No, just changing defaults -- subject to code reviewers approval. As I said before, I prefer to leave library naming to library pros.

It will come on next week. I'd like to give a chance to everyone to raise their objections first.

Jack, Alexey [Bataev] promised to send it for review in a day or two. Then it should be approved by code reviewers, which might take some time. andrey Отправлено с iPad > 12 мая 2015 г., в 21:22, Jack Howarth <howarth.mailing.lists at gmail.com> написал(а): > > Andrey, > Any idea when the patch to enable openmp as the default for > -fopenmp will be posted to

Jack, this is not a problem of this patch, this a problem of your configuration. This patch uses standard clang machinery for locating libiomp5 library.

Hello, I am getting the following error while trying to build a benchmark with a custom function pass: clang -Xclang -fopenmp=libomp -Xclang -load -Xclang my_lib.so file.c error: unknown argument: '-fopenmp=libomp' If I use this instead: clang -Xclang -fopenmp=libomp -Xclang -load -Xclang my_lib.so file.c I get the error: fatal error: 'omp.h' file not found I am not

Dear R experts, recently I started developing a Rcpp package "OpenMPTest". Within that package I want to use OpenMP, as in the following code example: // header file #include <omp.h> using namespace Rcpp ; RcppExport SEXP testOpenMP( SEXP nThreads ) ; // cpp file SEXP testOpenMP( SEXP nThreads ) { BEGIN_RCPP NumericVector numberThreads = NumericVector( nThreads );

Hello! Currently, when a program built without OpenMP (-fopenmp) is trying to dlopen a library, built with the feature, the result is a crash from "bad system call": #0 0x00000008009a223c in ksem_init () from /lib/libc.so.7 #1 0x0000000800998a8f in sem_init () from /lib/libc.so.7 #2 0x00000008011a6537 in omp_get_nested () from /usr/lib/libgomp.so.1 #3

Hi Francesco, This is a huge RFC and I don't think we can discuss all of it at the same time, at least not in a constructive manner. What ends up happening is that people ignore the thread and developers get upset. So, I'll start with the summary, to make sure the overall assumptions in the RFC match the ones I have about it, then we can delve into details. I also think we should not

Hi everybody, I'm trying to develop an R package with Fortran and OpenMP. I wrote a simple hello world but I'm not able to set the number of threads. I found this old email chain <http://r.789695.n4.nabble.com/Set-the-number-of-threads-using-openmp-with-C-td2284685.html> and I tried to set my compile instructions accordingly but i had no luck. *This is my makevars:*

I got this to work on Linux but it is not working on Windows. *My understanding is that this should also work on windows, is that correct?* If so, what should I do? differently? To get it to work on Linux, I modified my R script as follows: #' OpenMP Hello World #' #' @param nthreads The number of threads that you want to use #' @example #' hello(nthreads=2) #' @export

Hi; Both -fplugin-arg-dragonegg-emit-ir and -flto works for creating llvm bitcode that can be run with lli. Thanks to Nick for the suggestion. Now, trying to run an OpenMP hello world program. llvm-gcc -fopenmp p_hello.c -flto -S -o p_hello.ll lli p_hello.ll output: LLVM ERROR: Program used external function 'GOMP_parallel_start' which could not be resolved! I am guessing that I have

Hello, I've written a package that may use OpenMP to speed up computations. OpenMP is supported in recent Gcc versions by using the -fopenmp flag. The problem is that flag crashed gcc versions that do not support OpenMP. So what is the best way for a package to handle this issue. Has someone a configure script that deals with this ? Thanks, Karl [[alternative HTML version deleted]]

Hi all, I'm trying to get the llvm's IR from the source code of Polybench (OMP) https://github.com/cavazos-lab/PolyBench-ACC/tree/master/OpenMP. I noticed a considerable difference between the IR generated using clang -emit-llvm -fopenmp and clang -emit-llvm: * using the -fopenmp flag I get a simplified IR in which I read a single basic block where I can highlight a llvm.memcpy

Hi everybody! Could somebody help me with the following? I'm trying to run a simple Hello World code in openmp using .C function. The C code i have is: #include <omp.h> #include <stdio.h> #include <R.h> void hello_omp(int *n) { int th_id, nthreads; omp_set_num_threads(*n); #pragma omp parallel private(th_id) { th_id = omp_get_thread_num();

Jack, Could you, please, submit a bug report? -- including steps to reproduce (where you got imageMagick sources, how exactly you compiled them, etc) Andrey On Fri, May 1, 2015 at 3:56 PM, Jack Howarth <howarth.mailing.lists at gmail.com> wrote: > > > On Fri, May 1, 2015 at 4:45 AM, Andrey Bokhanko <andreybokhanko at gmail.com> > wrote: >> >> Chandler,

Hi Eli, Attached zipped file, named, "fopenmp_option_support.tar.gz" contains the first patch, along with relevant *test case*. This patch is to support the option "-fopenmp" option in Clang. Following files are changed in this patch. Please start going through this patch, and let me know comments. Meanwhile, I will prepare next patch.
