Installation Notes

Cilk Plus

• MIT Installation Guide
• Cilk Plus Installation Guide
• Cilk Plus is installed on matrix.senecac.on.ca server and on the matrix partition of the workstations in T2108
  • /usr/local/gcc/gcc-cilk/bin/g++

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

• TBB Download Page
• Intel's tutorial

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

• OpenMP Home Page
• Tim Mattson's Tutorial

Configuration

Linux

• add to gcc compile command -fopenmp

OpenCL

• Khronos Group Home Page

• Intel's OpenCL SDK

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++
