Installation Notes

Cilk Plus

Tips for building from source (tested on Fedora 19)

Works but gets a "Segmentation fault (core dumped)" when testing out w1.cilk.cpp when cilk_for loops > 3 times.

  • download snapshot gcc-2427776 (2013-05-20) (current version on matrix as of 2014-01-17)
  • configure using:
    • /path/to/configure --prefix=/path/to/installation --enable-languages="c,c++" --disable-multilib

Configuration

Linux

  • add to .bash_profile
    • alias gc++="/usr/local/gcc/gcc-cilk/bin/g++ -fcilkplus -ldl -lcilkrts"
    • export LD_LIBRARY_PATH=/path/to/cilkplus-installation/lib:$LD_LIBRARY_PATH
    • source /path/to/tbbvars.sh ia32 -ltbb

TBB

Configuration

Linux

  • copy source script to your home directory
    • cp /usr/local/gcc/tbb/bin/tbbvars.sh
    • change permissions chmod u+x tbbvars.sh
  • long hand notes
    • add to LD_LIBRARY_PATH /usr/local/gcc/tbb41_20130613oss/lib/ia32/gcc4.1
    • needed for dynamic loaded libraries
    • use ldd <binary> to check
    • -v option sends intermediate commands to cerr

OpenMP

Configuration

Linux

  • add to gcc compile command -fopenmp

OpenCL

CUDA

  • Visual Studio 2012 Ultimate | Select Software Downloads | Go To Visual Studio 2012 Ultimate 1.49GB | Download iso | Burn, if error burn again | Finally, install
  • CUDA Downloads
  • Installation add the following environment variables
    • CUDA_PATH - points to the default version
    • CUDA_PATH_INC
    • CUDA_PATH_LIB
  • Visual Studio IDE Settings for .cu files
    • Project -> Build Customizations -> Select CUDA 5.5
    • Source file -> Properites -> Item Type -> CUDA C/C++
    • Project -> Properties -> Configuration -> VC++ Directories -> $(CUDA_PATH_INC); $(CUDA_PATH_LIB);
    • Project -> Properties -> Configuration -> Linker -> Input -> cudart.lib

MPI

Compilation Notes

Cilk Plus

Linux

  • gc++ -o xxx xxx.cpp

TBB

Linux

  • source tbbvars.sh ia32
  • gc++ -o xxx xxx.cpp -ltbb
  • long hand
    • gc++ -I /usr/local/gcc/tbb41_20130613oss/include/ -o xxx -L/usr/local/gcc/tbb41_20130613oss/lib/ia32/gcc4.1/ -ltbb xxx.cpp

OpenCL

  • AMD
    • cl opencl.cpp "%AMDAPPSDKROOT%"lib/x86/OpenCL.lib
    • Environmental Variables
      • INCLUDE add "C:\Program Files\AMD_APP_SDK\2.9\include";
      • LIB add "C:\Program Files\AMD APP SDK\2.9\lib\x86";

CUDA

  • compiling with nvcc
    • Fermi cards - nvcc -code=sm_20 _arch=compute_20
    • nvcc opencl.cpp -lOpenCL
