== Cilk Plus ==
* [http://groups.csail.mit.edu/sct/wiki/index.php?title=Cilk_Plus_Installation_Guide MIT Installation Guide]
* [https://www.cilkplus.org/build-gcc-cilkplus 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 ==
* [https://www.threadingbuildingblocks.org/download TBB Download Page]
* [http://www.inf.ed.ac.uk/teaching/courses/ppls/TBBtutorial.pdf 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

* [https://inside.senecacollege.ca/its/software/index.html Visual Studio 2012 Ultimate] | Select Software Downloads | Go To Visual Studio 2012 Ultimate 1.49GB | Download iso | Burn, if error burn again | Finally, install
* [https://developer.nvidia.com/cuda-downloads 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
** Project -> Properties -> Configuration -> VC++ Directories -> $(CUDA_PATH_INC); $(CUDA_PATH_LIB);
** Project -> Properties -> Configuration -> Linker -> Input -> cudart.lib
