[mpich-discuss] Information about output of slog2print

Hi,

I used MPE in my MPI application and I converted the output (clog2 file
to slog2 file) and after this I converted again to ascii file using
slog2print.

I want to know if have a documentation which describes the output of
slog2print.

I don't understand the meaning of:

Some stuffs in Header, like as:
  - TreeLeafByteSize;
  - MaxTreeDepth;
  - MaxBufferByteSize;
  -  FBinfo(<integer> @ <integer>)

The categorymap is used to define the elements of MPI (send, recv,
etc..) used in MPI execution. Some info inside of brackets I don't know
the meaning, like as:
  - isUsed;
  - width;
  - info_fmt;
  - vis;
  - search;
  - ratios;
  - count;

And, at least, Slog tree directory, make use of categorymap to provide
the graph of execution.
 - How the tree elements makes the graph? 

I was ask about this because I'm planned to make a bash script to obtain
the informations in a mpi execution.

This is my output logfile of an execution.
