similar to: [LLVMdev] Contract position for multithreaded LLVM

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 I want to use LLVM to automatically translate sequential codes to multithreaded codes for execution on multicore processors. How should I start?

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.

Hi yes, I'm asking for any advice, I want to implement multithreaded code generator in LLVM. tnx --- On Tue, 10/5/10, Duncan Sands <baldrick at free.fr> wrote: From: Duncan Sands <baldrick at free.fr> Subject: Re: [LLVMdev] Multithreaded code generation To: llvmdev at cs.uiuc.edu Date: Tuesday, October 5, 2010, 10:50 AM Hi Hamed, > I want to use LLVM to automatically

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. 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

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]]

Since my last question was a bit long, I'll keep this short: What is the "best practice" way to use LLVM JIT in a multithreaded application? I've noticed there can only be one JIT ExecutionEngine present in the application, and putting the engine in a singleton instance doesn't seem to work. Thanks, Eric Yew -------------- next part -------------- An HTML attachment was

I have been looking at the possibility of writing a multithreaded server with the LLVM JIT acting as a key part of the runtime system. In this kind of setting it may entirely be possible for the compiler to be active on to separate threads. I am curious in this sort of situation which entities I would have to protect with a mutex. Is it just certain functions in the Module class? Thanks in

Hey FLAC devs, I managed to hack out a proof-of-concept multithreaded FLAC encoder based on the example libFLAC one. It turned out to be fairly straightforward to get near-linear speedup; I can encode a 636 MB wave file in 6.8s with 8 threads on an 8-core 3.0 GHz Xeon vs. 31.4s with a single thread. Basically I mmap() the input file, divide up the mmap()ed region into nearly equal pieces,

Hello all, I have read the chapter "Writing an LLVM Pass" and noticed that there is a topic "Multithreaded LLVM". However I have no idea about this. I am wondering to know whether the goal of this extension is: 1. Multiple threads handle different modules (Thread : Module = 1 : 1) or 2. Multiple threads handle one module (Thread : Module = N : 1) Thanks a lot --------------

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:

I am using pthreads. I was also wondering what will the llvm IR be for pthreads ?

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

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