I attached the generated INI file for you to look at.


It is the same value for all parallel runs of GCC+64bit (same value
for all branches)

Yep. Every run, and all of the parallel runs.

The attached mpi_installs.xml is from the trunk+gcc+64bit parallel
scratch directory.

Interesting...

Yes we do. :(

The parallel blocks as we call them are separate scratch directories
in which MTT is running concurrently. Meaning that we have N parallel
block scratch directories each running one instance of MTT. So it is
possible (and highly likely) that when the reporter phase fires all
of the N parallel blocks are firing it about the same time.

Without knowing how the reporter is doing the inserts into the
database I don't think I can help much more than that on debugging.
When the reporter fires for the DB:
  - Does it start a transaction for the connection, do the inserts,
then commit?
  - Does it ship the inserts to the server then allow it to run them,
or does the client do all of the individual inserts?
