A new feature merged this week for the Intel Mesa compiler code for their ANV Vulkan and Iris Gallium3D drivers is support for Stochastic Rounding.
Stochastic Rounding “SRND” is now wired up for the Intel compiler code within Mesa 25.3. The SRND opcode appears to work with upcoming Intel Xe3 graphics hardware.
Stochastic Rounding can help with the accuracy of low-precision numerical computations and is a win for machine learning (AI/ML) and similar fields with low-precision arithmetic.
The SRND opcode and related Intel compiler handling is merged via this MR ahead of Mesa 25.3 stable due out in November.
