They are running cpu-intensive calculations on distributed hosts
("high perfomance computing"), so that all hosts share the CPU and RAM
requirements. Tomcat will allow interaction with the MPI application
through the internet.

Any suggestion how I can accomplish the configuration, if I start
tomcat with the MPI web application using "mpirun -n 2 java ..." so
that only the first MPI process opens the tomcat communication ports,
while all other MPI processes disable their communicators?
As an alternative I can run the MPI application as a separate server
(tested across 16 hosts already), and use tomcat as a (serial) client
to this parallel server. The disadvantage is that huge amounts of data
need to be processed another time instead of being served directly
from the MPI application.
Which solution do you suggest?
Thank you
Martijn
