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.  

Kernel/Distribution Problem Occurs Problem Does Not Occur
RedHat Enterprise Linux RHEL 8.4 (kernel 4.18.0-305) and older RHEL 8.5 (kernel 4.18.0-348)
SUSE Linux SLES15 SP3 and older SLES15 SP4 beta
Ubuntu Linux Ubuntu releases older than 20.04.03 Ubuntu 20.04.03 (kernel 5.11.0-40-generic #44~20.04.2-ubuntu)*

 

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.
