Execute the following commands:

  cp conf/pre-commit .git/hooks/

We use inac cmake build-system in combination with different libraries which can be installed using miniconda3. In particular, one can install MKL, IPP and SVML from Intel in a cross-platform portable way with:

$ conda install -c intel mkl-include  # MKL
$ conda install -c intel mkl-static  # MKL
$ conda install -c intel ipp-devel # IPP
$ conda install -c intel icc_rt  # SVML
$ conda install -c numba llvmdev # LLVM

Also, you will need to install LLVM development libraries. You can use conda for that (llvmdev) package, although it is better to use the native libraries in the system (using apt, brew or any other packager of your preference).

• INAC build setup

  • Make sure that you have a configured repository.txt file in ~.inaos\cmake
  • Also you'll need a directory ~\INAOS (can be empty)

• Create a build folder

     mkdir build
     cd build
  

• Invoke CMAKE, we have to define the generator as well as the build-type

     cmake -G"Visual Studio 14 2015 Win64" -DCMAKE_BUILD_TYPE=Debug ..
     cmake -G"Visual Studio 14 2015 Win64" -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
  

• INAC build setup:

  • Make sure that you have a configured repository.txt file in ~/.inaos/cmake
  • Also you'll need a directory ~/INAOS (can be empty)

• Create a build folder:

     mkdir build
     cd build
  

• Invoke CMAKE, we have to define the build-type:

     cmake -DCMAKE_BUILD_TYPE=Debug ..
     cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
  

• If one wants to use the multithreaded version, then add next flag:

     cmake -DCMAKE_BUILD_TYPE=Debug ..
     cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
  

• INAC build setup

  • Make sure that you have a configured repository.txt file in ~/.inaos/cmake
  • Also you'll need a directory ~/INAOS (can be empty)

• MKL setup. For Ubuntu machines, it is best to use Intel's Ubuntu repo (but you can use conda packages described above too):

     wget https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB
     apt-key add GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB
     sudo sh -c 'echo deb https://apt.repos.intel.com/mkl all main > /etc/apt/sources.list.d/intel-mkl.list'
     sudo apt-get update && sudo apt-get install intel-mkl-64bit-2019.X
  

• Create a build folder

     mkdir build
     cd build
  

• Invoke CMAKE, we have to define the build-type, but only two types are supported

     cmake -DCMAKE_BUILD_TYPE=Debug ..
     cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
  

• Some Linux machines (ClearLinux, Gentoo?) require the use of llvm-config utility. You can enforce its use with -DDISABLE_LLVM_CONFIG=False::

     cmake -DCMAKE_BUILD_TYPE=Debug -DDISABLE_LLVM_CONFIG=False ..
     cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -DDISABLE_LLVM_CONFIG=False ..
  

Sometimes it is useful to activate the tracing mechanism for debugging purposes. Example:

$ env INAC_TRACE='*' ./perf_vector_expression  -e 1 -E 2 -M 3 -t 10 -l 0 -c 9 -f 2

• For now only element-wise operations are supported in expression.

• The iron-array library supports disabling SVML optimization by setting a DISABLE_SVML environment variable to any value. This can be useful for debugging purposes.
