Description

This extension allows a shader to contain floating-point atomic operations on buffer, workgroup, and image memory. It also advertises the SPIR-V AtomicFloat32AddEXT and AtomicFloat64AddEXT capabilities that allows atomic addition on floating-points numbers. The supported operations include OpAtomicFAddEXT, OpAtomicExchange, OpAtomicLoad and OpAtomicStore.
