A Function-specific attribute type

Variants

MaxThreadsPerBlock = 0

The maximum number of threads per block, beyond which a launch of the function would fail. This number depends on both the function and the device on which the function is currently loaded.

SharedSizeBytes = 1

The size in bytes of statically-allocated shared memory required by this function. This does not include dynamically-allocated shared memory requested by the user at runtime.

ConstSizeBytes = 2

The size in bytes of user-allocated constant memory required by this function.

LocalSizeBytes = 3

The size in bytes of local memory used by each thread of this function.

NumRegs = 4

The number of registers used by each thread of this function.

PtxVersion = 5

The PTX virtual architecture version for which the function was compiled. This value is the major PTX version * 10 + the minor PTX version, so a PTX version 1.3 function would return the value 13. Note that this may return the undefined value of 0 for cubins compiled prior to CUDA 3.0.

BinaryVersion = 6

The binary architecture version for which the function was compiled. This value is the major binary version * 10 + the minor binary version, so a binary version 1.3 function would return the value 13. Note that this will return a value of 10 for legacy cubins that do not have a properly-encoded binary architecture version.

CacheModeCa = 7

The attribute to indicate whether the function has been compiled with user specified option “-Xptxas –dlcm=ca” set .

MaxDynamicSharedSizeBytes = 8

The maximum size in bytes of dynamically-allocated shared memory that can be used by this function. If the user-specified dynamic shared memory size is larger than this value, the launch will fail. See cuFuncSetAttribute

PreferredSharedMemoryCarveout = 9

On devices where the L1 cache and shared memory use the same hardware resources, this sets the shared memory carveout preference, in percent of the total shared memory. Refer to CU_DEVICE_ATTRIBUTE_MAX_SHARED_MEMORY_PER_MULTIPROCESSOR. This is only a hint, and the driver can choose a different ratio if required to execute the function. See cuFuncSetAttribute
