Intel® oneAPI Rendering Toolkit: Intel® Implicit SPMD Program Compiler (Intel® ISPC) System Requirements (2022)

Introduction

System requirements for the Intel® SPMD Program Compiler (Intel® ISPC) component of Intel® oneAPI Rendering Toolkit

Version History

2022.3

Intel® oneAPI 2022.3 is validated on Windows and Linux.

• Windows Intel® Graphics Driver, see this article for instructions to download and install.
• Linux General Purpose Intel GPUs (GPGPU) Driver, see this article. Click the one labeled 20220830 for instructions to download and install.

Supported Operating Systems (Host and Target)

NOTE: The following distributions are supported by most components. These OS distributions are tested by Intel or known to work; other distributions may or may not work and are not recommended. If you have questions, access the Intel Community Forums when you need assistance.  If you have Commercial Support, create a support ticket.

Linux* Host

• Ubuntu* LTS 20.04
• Rocky* Linux 8
• Oracle* Linux 8
• Arch Linux*
• Red Hat* Enterprise Linux* (RHEL*) 8
• SUSE Linux Enterprise Server* (SLES) 15 SP3
• Fedora* 35
• Debian* 11

Known Issues

GPU offload applications using extensive multi-threading (>2 threads) may experience hangs or time out which can be recovered only though a hard reset or power cycling of the system for the following Linux Distributions. The issue occurs when reading/writing data to the Intel GPU while making extensive use of multi-threading due to a defect in older Linux kernels.  

Workaround

• Preferred:  Upgrade to a Linux* distribution where the defect has been fixed. Note that the software will run, but a warning message will appear in kernel logs.
• GPU software for Ubuntu 20.04.03 is available now via https://dgpu-docs.intel.com. Note that the software will run, but a warning message will appear in kernel logs. GPU software for RHEL 8.5. will be available in Q1 2022 at the same location. GPU software for SLES15 SP4 will be available shortly after general availability of SLES15 SP4.
• Alternative: Do not use extensive multi-threading in GPU-enabled applications, i.e. keep the number of threads no more than 2. For example, for applications using the oneAPI MPI library, use the single threaded version of the MPI run-time library, rather than the multi-threaded version. Set the environment variable I_MPI_THREAD_SPLIT=0 to use the single threaded version of MPI.

Windows* Host

• Windows* 10
• Windows* 11
• Windows* Server 2022

macOS* Host

• Intel® 64 based systems:
  • macOS* 10.15 Catalina
  • macOS* 11.0, 11.2 Big Sur
  • macOS* 12.0 Monterey
• Apple* M1 based systems:
  • macOS* 12.0 Monterey or higher

Supported Target Hardware Platforms

The following platforms are supported by most software components.

NOTE: Intel® 64 hardware platforms must support at least Intel® Streaming SIMD Extensions 4.2. Full software optimization is implemented for Intel® Advanced Vector Extensions 512. See ark.intel.com to search device capabilities.

• Intel® 64
  • Intel Atom® processors
  • Intel® Core™ processor family
  • Intel® Xeon® processor family
  • Intel® Xeon® Scalable processor family
• ARM
  • Apple* M1

Deprecation

As announced previously, Windows driver support of integrated graphics processors included with 6th - 10th Gen Intel Core Processor and related Intel Atom®, Pentium®, and Celeron® processors is deprecated and has moved to maintenance mode. Only security and critical bug fixes will be updated.

oneAPI tools using existing integrated graphics processor functionality in the aforementioned processors may continue to work, but will no longer be supported. Note that CPU functionality for these processors remains fully supported and unaffected. Please check the oneAPI forum and release notes for further details.
