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 |
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 |

) |
| | |
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 |

|
|
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 |

) |
| | |
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 |
