OpenMP for Mac OS X El Capitan (Torch7)

Written by iassael on . Posted in computing, machine learning, macosx

Having followed a plethora of guides to achieve proper OpenMP support on OS X, this is how it can be done:

  1. Install Homebrew
  2. run “brew update” (don’t skip that 🙂 )
  3. run “brew install clang-omp”
  4. add the following lines to ~/.profile
    export PATH=/usr/local/bin:$PATH

    # CLANG-OMP
    export CC=clang-omp
    export CXX=clang-omp++

    # Brew Libs
    export C_INCLUDE_PATH=/usr/local/include:$C_INCLUDE_PATH
    export CPLUS_INCLUDE_PATH=/usr/local/include:$CPLUS_INCLUDE_PATH
    export LIBRARY_PATH=/usr/local/lib:$LIBRARY_PATH
    export DYLD_LIBRARY_PATH=/usr/local/lib:$DYLD_LIBRARY_PATH

Toch7 Intel MKL not found

Written by iassael on . Posted in computing, machine learning

I am on Mac OS X Yosemite, and although I had installed Intel MKL properly, I was getting a mkl_intel_lp64 not found message when I was trying to install Torch7.

The solution was found by adding the following links to your .profile.

source /opt/intel/composer_xe_2015.3.187/bin/compilervars.sh intel64

and most importantly:

export CMAKE_INCLUDE_PATH=$CMAKE_INCLUDE_PATH:/opt/intel/compilers_and_libraries/mac/include:/opt/intel/mkl/include
export CMAKE_LIBRARY_PATH=$CMAKE_LIBRARY_PATH:/opt/intel/compilers_and_libraries/mac/lib:/opt/intel/mkl/lib

SSH Auto Login – MacOS X

Written by iassael on . Posted in computing

  1. Create your set of keys:
    Start up the Terminal application and run:
    ssh-keygen -t rsassh-keygen will the ask where to store the public key it is about to create. Normally the default suggestion works just fine (~/.ssh/id_rsa.pub). ssh-keygen then ask you to enter a pass phrase. Please use something secure here and please also remember it.
  2. Copy the public key to your SSH server
    Copy the newly created public key to the SSH server(s) you need to auto login into by using your favourite transport method. Please be careful not to overwrite ~/.ssh/authorized_keys if it already exist! This is how I personally copy the key, might not be your preferred method:

    • If authorized_keys exist: 
      cat ~/.ssh/id_rsa.pub | ssh [email protected] "cat - >> ~/.ssh/authorized_keys"
    • If authorized_keys does not exist: 
      scp ~/.ssh/id_rsa.pub [email protected]:~/.ssh/authorized_keys
  3. Optional step: You might consider restricting file access to the file authorized_keys on the SSH server. chmod 0600 ~/.ssh/authorized_keys to even further improve your system security.
