similar to: [LLVMdev] JIT function insertion/creation in multithreaded setting

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.

Hi Edgar, Module and Value are unsafe for concurrent access--even disjoint instances thereof. So you'll need to hold a

Hello, This is probably a bit of a beginner's question but I am new to LLVM I have been examining the possibility of constructing something similar to the JnJVM for a language which supports dynamic class loading. The problem I am having is determining how the JIT system allows for dynamic loading of functions into the JIT. The paper indicates the JnJVM use some sort of callback when the JIT

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

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

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. 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, 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

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,

Hi, I have been looking at the LLVM JIT system as a basis for a project I am working on and had a few beginner's questions which I was hoping someone might be able to answer and which I haven't yet been able to figure out reading the source code. If anyone could provide some help I would appreciate it. 1) How does one go about calling a precompiled function external to the JIT from a JIT

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:

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]]

Hi Everyone, I'm looking for someone who is interested in doing contract work to improve LLVM's support for multithreaded compilers. Specifically, we'd like to support a process with multiple threads hacking on *different* LLVM Module's at the same time in the same address space. At this point, I'm not worried about multiple threads hacking on different parts of a
