Optional extensions that implement atomic operations on 32-bit signed and unsigned integers to locations in __local memory.
An application that wants to use this extension will need to include the #pragma
OPENCL EXTENSION cl_khr_local_int32_extended_atomics : enable
directive in the OpenCL program source.
The atomic functions supported by the cl_khr_local_int32_extended_atomics
extension are described in the following table. All of the functions listed in the following table are performed in one atomic transaction.
Function | Description |
---|---|
int unsigned int |
Read the 32-bit value (referred to as old )
stored at location pointed by p . Compute
min(old , val ) and store minimum value at location
pointed by p . The function returns old .
|
int unsigned int |
Read the 32-bit value (referred to as old )
stored at location pointed by p . Compute
max(old , val ) and store maximum value at location
pointed by p . The function returns old .
|
int unsigned int |
Read the 32-bit value (referred to as old )
stored at location p . Compute
(old & val) and store result at location pointed to
by p . The function returns old .
|
int unsigned int |
Read the 32-bit value (referred to as old )
stored at location p . Compute
(old | val) and store result at location pointed to
by p . The function returns old .
|
int unsigned int |
Read the 32-bit value (referred to as old )
stored at location p . Compute
(old ^ val) and store result at location pointed to
by p . The function returns old .
