SAGECal Installation

Cmake Build

Requirements

Ubuntu (tested with 16.04)

    sudo apt-get install software-properties-common
    sudo add-apt-repository -s ppa:kernsuite/kern-3
    sudo apt-add-repository multiverse
    sudo apt-get update
  • Install following packages:
    sudo apt-get install -y git cmake g++ pkg-config libcfitsio-bin libcfitsio-dev libopenblas-base libopenblas-dev wcslib-dev wcslib-tools libglib2.0-dev libcasa-casa2 casacore-dev casacore-data casacore-tools

Other systems

  • Install equivalent packages for your distribution
    • g++
    • cmake
    • git
    • pkg-config
    • openblas
    • libglib2.0-dev
    • follow the instructions at https://github.com/casacore/casacore to install casacore.
    • Additional packages (not essential, but recommended): MPI (openmpi), FFTW

Building

  • Clone the repository
    git clone -b master https://git@github.com/nlesc-dirac/sagecal.git

  • Build SAGECal
    mkdir build && cd build
    cmake .. -DENABLE_CUDA=OFF

OPTIONAL: You can also define a custom casacore path:

    cmake .. -DCASACORE_ROOT_DIR=/opt/soft/casacore/ -DENABLE_CUDA=OFF

OPTIONAL: You can also define a custom paths to everything:

    cmake -DCFITSIO_ROOT_DIR=/cm/shared/package/cfitsio/3380-gcc-4.9.3 -DCASACORE_ROOT_DIR=/cm/shared/package/casacore/v2.3.0-gcc-4.9.3 -DWCSLIB_INCLUDE_DIR=/cm/shared/package/wcslib/5.13-gcc-4.9.3/include -DWCSLIB_LIBRARY=/cm/shared/package/wcslib/5.13-gcc-4.9.3/lib/libwcs.so -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON -DCMAKE_LINKER=/cm/shared/package/gcc/4.9.3/bin/gcc -DCMAKE_CXX_FLAGS=-L/cm/shared/package/cfitsio/3380-gcc-4.9.3/lib -DCMAKE_C_FLAGS=-L/cm/shared/package/cfitsio/3380-gcc-4.9.3/lib ..
Compile with:
    make 
Install at your favorite place
    make DEST=/path/to/sagecal/dir install
  • The sagecal executable can be found in /path/to/sagecal/dir/usr/local/bin, also sagecal-mpi,buildsky and restore might be installed depending on the availability of MPI and WCSLIB/FFTW.

Via Anaconda (WIP)

    conda install -c sagecal=0.6.0

Manual installation

For expert users, and for custom architectures (GPU), the manual install is recommended.

1 Prerequisites:

  • CASACORE http://casacore.googlecode.com/
  • glib http://developer.gnome.org/glib
  • BLAS/LAPACK Highly recommended is OpenBLAS http://www.openblas.net/ Also, to avoid any linking issues (and to get best performance), build OpenBLAS from source and link SAGECal with the static library (libopenblas***.a) and NOT libopenblas***.so
  • Compilers gcc/g++ or Intel icc/icpc
  • If you have NVIDIA GPUs, -- CUDA/CUBLAS/CUSOLVER and nvcc -- NVML Nvidia management library
  • If you are using Intel Xeon Phi MICs. -- Intel MKL and other libraries
  • Get the source for SAGECal
    git clone -b master https://git@github.com/nlesc-dirac/sagecal.git

2 The basic way to build is

1.a) go to ./src/lib/Dirac and ./src/lib/Radio and run make (which will create libdirac.a and libradio.a) 1.b) go to ./src/MS and run make (which will create the executable)

3 Build settings

In ./src/lib/Dirac and ./src/lib/Radio and ./src/MS you MUST edit the Makefiles to suit your system. Some common items to edit are:

  • LAPACK: directory where LAPACK/OpenBLAS is installed
  • GLIBI/GLIBL: include/lib files for glib
  • CASA_LIBDIR/CASA_INCDIR/CASA_LIBS : casacore include/library location and files: Note with new CASACORE might need two include paths, e.g. -I/opt/casacore/include/ -I/opt/casacore/include/casacore
  • CUDAINC/CUDALIB : where CUDA/CUBLAS/CUSOLVER is installed
  • NVML_INC/NVML_LIB : NVML include/lib path
  • NVCFLAGS : flags to pass to nvcc, especially -arch option to match your GPU
  • MKLROOT : for Intel MKL

Example makefiles: Makefile : plain build Makefile.gpu: with GPU support Note: Edit ./lib/Radio/Radio.h MAX_GPU_ID to match the number of available GPUs, e.g., for 2 GPUs, MAX_GPU_ID=1

SAGECAL-MPI Manual Installation

This is for manually installing the distributed version of sagecal (sagecal-mpi), the cmake build will will work for most cases.

1 Prerequsites:

  • Same as for SAGECal.
  • MPI (e.g. OpenMPI)

2 Build ./src/lib/Dirac ./src/lib/Radio as above (using mpicc -DMPI_BUILD)

3 Build ./src/MPI using mpicc++

BUILDSKY Installation

  • See INSTALL in ./src/buildsky

RESTORE Installation

  • See INSTALL in ./src/restore
