Constructor Detail

cudaFuncAttributes

public cudaFuncAttributes()

Default native constructor.

cudaFuncAttributes

public cudaFuncAttributes(long size)

Native array allocator. Access with Pointer.position(long).

cudaFuncAttributes

public cudaFuncAttributes(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

position

public cudaFuncAttributes position(long position)

Overrides:

position in class Pointer

getPointer

public cudaFuncAttributes getPointer(long i)

Overrides:

getPointer in class Pointer

sharedSizeBytes

@Cast(value="size_t")
public long sharedSizeBytes()

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

sharedSizeBytes

public cudaFuncAttributes sharedSizeBytes(long setter)

constSizeBytes

@Cast(value="size_t")
public long constSizeBytes()

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

constSizeBytes

public cudaFuncAttributes constSizeBytes(long setter)

localSizeBytes

@Cast(value="size_t")
public long localSizeBytes()

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

localSizeBytes

public cudaFuncAttributes localSizeBytes(long setter)

maxThreadsPerBlock

public int maxThreadsPerBlock()

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.

maxThreadsPerBlock

public cudaFuncAttributes maxThreadsPerBlock(int setter)

numRegs

public int numRegs()

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

numRegs

public cudaFuncAttributes numRegs(int setter)

ptxVersion

public int ptxVersion()

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.

ptxVersion

public cudaFuncAttributes ptxVersion(int setter)

binaryVersion

public int binaryVersion()

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.

binaryVersion

public cudaFuncAttributes binaryVersion(int setter)

cacheModeCA

public int cacheModeCA()

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

cacheModeCA

public cudaFuncAttributes cacheModeCA(int setter)

maxDynamicSharedSizeBytes

public int maxDynamicSharedSizeBytes()

The maximum size in bytes of dynamic shared memory per block for this function. Any launch must have a dynamic shared memory size smaller than this value.

maxDynamicSharedSizeBytes

public cudaFuncAttributes maxDynamicSharedSizeBytes(int setter)

preferredShmemCarveout

public int preferredShmemCarveout()

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 maximum shared memory. Refer to ::cudaDevAttrMaxSharedMemoryPerMultiprocessor. This is only a hint, and the driver can choose a different ratio if required to execute the function. See ::cudaFuncSetAttribute

preferredShmemCarveout

public cudaFuncAttributes preferredShmemCarveout(int setter)
