Public Types

typedef complex DataType
 Type of data in container (useful for templating)
 

Public Member Functions

ScalarFieldTilde clone () const
 clone the data (NOTE: assigning ScalarFieldTilde's makes a new reference to the same data)
 
double getGzero () const
 get the G=0 component
 
void setGzero (double Gzero)
 set the G=0 component
 
 ScalarFieldTildeData (const GridInfo &gInfo, bool onGpu, PrivateTag)
 called only by ScalarFieldTildeData::alloc()
 
- Public Member Functions inherited from FieldData< complex >
 FieldData (const GridInfo &gInfo, string category, int nElem, bool onGpu=false)
 
void copyData (const FieldData< complex > &other)
 Copy data and scale (used by clone())
 
void absorbScale () const
 Absorb scale factor into data.
 
complexdata (bool shouldAbsorbScale=true)
 get a pointer to the actual data (after absorbing the scale factor, unless otherwise specified)
 
const complexdata (bool shouldAbsorbScale=true) const
 get a const pointer to the actual data (after absorbing the scale factor, unless otherwise specified)
 
complexdataGpu (bool shouldAbsorbScale=true)
 get a pointer to the actual data (after absorbing the scale factor, unless otherwise specified)
 
const complexdataGpu (bool shouldAbsorbScale=true) const
 get a const pointer to the actual data (after absorbing the scale factor, unless otherwise specified)
 
complexdataPref (bool shouldAbsorbScale=true)
 
const complexdataPref (bool shouldAbsorbScale=true) const
 
void zero ()
 initialize to zero
 
bool isOnGpu () const
 Check where the data is (for #ifdef simplicity exposed even when no GPU_ENABLED)
 
void sendData (const MPIUtil *mpiUtil, int dest, int tag, MPIUtil::Request *request=0) const
 
void recvData (const MPIUtil *mpiUtil, int dest, int tag, MPIUtil::Request *request=0)

void reduceData (const MPIUtil *mpiUtil, MPIUtil::ReduceOp op, int root=0, MPIUtil::Request *request=0)
 

Static Public Member Functions

static ScalarFieldTilde alloc (const GridInfo &gInfo, bool onGpu=false)
 Create reciprocal space data.
 

Additional Inherited Members

- Public Attributes inherited from FieldData< complex >
const int nElem
 number of elements
 
double scale
 overall scale factor of the data array
 
const GridInfogInfo
 simulation grid info
