Build for MS Windows

Prerequisites

  • Microsoft Visual Studio 2022 (Community Edition, or better)

  • Intel OneAPI MKL

  • Optional: Git

  • Optional but not generally recommended*: Intel OneAPI TBB

*For most use-cases it is more efficient to parallelize by running multiple CADET simulations instead of parallelizing within one CADET simulation. Including the parallelization code in CADET can lead to performance losses, even if parallelization within CADET is not used. Therefore, we recommend not including the parallelization library TBB unless you know your simulations are large enough to benefit from it.

Assumed directory structure:

|- CADET
|    - src
|    - include
|    - [...]
|    - build

Note that the version numbers of the files and packages below are subject to change and will not always reflect the most recent version.

Visual Studio:

We are using Visual Studio because it is the easiest way to install all required tools, compilers etc. in one step.

  • Download MS Visual Studio

  • Install Visual Studio with the workload “Desktop Developments with C++”

Intel oneAPI Base Toolkit

  • Download the Intel oneAPI Base Toolkit online installer.

  • During the installation, select “Custom Installation” and deselect everything except for:

    • Intel® oneAPI Math Kernel Library (MKL)

    • optional*: Intel® oneAPI Threading Building Blocks (TBB)

Prepare CADET code

  • Clone the CADET source code into a CADET folder:

    • git clone https://github.com/cadet/cadet-core.git CADET

  • Create the directories CADET\build and CADET\install

Build CADET in Visual Studio

  • Open Visual Studio and open the CADET folder

  • Navigate to “Tools” - “Command Line” and open either a “Developer Command Prompt” or “Developer PowerShell”

  • Execute the following command:

    • vcpkg integrate install (this only needs to be run once per PC and will require admin privileges)

  • At the top, where it says DEBUG, select aRELEASE instead

  • Wait for vcpkg to install all the dependencies. The first time this is done on your PC it can take ~15-30 minutes

  • Wait for cmake generation to finish (see output window)

  • From the status bar at the top select Build, Build all

  • Once that finishes, select Build, Install CadetFramework

  • The binaries will be located in CADET\out\install\aRELEASE\bin

Build CADET from the command line

  • Open Visual Studio and select “continue without code”

  • Navigate to “Tools” - “Command Line” and open either a “Developer Command Prompt” or “Developer PowerShell”

  • Execute the following commands:

  • For Command Prompt:

    • cd CADET\build

    • vcpkg integrate install (this only needs to be run once and will require admin privileges)

    • set MKLROOT="C:/Program Files (x86)/Intel/oneAPI/mkl/latest"

    • cmake -DCMAKE_INSTALL_PREFIX=..\out\install\aRELEASE -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE="%VCPKG_ROOT%/scripts/buildsystems/vcpkg.cmake" -DVCPKG_TARGET_TRIPLET=x64-windows-static -DENABLE_STATIC_LINK_LAPACK=ON -DENABLE_STATIC_LINK_DEPS=ON -DBLA_VENDOR=Intel10_64lp_seq --fresh ../

      • If you want to use parallelization and have installed TBB, instead execute set TBBROOT="C:/Program Files (x86)/Intel/oneAPI/tbb/latest" and

      • cmake -DCMAKE_INSTALL_PREFIX=..\out\install\aRELEASE -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE="%VCPKG_ROOT%/scripts/buildsystems/vcpkg.cmake" -DVCPKG_TARGET_TRIPLET=x64-windows-static -DENABLE_STATIC_LINK_LAPACK=ON -DENABLE_STATIC_LINK_DEPS=ON -DBLA_VENDOR=Intel10_64lp --fresh ../

    • msbuild.exe INSTALL.vcxproj /p:Configuration=Release;Platform=x64

  • For PowerShell:

    • cd CADET\build

    • vcpkg integrate install (this only needs to be run once and will require admin privileges)

    • $ENV:MKLROOT = "C:\Program Files (x86)\Intel\oneAPI\mkl\latest"

    • cmake -DCMAKE_INSTALL_PREFIX="..\out\install\aRELEASE" -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE="$ENV:VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake" -DVCPKG_TARGET_TRIPLET=x64-windows-static -DENABLE_STATIC_LINK_LAPACK=ON -DENABLE_STATIC_LINK_DEPS=ON -DBLA_VENDOR=Intel10_64lp_seq "../" --fresh

      • If you want to use parallelization and have installed TBB, instead execute $ENV:TBBROOT = "C:\Program Files (x86)\Intel\oneAPI\tbb\latest" and

      • cmake -DCMAKE_INSTALL_PREFIX="..\out\install\aRELEASE" -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE="$ENV:VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake" -DVCPKG_TARGET_TRIPLET=x64-windows-static -DENABLE_STATIC_LINK_LAPACK=ON -DENABLE_STATIC_LINK_DEPS=ON -DBLA_VENDOR=Intel10_64lp "../" --fresh

    • msbuild.exe INSTALL.vcxproj /p:Configuration="Release;Platform=x64"

  • The binaries will be located in CADET\out\install\aRELEASE\bin

Test build results

  • Navigate to the install location cd CADET\out\install\aRELEASE\bin

  • Run:

    • cadet-cli.exe --version

    • createLWE.exe

    • cadet-cli.exe LWE.h5

  • And confirm the output of the LWE.h5 by opening it in HDF5view or loading it in CADET-Process.

  • If you get no printed return from the first command, run cadet-cli.exe by double-clicking it in the file explorer. This raises error messages that are not raised from a cmd or PowerShell window.
