.SH DESCRIPTION
|
||
|
|
.ft R
|
||
|
|
MPI_T_pvar_start starts the performance variable with the handle specified in \fIhandle\fP.

||
|
|
The special value MPI_T_PVAR_ALL_HANDLES can be passed in \fIhandle\fP to start all
|
||
|
|
non-continuous handles in the session specified in \fIsession\fP.
|
||
|
|
|
||
|
|
MPI_T_pvar_stop stops the performance variable with the handle specified in \fIhandle\fP.
|
||
|
|
The special value MPI_T_PVAR_ALL_HANDLES can be passed in \fIhandle\fP to stop all
|
||
|
|
non-continuous handles in the session specified in \fIsession\fP.
|
||
|
|
|
||
|
|
Continuous performance variables can neither be started nor stopped.
