Installation

Prerequisities

  • An MPI implementation must be installed on your system, preferably with full thread safety, e.g., MPICH.
  • GSL-2.4 or later must be installed on your system.

Installation steps

1. Torc library

A tasking library that allows to write platform-independent code. We assume that the MPI compiler is named mpicc:

    cd lib/torc_lite  
    autoreconf  
    ./configure CC=mpicc --prefix=$HOME/usr/torc  
    make; make install  
    export PATH=$HOME/usr/torc/bin:$PATH

After installing torc, the following flags are available:
torc_cflags
torc_libs

2. GSL library

The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers.

  • Download the latest version of GSL. In a terminal write
    wget http://mirror.switch.ch/ftp/mirror/gnu/gsl/gsl-latest.tar.gz
    tar -xvzf gsl-latest.tar.gz
  • Configure. Set the install folder to be /$HOME/usr. If you want to install in the default diretcory, /usr/local, delete the --prefix=/$HOME/usr.
    ./configure   --prefix=/$HOME/usr
  • Compile and install
    make -j2
    make install

This step will take some time. If you have more available cores, change the 2 in the -j2 to a bigger number.

3. Sampling and Optimization Algorithms

Enter the build directory: 

    cd build

Before compiling, the following need to be checked:

  • gsl-config must be in your PATH (installed by GSL).
  • Name for the MPI compiler in the Makefile, since this can be named differently on different platforms (e.g. CC=cc on Piz Daint).

Compilation options:

build the default option (uses use_torc=0):

    make

build the OpenMP version:

    make use_omp=1

build the TORC-based version:

    make use_torc=1

build the serial version:

    make  use_omp=0  use_torc=0

Test

You can test your installation by doing the following (from root folder):

    cd source/CMAES
    make test
