Installation#

Please note that HyPhy is not currently available for Windows.

MP and MPI versions#

HyPhy can be built in two main flavors:

  1. Multi-threaded, assuming the compiler supports OpenMP, otherwise a single-threaded version will be created.
  2. MPI-enabled (for execution on clusters), assuming the build and execution environment proivde MPI support (e.g., through OpenMPI).

Most HyPhy analyses take direct advantage of multi-threading, and a large number of common analyses (e.g. FEL, MEME, FUBAR, GARD) can dramatically benefit from an MPI environment.

Installing with Conda#

conda install -c bioconda hyphy

you may need to add the bioconda channel if you have not already done so:
conda config --add channels bioconda

The Conda package includes both MP and MPI version of HyPhy as HYPHYMP (aliased to hyphy) and HYPHYMPI.

Building from source#

Before continuing, please register and download HyPhy.

Once downloaded, install HyPhy as follows:

  1. Navigate to the newly downloaded/cloned HyPhy directory

    cd hyphy
    
  2. Configure HyPhy using CMake

    cmake .
    
    • By default, HyPhy will be installed into /usr/local/, but it can be installed on any location of your system by specifying a custom installation path:

      cmake -DCMAKE_INSTALL_PREFIX=/location/of/choice .
      
    • If you prefer to use other build systems supported by CMake, such as XCode, configure HyPhy using the generator (-G) switch:

      cmake -G Xcode .
      
    • If would like to specify a particular C/C++ compiler (please note that it must support the C++-14 language standard) for your HyPhy build, use this command:

      cmake . -DCMAKE_CXX_COMPILER=/path/to/C++-compiler -DCMAKE_C_COMPILER=/path/to/C-compiler
      
  3. If you are building HyPhy under MacOS X, you can specify which version of SDK to use, for example:

        cmake -DCMAKE_OSX_SYSROOT=/Developer/SDKs/MacOSX10.9.sdk/ .
    
  4. Build HyPhy by running make with one of the following build targets given below. Note that including the -j flag for make (i.e. make -j <target>) will dramatically speed this step up by taking advantage of multiple processors.

    ## make the HYPHYMP executable:
    make MP
    ## Faster:
    make -j MP
    
    ## make the HYPHYMPI executable:
    make MPI
    
    • MP - build a HyPhy executable (HYPHYMP) using OpenMP to support symmetric multiprocessing. If OpenMP is not installed or not supported by the compiler (e.g. LLVM), the compiled executable will not support multi-threading. You can confirm case by examining the output from running cmake. If openMP is installed, you should see something similar to the following in the output:

      -- Performing Test OpenMP_FLAG_DETECTED
      -- Performing Test OpenMP_FLAG_DETECTED - Success
      -- Try OpenMP CXX flag = [-fopenmp]
      -- Performing Test OpenMP_FLAG_DETECTED
      -- Performing Test OpenMP_FLAG_DETECTED - Success
      -- Found OpenMP: -fopenmp
      
    • MPI - build a HyPhy executable (HYPHYMPI) using the message passing interface MPI to support parallel execution on distributed systems (clusters). An MPI library (e.g., OpenMPI) must be installed and available in your path. You can check if this is the case by examining the output from running cmake. If openMPI is installed, you should see something similar to the following in the output:

          -- Found MPI_C: /opt/scyld/openmpi/1.6.3/gnu/lib/libmpi.so;/usr/lib64/libibverbs.so;/usr/lib64/libdat.so;/usr/lib64/librt.so;/usr/lib64/libnsl.so;/usr/lib64/libutil.so;/usr/lib64/libm.so;/usr/lib64/libtorque.so;/usr/lib64/libm.so;/usr/lib64/libnuma.so;/usr/lib64/librt.so;/usr/lib64/libnsl.so;/usr/lib64/libutil.so;/usr/lib64/libm.so
      
          -- Found MPI_CXX: /opt/scyld/openmpi/1.6.3/gnu/lib/libmpi_cxx.so;/opt/scyld/openmpi/1.6.3/gnu/lib/libmpi.so;/usr/lib64/libibverbs.so;/usr/lib64/libdat.so;/usr/lib64/librt.so;/usr/lib64/libnsl.so;/usr/lib64/libutil.so;/usr/lib64/libm.so;/usr/lib64/libtorque.so;/usr/lib64/libm.so;/usr/lib64/libnuma.so;/usr/lib64/librt.so;/usr/lib64/libnsl.so;/usr/lib64/libutil.so;/usr/lib64/libm.so
      
  5. Finally, install HyPhy on your system with the command

    make install
    

    HyPhy will install either in its default location /usr/local/, or in any custom /location/of/choice/ provided when configuring CMake.

    • HYPHYMP(I) will be installed at /location/of/choice/bin
    • libhyphy_mp.(so/dylib/dll) will be installed at /location/of/choice/lib
    • HyPhy's standard library of scripts/batchfiles will go into /location/of/choice/lib/hyphy

Environment Options#

Should you want to specify the path hyphy searches for its library sources, there are two ways it can be accomplished:

  1. Set LIBPATH argument when calling hyphy. For example, hyphy LIBPATH=/usr/local/lib/hyphy.
  2. Set environment variable HYPHY_LIB_PATH. For example,
export HYPHY_LIB_PATH=/usr/local/lib/hyphy/
hyphy

Notes#

The CMake script will build HyPhy making use of all available features on the host system (e.g. AVX and AVX-2 instructions). If you plan to execute HyPhy in a heterogenous cluster environment where not all nodes may have support for these instructions, you can specify the -DNOAVX=ON flag when you invoke CMake to build to a "lower denominator".

cmake -DNOAVX=ON ./
