/*
The format:
Each line:
type process task data cycle timestamp [comment]
type - nonnegative integer representing a user-defined event type
process - an integer representing the process in which the event occurred
task - an integer representing a different notion of task. Usually
ignored.
data - an integer representing user data for the event
cycle - an integer representing a time cycle, used to distinguish
between time returned by a timer that "rolls over" during
the run
timestamp - an integer representing (when considered in conjuction
with the cycle number) a time for the event. Upshot treats
the units as microseconds
comment - an optional character string representing user data. Currently
12 character maximum, will soon hopefully be any length (really!)
All events from -100 to -1 are reserved header information events. When
a log is produced, all [-100,-1] events will be moved to the top of the
logfile and have their timestamps set to 0.
All event from -101 and below are reserved system events. This is to
provide some standardization for the logfiles, so various interpreting
programs can glean similar data from the same logfile. All [-101,...)
events will have valid timestamps and will be left in time-sorted
order in the logfile.
Formats for reserved types:
-1 Creation data *not used*
Comment: Creator and date
-2 Number of events in the logfile *not used*
Data: number of events
-3 Number of processors in the run
Data: number of processes
-4 Number of tasks used in the run *not used*
Task: number of tasks
-5 Number of event types used *not used*
Data: number event types
-6 Start time of the run
Timestamp: start time
-7 End time of the run
Timestamp: end time
-8 Number of times the timer cycled
For example, if the timer's units are in microseconds, and it has a
range of 0 - 2^32, and a run lasts 3 hours (range=4294 seconds, 3 hours=
10800 seconds), the timer would have cycled at least twice.
Data: number of timer cycles
-9 Decription of event types *not used*
Data: event type
Comment: Description
-10 printf string for event types *not used*
Data: event type
Comment: printf string
-11 Rollover point
The point at which the timer values 'rollover'
Timestamp: rollover point
-13 State definition
Define a state based on the events that signal the beginning and end
of the state. Also, define what to call the state and what color/
stipple pattern to give it in a graphical visualization tool.
Task: start event
Data: end event
Comment: color:bitmap state name
example: -13 0 3 4 0 0 Green:boxes Rhode Island
An event with type 3 will signify the entrance into a 'Rhode Island'
state. An event wil type 4 will signify the exit of the 'Rhode Island'
state.
States may be overlapped (enter a 'Rhode Island' state while in a
'Wisconsin' state while in a 'Nevada' state), and the state name may
have whitspace in it.
-100 Synchronization event
Sync events are used internally to sychronize timers on the various
processes. They do not appear in the logfiles.
-101 Send message
Represents the sending of a message
Data: process ID of the receiving process
Comment: <message-type tag of message> <size of the message, in bytes>
-102 Receive message
Represents the receiving of a message
Data: process ID of the sending process
Comment: <message-type tag of message> <size of the message, in bytes>
