| 28 | 1 | equemene | <H1>Description</H1> |
| 29 | 1 | equemene | <B>HPL_recv</B> |
| 30 | 1 | equemene | is a simple wrapper around MPI_Recv. Its main purpose is |
| 31 | 1 | equemene | to allow for some experimentation / tuning of this simple routine. |
| 32 | 1 | equemene | Successful completion is indicated by the returned error code |
| 33 | 1 | equemene | HPL_SUCCESS. In the case of messages of length less than or equal to |
| 34 | 1 | equemene | zero, this function returns immediately. |

| 51 | 1 | equemene | </PRE>
|
| 52 | 1 | equemene | <PRE>
|
| 53 | 1 | equemene | RTAG (local input) int |
| 54 | 1 | equemene | On entry, STAG specifies the message tag to be used for this |

|
| 57 | 1 | equemene | <PRE>
|
| 58 | 1 | equemene | COMM (local input) MPI_Comm |
