Detailed Description

Debugging output.

Author: Th.Eickermann & W.Frings (January 2001)

Print debugging info according to the following environment variables:

SION_DEBUG = filename - print to "filename" or stdout if filename is empty
SION_MASK = Binary mask used to select which messages should be logged
SION_DEBUG_RANK = Specifies for which rank to print the messages
SION_DEBUG_RANK1 = The same as SION_DEBUG_RANK
SION_DEBUG_RANK2 = Specifies a second rank to log

The value for the mask can be calculated by adding the following values:

1 -> sion user function entries and exits
2 -> sion internal function entries and exits
8 -> high frequently called sion user function entries and exits
16 -> high frequently called sion internal function entries and exits
32 -> internal steps of sion internal function
64 -> internal steps of sion user function
128 -> timings (top level)
256 -> timings (low level)
512 -> print filedesc structure contents
2048 -> higher frequently called sion internal function (internal steps)
