 I have been using the 'tdb' command with a PAR file on our Meiko Computing
Surface recently.  Below is the example

par
        processor 0 test -s 5
        processor 1 test 5
endpar

 The programs are written in 'C' and use the CStools to communicate. I can only
monitor one program at once by using tdb. The documantation suggests that it is
possible to run one tdb per transputer, i.e. can monitor both of my programs
communicating with each other on two tdb's. I can not seem to get this to work.

 Could anybody who has come across this please cast some light on it. Is it
possible ? If so how ?

Thanks 
Barry Evans

Hi Barry,
 
I've been trying to do the very thing you ask for some time now and am still
in the same position that you are...
 
I think that it isn't currently possible to run multiple tdb's on the same
job as they are all one unix job. This means that you can't get subsequent
tdb's into it.
 
Maybe you could fork a new tdb off of the old one (I don't know)...
 
If you get an answer to this I sure would like to know, it's a real pain
trying to debug a parallel program and only being able to see what's
happening in one process.
 
Sorry I can't answer your question (hmmph).

P.S. I tried emailing you but my reply got bounced all over Reading and gave
     up...
