Function Documentation

SanitizerResult SANITIZERAPI sanitizerAlloc ( void **  devPtr,
size_t  size 
)

Equivalent of cudaMalloc that can be called within a callback function.

Note:
Thread-safety: this function is thread safe.
Parameters:
devPtr Pointer to allocated device memory
size Allocation size in bytes

SanitizerResult SANITIZERAPI sanitizerFree ( void *  devPtr  ) 

Equivalent of cudaFree that can be called within a callback function.

Note:
Thread-safety: this function is thread safe.
Parameters:
devPtr Device pointer to memory to free

SanitizerResult SANITIZERAPI sanitizerMemcpyDeviceToHost ( void *  dst,
void *  src,
size_t  count,
CUstream  stream 
)

Equivalent of cudaMemcpy that can be called within a callback function. The function will return once the copy has completed.

Note:
Thread-safety: this function is thread safe.
Parameters:
dst Destination memory address
src Source memory address
count Size in bytes to copy
stream Stream identifier

SanitizerResult SANITIZERAPI sanitizerMemcpyHostToDeviceAsync ( void *  dst,
void *  src,
size_t  count,
CUstream  stream 
)

Equivalent of cudaMemcpyAsync that can be called within a callback function. The function will return once the pageable buffer has been copied to the staging memory for DMA transfer to device memory, but the DMA to final destination may not have completed.

Note:
Thread-safety: this function is thread safe.
Parameters:
dst Destination memory address
src Source memory address
count Size in bytes to copy
stream Stream identifier

SanitizerResult SANITIZERAPI sanitizerMemset ( void *  devPtr,
int  value,
size_t  count,
CUstream  stream 
)

Equivalent of cudaMemset that can be called within a callback function.

Note:
Thread-safety: this function is thread safe.
Parameters:
devPtr Pointer to device memory
value value to set for each byte of specified memory
count Size in bytes to set
stream Stream identifier
