Inheritance diagram for ManagedMemory:

Public Member Functions
complex *	data ()
	Return a pointer to the actual data Return a CPU pointer to the actual data, will move data from GPU to CPU if necessary In GPU mode, care must be taken when calling this from multiple cpu threads Only the "GPU Owner" thread may call this when the data is actually on the GPU. Ideally call once from main thread to get data onto the cpu before launching other cpu threads.

const complex *	data () const
	Return a const pointer to the actual data Return a CPU pointer to the actual data, will move data from GPU to CPU if necessary In GPU mode, care must be taken when calling this from multiple cpu threads Only the "GPU Owner" thread may call this when the data is actually on the GPU. Ideally call once from main thread to get data onto the cpu before launching other cpu threads.

size_t	nData () const
	number of data points

bool	isOnGpu () const
	Check where the data is (for #ifdef simplicity exposed even when no GPU_ENABLED)

complex *	dataGpu ()
	Get a gpu data pointer (must be called from GPU owner thread)

const complex *	dataGpu () const
	Get a const gpu data pointer (must be called from GPU owner thread)

complex *	dataPref ()

const complex *	dataPref () const

void	send (int dest, int tag=0) const
	send to another process

void	recv (int src, int tag=0)
	receive from another process

void	bcast (int root=0)
	synchronize across processes (using value on specified root process)

void	allReduce (MPIUtil::ReduceOp op, bool safeMode=false, bool ignoreComplexCheck=false)
	apply all-to-all reduction (see MPIUtil::allReduce). Optionally ignore unsupported operations for complex check.

void	write (const char *fname) const
	binary-write to a file

void	writea (const char *fname) const
	binary-append to a file

void	write (FILE *filep) const
	binary-write toa stream

void	read (const char *fname)
	binary read from a file

void	read (FILE *filep)
	binary read from a stream

void	read_real (const char *fname)
	binary read real-part from file, setting imaginary parts to 0

void	read_real (FILE *filep)
	binary read real-part from stream, setting imaginary parts to 0

void	write_real (const char *fname) const
	binary write real-parts to file

void	write_real (FILE *filep) const
	binary write real-parts to stream

void	dump (const char *fname, bool realPartOnly) const
	write as complex or real-part alone and report discarded imaginary part, if any

void	zero ()
	set all elements to zero

Static Public Member Functions
static void	reportUsage ()
	print memory usage report

Protected Member Functions
void	memFree ()
	Free memory.

void	memInit (string category, size_t nElem, bool onGpu=false)
	Allocate memory.

void	memMove (ManagedMemory &&)
	Steal the other object's data (used for move constructors/assignment)

	ManagedMemory ()
	Initialize a valid state, but don't allocate anything.
