C e2Bufr2_RX :: two ways. For PUT communication the entry in the buffer |
| 63 |
C :: associated with the source for this receive (determined |
| 64 |
C :: from the opposing_send index) is read. |
| 65 |
C :: For MSG communication the entry in the buffer associated |
| 66 |
C :: with this neighbor of this tile is used as a receive |
| 67 |
C :: location for loading a linear stream of bytes. |
| 68 |
C array1 :: 1rst Component target array that this receive writes to. |

C :: coordinate access to e2Bufr1_RX or to regulate message |
| 78 |
C :: buffering. In PUT communication sender will increment |
| 79 |
C :: handle entry once data is ready in buffer. Receiver will |
| 80 |
C :: decrement handle once data is consumed from buffer. |
| 81 |
C :: For MPI MSG communication MPI_Wait uses handle to check |
| 82 |
C :: Isend has cleared. This is done in routine after receives. |
| 83 |
C commSetting :: Mode of communication used to exchange with this neighbor |
| 84 |
C withSigns :: Flag controlling whether vector field is signed. |
