DPC++ Info

Overview

This sample application provides information on all platforms and devices available in DPC++ (similar to clinfo tool).

The following modes are implemented:

• Detailed information on each platform and device (-a):

Supported OS

• Linux
• Windows

Prerequisites

• CMake (version 3.12 and above)
• Git (version 1.8 and above)
• Python (version 2.7 and above)
• Intel(R) oneAPI Base Toolkit

Build and Run

Linux

Run the following commands to build the sample (make sure you have oneAPI DPC++ Compiler in PATH for building):

source <inteloneapi>/setvars.sh
cd <pti>/samples/dpc_info
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make

Use this command line to run the utility:

./dpc_info [-l|-a]

Windows

Use Microsoft* Visual Studio x64 command prompt to run the following commands and build the sample (make sure you have oneAPI DPC++ Compiler in PATH for building):

<inteloneapi>\setvars.bat
cd <pti>\samples\dpc_info
mkdir build
cd build
cmake ..
cmake --build . --config Release

Use this command line to run the application:

cd Release
dpc_info.exe [-l|-a]
