Book Concurrency with Modern C++ ⬆

C++ project Directory concurrency-examples\ contains C++ code examples from the book Concurrency with Modern C++ by Rainer Grimm (Leanpub, 2023).
It also includes several build scripts (batch files, bash scripts, Make scripts) for running the example on a Windows machine.

acquireConsume Example

This example has the following directory structure :

> tree /a /f . | findstr /v /b [A-Z]
|   build.bat
|   build.sh
|   CMakeLists.txt
|   Doxyfile
|   Makefile
\---src
    \---main
        \---cpp
                acquireConsume.cpp

Command build.batrun generates and executes the C++ program target\acquireConsume.exe (with options -bcc, -clang, -gcc, -icx and -msvc to specify a compiler).

> build -verbose -gcc run
Toolset: GCC/GNU Make, Project: acquireConsume
Generate configuration files into directory "build"
Generate executable "acquireConsume.exe"
Execute "build\acquireConsume.exe"

*p2: C++11
data: 2011
atoData: 2014

One may also run command makerun :

> make clean run
"C:/opt/msys64/usr/bin/rm.exe" -rf "build"
"C:/opt/msys64/mingw64/bin/g++.exe"  --std=c++17 -O2 -Wall -Wno-unused-variable  -o build/Release/acquireConsume.exe src/main/cpp/acquireConsume.cpp
build/Release/acquireConsume.exe

fetch_mult Example ▴

This example has the following directory structure :

> tree /a /f . | findstr /v /b [A-Z]
|   build.bat
|   CMakeLists.txt
|   Makefile
\---src
    \---main
        \---cpp
                fetch_mult.cpp

Command build.bat-verbose clean run (with options -clang, -gcc, -icx and -msvc) generates and executes the program build\Release\fetch_mult.exe :

> build -verbose clean run
Delete directory "build"
Toolset: MSVC/MSBuild, Project: fetch_mult
Configuration: Release, Platform: x64
Generate configuration files into directory "build"
Generate executable "fetch_mult.exe"
Execute "build\Release\fetch_mult.exe"

Command makeTOOLSET=icx clean run generates and executes the program build\Release\fetch_mult.exe :

> make TOOLSET=icx clean run
"C:/opt/msys64/usr/bin/rm.exe" -rf "build"
"C:/Program Files (x86)/Intel/oneAPI//compiler/latest/windows/bin/icx.exe"  -Qstd=c++17 -O2 -Fe"build/Release/fetch_mult.exe"  -o build/Release/fetch_mult.exe src/main/cpp/fetch_mult.cpp -link -libpath:"X:/VC/Tools/MSVC/14.36.32532//lib/x64" -libpath:"C:/Program Files (x86)/Windows Kits/10/lib/10.0.22000.0/ucrt/x64" -libpath:"C:/Program Files (x86)/Windows Kits/10/lib/10.0.22000.0/um/x64" -libpath:"C:/Program Files (x86)/Intel/oneAPI//compiler/latest/windows/compiler/lib" -libpath:"C:/Program Files (x86)/Intel/oneAPI//compiler/latest/windows/compiler/lib/intel64"

transitivity Example ▴

This example has the following directory structure :

> tree /a /f . | findstr /v /b [A-Z]
|   build.bat
|   CMakeLists.txt
|   Makefile
\---src
    \---main
        \---cpp
                transitivity.cpp

Command build.bat-verbose clean run (with options -bcc, -clang, -gcc, -icx and -msvc) generates and executes the program build\Release\transitivity.exe :

> build -verbose clean run
Delete directory "build"
Toolset: MSVC/MSBuild, Project: transitivity
Configuration: Release, Platform: x64
Generate configuration files into directory "build"
Generate executable "transitivity.exe"
Execute "build\Release\transitivity.exe"
