Detailed Description

Memset on NVIDIA device memory.

Member Function Documentation

apply()

void umpire::op::CudaMemsetOperation::apply ( void *  src_ptr, util::AllocationRecord *  ptr, int  value, std::size_t  length  )

virtual

Apply val to the first length bytes of src_ptr.

Uses cudaMemset to set first length bytes of src_ptr to value.

Parameters

src_ptr	Pointer to source memory location.
src_allocation	AllocationRecord of source.
val	Value to apply.
length	Number of bytes to modify.

Exceptions

util::runtime_error

Reimplemented from umpire::op::MemoryOperation.

apply_async()

camp::resources::EventProxy< camp::resources::Resource > umpire::op::CudaMemsetOperation::apply_async ( void *  src_ptr, util::AllocationRecord *  ptr, int  value, std::size_t  length, camp::resources::Resource &  ctx  )

virtual

transform()

void umpire::op::MemoryOperation::transform ( void *  src_ptr, void **  dst_ptr, util::AllocationRecord *  src_allocation, util::AllocationRecord *  dst_allocation, std::size_t  length  )

virtualinherited

Transform length bytes of memory from src_ptr to dst_ptr.

Parameters

src_ptr	Pointer to source memory location.
dst_ptr	Pointer to destinatino memory location.
src_allocation	AllocationRecord of source.
dst_allocation	AllocationRecord of destination.
length	Number of bytes to transform.
