MPE_Describe_comm_event(4) MPE MPE_Describe_comm_event(4)NAMEMPE_Describe_comm_event - Describe the attributes of an event with
byte informational data in a specified MPI_Comm and on the thread that
the function is invoked.
SYNOPSIS
int MPE_Describe_comm_event( MPI_Comm comm, int eventID,
const char *name, const char *color,
const char *format )
INPUT PARAMETERS
comm - MPI_Comm where this process is part of.
eventID
- event number for the event.
name - name of the event, the maximum length of the NULL-terminated
string is, sizeof(CLOG_DESC), 32.
color - color of the event, the maximum length of the NULL-terminated
string is, sizeof(CLOG_COLOR), 24.
format - printf style %-token format control string for the event, the
maximum length of the NULL-terminated string is,
sizeof(CLOG_FORMAT), 40. If format is NULL, it is equivalent to
calling MPE_Describe_event(). The fortran interface of this rou‐
tine considers the zero-length string, "", and single-blank
string, " ", as NULL.
NOTES
Adds a event definition to the logfile.
This function is threadsafe.
NOTES ON STORAGE FORMAT CONTROL SUPPORT
The format control string is printf like, e.g. "Comment = %s". All the
MPE %-token storage support is provided by SLOG-2. That is whatever
supported by SLOG-2 will be supported by MPE. Currently, the following
is supported.
%s : variable length string, byte buffer size is length of string + 2.
%h : 2-byte integer, printed as decimal integer, byte buffer size is 2.
%d : 4-byte integer, printed as decimal integer, byte buffer size is 4.
%l : 8-byte integer, printed as decimal integer, byte buffer size is 8.
%x : 4-byte integer, printed as hexadecimal integer, byte buffer size
is 4.
%X : 8-byte integer, printed as hexadecimal integer, byte buffer size
is 8.
%e : 4-byte float, printed as decimal float, byte buffer size is 4.
%E : 8-byte float, printed as decimal float, byte buffer size is 8.
