Configure Your System

Intel® oneAPI Rendering Toolkit

If you use the

Intel® oneAPI Rendering Toolkit

(Render Kit) from the Intel® DevCloud, you can skip the prerequisite and configuration sections and start with running a sample application. Intel® DevCloud already has all the

Intel® oneAPI Rendering Toolkit

components installed. See Get Started with Intel DevCloud for oneAPI for details.

To set up your system, you need to:

Install software prerequisites

For best performance, install Intel® Implicit SPMD Program Compiler (Intel® ISPC)

Set environment variables

Install Drivers for GPU, if applicable

Run a sample application to verify your system configuration and get started with the

Intel® oneAPI Rendering Toolkit

Install the software prerequisites and the

Intel® oneAPI Rendering Toolkit

to the default installation directories. Otherwise, you might get an error.

Install Software Prerequisites

Install the following required software:

Microsoft Visual Studio* 2017 15.9.10 or higher.

For Microsoft Windows*, the Visual Studio* C++ Development tools must be installed, including the CMake tools in the Desktop development with C++ workload. Installing the Linux Development with C++ workload will not provide the necessary tools to run all samples. Use the links below to install Visual Studio and CMake.

Visual Studio 2017

Visual Studio 2019

Visual C++ Tools for CMake is installed by default as part of the Desktop Development with C++ workload
.

CMake* 3.12 or higher. Although

the CMake is

not required by the oneAPI tools and toolkits, many oneAPI samples are provided as CMake projects and require CMake to build them. For more information about CMake, refer to CMake.org.

Microsoft Visual Studio 2017 or 2019 installations may already include the CMake 3.12 extension.

Git* for Windows 2.23.0.1 or higher

Optional: A

.ppm

image viewer to open result images (

for example, ImageMagick*, GIMP*, IrfanView*, Adobe® Photoshop®, or nomacs*

)

This guide uses ImageMagick to work with images. For example, it uses the ImageMagick

convert

tool to convert images to the format supported by the Intel® Open Image Denoise.

Intel® Implicit SPMD Program Compiler

Intel® ISPC automatically vectorizes and leverages Intel® Streaming SIMD Extensions, Intel® Advanced Vector Extensions, Intel® Advanced Vector Extensions 2 and Intel® Advanced Vector Extensions 512 instructions.

You can download and install the Intel® ISPC from https://ispc.github.io/.

Intel® ISPC is not included in the

Render Kit

. By default, the

Render Kit

tutorial assets are set to be built with a system compiler.

If you want to use the

rkUtil

superbuild script to build the Intel oneAPI Rendering Toolkit, the Intel® ISPC is downloaded automatically. Using the

rkUtil

superbuild script is recommended for new and returning developers.

Using the Intel® ISPC is recommended to optimize application performance.

Set Environment Variables

To work at a Command Line Interface (CLI), configure components of the oneAPI toolkits using environment variables. Set up your CLI environment by running the

setvars.bat

script from the command line.

You can find the

setvars.bat

script in the root folder of your oneAPI installation, which is typically

C:\Program Files (x86)\Intel\oneAPI\

In this document, the environment variables are set up with this script.

You can also set up the

Render Kit

environment variables per component from a command prompt as follows:

path <install-dir>\ospray\latest\bin;%PATH%

path <install-dir>\ospray_studio\latest\bin;%PATH%

path <install-dir>\embree\latest\bin;%PATH%

path <install-dir>\tbb\latest\redist\intel64\vc_mt;%PATH%

path <install-dir>\openvkl\latest\bin;%PATH%

path <install-dir>\oidn\latest\bin;%PATH%

path <install-dir>\rkcommon\latest\bin;%PATH%

where <install-dir> is the directory where you installed the

Render Kit

. By default, it is

C:\Program Files (x86)\Intel\oneAPI

Option 3: No environment variables

Setting environment variables in the Intel oneAPI Rendering Toolkit simplifies running sample applications. However, they are otherwise not absolutely required for building programs. Deployed applications can be built with a relative

rpath

for the local directory

that allows the dynamic linker to find required libraries.

Build your programs with the

rpath

set similarly or to the local directory.

Stage the desired version of the

oneTBB

runtime libraries along with resulting executables to disambiguate distributions of the

oneTBB

installed on the system.

Developers interested in this deployment are well suited to review the superbuild
CMake script as part of the
