cuda.bindings._v2.driver.stream_write_value64_v2(
intptr_t stream,
uint64_t addr,
uint64_t value,
unsigned int flags,
)#

Write a value to memory.

Write a value to memory. If the memory was registered via cuMemHostRegister(), the device pointer should be obtained with cuMemHostGetDevicePointer(). Support for this can be queried with device_get_attribute() and CU_DEVICE_ATTRIBUTE_CAN_USE_64_BIT_STREAM_MEM_OPS.

Parameters:

  • stream (intptr_t) – The stream to do the write in.

  • addr (uint64_t) – The device address to write to.

  • value (uint64_t) – The value to write.

  • flags (unsigned int) – See CUstreamWriteValue_flags.
