Hi Hamed, > I want to use LLVM to automatically translate sequential codes to multithreaded > codes for execution on multicore processors. > How should I start? currently LLVM does not have support for anything like this as far as I know. But perhaps you meant that you want to implement it, and are asking for advice? Ciao, Duncan.

However, if you limit yourself for the moment to loops that fit into the polyhedral model, you can take

Hi, In fact I have some theory on instruction level parallelism( i have a partitioning algorithm), then first of all, i want to generate a multithreaded code from LLVM IR (in assembly level) with a given partitioning. My problem is how can i use a thread library(like Pthread) or OS system calls in LLVM IR to create and manage threads? --- On Tue, 10/5/10, Tobias Grosser <grosser at

Hi I want to use LLVM to automatically generate multithreaded code for execution on multicore processors. My problem is  code generation for multicores and concurrency primitives. Is there any facilities for code generation? How should I start?  Best Regards. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all: I am working on a project using llvm and we need to deal with multithreaded applications. I wanted to know if there was a C front end for llvm that could parse multithreaded applications? I tried llvm-gcc (4.2) and could not get it to work. Is there an extra parameter that I need to pass or something ? Thanks a lot for your help. Regards -- -- Aparna Graduate Student Department

Hi. We have a configuration and audit application called Tripwire Enterprise (7.5) that is running on a Red Enterprise Linux 5.2 server. On this server, we are using winbind (samba version 3.0.33) for authentication (against Windows AD). When we try to run a configuration check on users and permissions we get an error that there is a problematic frame : C [libnss_winbind.so.2+0x129f] . I

Hello all, first post here, I have a multithreaded program that I can't live without. It's a commercial RAW image conversion program called SilkyPix. It works fine under Wine, with a few very minor bugs. But one thing nags me: it's oh so slow... - I have a 64bit quad core with Ubuntu 64. - Wine can use the multicore (or so I've read in the FAQ). - SilkyPix is also

Hello, I want to use some code written for program dependence graph iteration, but this code uses hash_map (#include "llvm/ADT/hash_map") which i think remove from llvm, does anyone know how can i use hsah_map or simply replace that?

I think they'd need to be synced with global counters before function calls as well, since any function

I have been timing a particular model fit using lmer on several different computers and came up with a peculiar result - the model fit is considerably slower on a dual-core Athlon 64 using Goto's multithreaded BLAS than on a single-core processor. Here is the timing on a single-core Athlon 64 3000+ running under today's R-devel with version 0.995-5 of the Matrix package. >

I am interested in being able to encode a single Opus stream using several CPU cores. I get a raw audio input and "opusenc" can transcode it at 1200% speed (Raspberry PI 3B+). It saturates a single CPU core, but the other three are idle. Is out there any project to add multithreading options to "opusenc", or something in that line? Looking around, I have found this:

Hello All Does any know about some opensource multithread-compatible (or concurrent) garbage collector library, if possible suitable for LLVM? (I mean that I want several mutator threads; the collector can be stoptheworld or concurrent ....) H.Boehm's conservative GC is multithread compatible, but seems quite slow (allocation is about the time of a C malloc). And it is well known that

Hi, I was wondering if it is safe to call R functions and/or R BLAS functions from within multithreaded C/C++ code(.Call interface)? It is not in case with MATLAB. I was experimenting using pthreads and OpenMP. Thanks, Rob [[alternative HTML version deleted]]
