SubgroupGeMask(3)

Name

SubgroupGeMask - Mask of shader invocations in a subgroup with the same or higher subgroup local invocation ID

Description

SubgroupGeMask

Decorating a variable with the SubgroupGeMask builtin decoration will make that variable contain the subgroup mask of the current subgroup invocation. The bits corresponding to the invocations greater than or equal to SubgroupLocalInvocationId through SubgroupSize-1 are set in the variable decorated with SubgroupGeMask. All other bits are set to zero.

SubgroupGeMaskKHR is an alias of SubgroupGeMask.
