Intel Corporation is an American multinational corporation and technology company headquartered in Santa Clara, California, in Silicon Valley.

Intel's Compute-Runtime stack for providing open-source OpenCL and Level Zero compute for their graphics hardware under Linux is out with a new release. Intel Compute-Runtime for open-source OpenCL/L0 on Intel graphics from Broadwell through Xe Graphics can now work under Windows Subsystem for Linux (WSL2). Today's Compute Runtime 21.30.20482 release has the initial code in its user-space compute component for being able to run on WSL(2) for providing Intel GPU compute capabilities within this Linux environment on Windows. 

Besides needing this brand new Intel Compute Runtime release, the GPU para-virtualization support also requires that users be running Windows 11 Insider Preview Build 22000.71. Windows 10 isn't currently supported. In addition to Windows 11, you also need to be running the latest Intel Windows graphics driver package on the host. But with those requirements met, you can then begin to enjoy Intel graphics OpenCL and oneAPI Level Zero support within Windows Subsystem for Linux. 

Intel's competitors in PC chipsets included Advanced Micro Devices (AMD), VIA Technologies, Silicon Integrated Systems, and Nvidia. Intel's competitors in networking include NXP Semiconductors, Infineon,[needs update] Broadcom Limited, Marvell Technology Group and Applied Micro Circuits Corporation, and competitors in flash memory included Spansion, Samsung Electronics, Qimonda, Toshiba, STMicroelectronics, and SK Hynix. The only major competitor in the x86 processor market is AMD, with which Intel has had full cross-licensing agreements since 1976: each partner can use the other's patented technological innovations without charge after a certain time. However, the cross-licensing agreement is canceled in the event of an AMD bankruptcy or takeover.

Some smaller competitors such as VIA Technologies produce low-power x86 processors for small factor computers and portable equipment. However, the advent of such mobile computing devices, in particular, smartphones, has in recent years led to a decline in PC sales. Since over 95% of the world's smartphones currently use processors designed by ARM Holdings, ARM has become a major competitor for Intel's processor market. ARM is also planning to make inroads into the PC and server market.

The latest open-source code for this Intel Compute Runtime 21.30.20482 along with Ubuntu pre-built binary packages can be found via GitHub.


Intel supplies microprocessors for computer system manufacturers such as Lenovo, HP, and Dell. Intel also manufactures motherboard chipsets, network interface controllers and integrated circuits, flash memory, graphics chips, embedded processors and other devices related to communications and computing.
