Function Documentation

SanitizerResult SANITIZERAPI sanitizerAlloc ( CUcontext  ctx,
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:
ctx Context for the allocation. If NULL, the current context will be used.
devPtr Pointer to allocated device memory
size Allocation size in bytes

SanitizerResult SANITIZERAPI sanitizerFree ( CUcontext  ctx,
void *  devPtr 
)

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

Note:
Thread-safety: this function is thread safe.
Parameters:
ctx Context for the allocation. If NULL, the current context will be used.
devPtr Device pointer to memory to free

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

Equivalent of cudaMemcpy that can be called within a callback function. The function will return once the copy has completed. If the function is called from a SANITIZER_CB_DOMAIN_LAUNCH callback, only pinned host memory may be used as destination.

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 handle. If NULL, the NULL stream will be used.

SanitizerResult SANITIZERAPI sanitizerMemcpyHostToDeviceAsync ( void *  dst,
void *  src,
size_t  count,
Sanitizer_StreamHandle  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 handle. If NULL, the NULL stream will be used.

SanitizerResult SANITIZERAPI sanitizerMemset ( void *  devPtr,
int  value,
size_t  count,
Sanitizer_StreamHandle  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 handle. If NULL, the NULL stream will be used.
