback about (a) whether or not the interface (see sshaudit.h) is sane and (b) if it's adequate for other systems requiring this kind of intrumentation. ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.

To my knowledge that intrinsic IS generated by frontends like Clang when using _builtin_return_address(), i could be wrong though Zhang > 在 2018年9月5日，10:47，Bekket McClane via llvm-dev <llvm-dev at lists.llvm.org> 写道： > > and

Hello, I wanted to find out more about square polar mapping, cause that whole stuff is a bit tricky - to me - and not so easy to understand. Searching the web did't get me any results, so I wonder what the background of square polar mapping is. Is it derived from some mathematical publications or just the result of a brilliant intuition of a Vorbis programmer ? ;) Thanks. Stoffke

Dear Tobias Grosser, Today I have rebuilt the LLVM-Polly in Release mode. The configuration of my own testing machine is: Intel Pentium Dual CPU T2390(1.86GHz) with 2GB DDR2 memory. I evaluated the Polly using PolyBench and Mediabench. It takes too long time to evaluate the whole LLVM-testsuite, so I just choose the Mediabench from LLVM-testsuite. The preliminary results of Polly compiling

Dear Tobias Grosser, Thank you so much for your kind reply. Your advice is very helpful and inspiring.

Polly seems to be a very promising tool to find out program parallelization based on LLVM

Dear Tobies, Sorry for the late reply. I have checked the experiment and I found some of the data is mismatched because of incorrect manual copy and paste, so I have written a Shell script to automatically collect data. Newest data is listed in the attached file. Tobies, I have made a simple HTML page (attached polly-compiling-overhead.html) to show the experimental data and my plans for this

Is it possible to emulate a unionfs with zfs and zones somehow? My zones are sparse zones and I want to make part of /usr writable within a zone. (/usr/perl5/mumble to be exact) I can''t just mount a writable directory on top of /usr/perl5 because then it hides all the stuff in the global zone. I could repopulate it in the local zone but ugh that is unattractive. I''m hoping

I've put together the first attempt to defining an RDF metadata vocabulary for use with the CD Index/MusicBrainz/OggVorbis. If you care about metadata issues, please take a look at: http://www.cdindex.org/MM I've included a section for video specific stuff, but everything that I originally had in there is being covered by the MM:Contributors section. The Contributors stuff will allow
