Detailed Description

Reallocate data in CPU memory.

Member Function Documentation

transform()

void umpire::op::HostReallocateOperation::transform ( void *  current_ptr, void **  new_ptr, util::AllocationRecord *  current_allocation, util::AllocationRecord *  new_allocation, std::size_t  new_size  )

virtual

Transform length bytes of memory from src_ptr to dst_ptr.

Uses POSIX realloc to reallocate memory in the CPU memory.

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.

Exceptions

util::runtime_error

Reimplemented from umpire::op::MemoryOperation.

apply()

void umpire::op::MemoryOperation::apply ( void *  src_ptr, util::AllocationRecord *  src_allocation, int  val, std::size_t  length  )

virtualinherited

Apply val to the first length bytes of src_ptr.

Parameters

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