Detailed Description

Functions, types, and enums that implement the Sanitizer Memory API.

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 sanitizerAllocEx ( void **  devPtr,
size_t  size,
Sanitizer_MemoryData memoryData 
)

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
memoryData Extra parameters for the memory allocation

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 sanitizerFreeEx ( void *  devPtr,
Sanitizer_MemoryData memoryData 
)

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
memoryData Extra parameters for the memory 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 sanitizerMemcpyDeviceToHostEx ( void *  dst,
void *  src,
size_t  count,
CUstream  stream,
Sanitizer_MemoryData memoryData 
)

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
memoryData Extra parameters for the data copy

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 sanitizerMemcpyHostToDeviceAsyncEx ( void *  dst,
void *  src,
size_t  count,
CUstream  stream,
Sanitizer_MemoryData memoryData 
)

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
memoryData Extra parameters for the data copy

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

SanitizerResult SANITIZERAPI sanitizerMemsetEx ( void *  devPtr,
int  value,
size_t  count,
CUstream  stream,
Sanitizer_MemoryData memoryData 
)

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
memoryData Extra parameters for the data memset


Variable Documentation

Set to 1 if the API should use per-thread stream. This field is only used for memcpy/memset APIs.
