Public Member Functions | |
|
DECLARE_DATA_ACCESS DECLARE_DATA_PREF_ACCESS complexScalarFieldTilde | clone () const |
| clone the data (NOTE: assigning complexScalarFieldTilde's makes a new reference to the same data) | |
| complexScalarFieldTildeData (const GridInfo &gInfo, bool onGpu, PrivateTag) | |
| called only by complexScalarFieldTildeData::alloc() | |
| Public Member Functions inherited from FieldData | |
| void | absorbScale () const |
| absorb scale factor into data | |
| void | zero () |
| initialize to zero | |
| void * | data (bool shouldAbsorbScale=true) |
| get a pointer to the actual data (after absorbing the scale factor, unless otherwise specified) | |
| const void * | data (bool shouldAbsorbScale=true) const |
| get a const pointer to the actual data (after absorbing the scale factor, unless otherwise specified) | |
| void * | dataGpu (bool shouldAbsorbScale=true) |
| get a pointer to the actual data (after absorbing the scale factor, unless otherwise specified) | |

| get a const pointer to the actual data (after absorbing the scale factor, unless otherwise specified) | |
| DECLARE_DATA_PREF_ACCESS bool | isOnGpu () 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) |
