Click an item in the table below for details about that function.

cl_khr_local_int32_base_atomics Optional extensions that implement atomic operations on 32-bit signed and unsigned integers to locations in __local memory.
cl_khr_global_int32_base_atomics Optional extensions that implement atomic operations on 32-bit signed and unsigned integers to locations in __global memory.
cl_khr_local_int32_extended_atomics Optional extensions that implement atomic operations on 32-bit signed and unsigned integers to locations in __local memory.
cl_khr_global_int32_extended_atomics Optional extensions that implement atomic operations on 32-bit signed and unsigned integers to locations in __global memory.
cl_khr_int64_base_atomics Optional extensions that implement atomic operations on 64-bit signed and unsigned integers to locations in __global and __local memory.
cl_khr_int64_extended_atomics Optional extensions that implement atomic operations on 64-bit signed and unsigned integers to locations in __global and __local memory.

Description

These transactions are atomic for the device executing these atomic functions. There is no guarantee of atomicity if the atomic operations to the same memory location are being performed by kernels executing on multiple devices.
