Hi, I have seen a lot of problems from people trying to compile R with MKL. So I am writing my experience in case it helps and to ask one question. I installed R-2.8.1.patched in Ubuntu 9.04 (gcc 4.3.3) using MKL 10.1.1.019. I configured correctly (following MKL userguide) with : sudo ./configure --with-blas="-I/opt/intel/mkl/10.1.1.019/include -L/opt/intel/mkl/10.1.1.019/lib/em64t

It appears that Mingw gcc included in RTools is missing a dependent library. If I compile a program with '-lgomp' switch (for OpenMP support), I get a errors about undefined references to functions like '_imp__pthread_mutex_destroy'. Adding the '-static' switch, I get the following error: c:/rtools/mingw/bin/../lib/gcc/mingw32/4.5.0/../../../../mingw32/bin/ld.exe: cannot find -lpt...

Even if there isn't cmake build integration, but assuming an openmp 3.5.0 tar ball will be released for llvm/clang 3.5.0, the flag for openmp support needs to be synced to the library name generated in openmp. Currently, the clang flag -fopenmp flag emits -lgomp whereas the openmp svn currently produces a libiomp5.dylib instead. Also, the clang compiler currently has to be passed an explicitly library path to the location of the libgomp.dylib with -L. While the openmp headers can be found by clang when placed in clang's include directory, the libgomp.d...

...M configure is run. You may also consider to install xdot.py [1] as a more convenient .dot file viewer. xdot.py will used automatically, if it is in the PATH during 'configure' of LLVM) 3. OpenMP: RUN: clang test.c -O3 -Xclang -load -Xclang lib/LLVMPolly.so -mllvm -enable-polly-openmp -lgomp This will automatically OpenMP parallelize your code. (Remember for all this LLVM/Clang/Polly need to be built together such that they are in sync and .so loading works) Cheers Tobi [1] http://code.google.com/p/jrfonseca/wiki/XDot

Hi, I know LLVM provides thread-level automatic parallel support using OpenMP (see  http://blog.llvm.org/2015/05/openmp-support_22.html), but it is not clear for me which of the following is correct? 1. Clang inserts in the source code OpenMP compiler directives, so, it auto-parallelizes the serial source code provided as input or2. Clang can compile manually written parallel source code that uses

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
