QUICK START ============ This is a brief tutorial, that assumes you have installed EPSN and all its dependencies with the install script provided on the EPSN web site. Requirements: full EPSN installation and Bash shell. From the top directory ($TOP) where the 'install-epsn.sh' script has been uncompressed, type the following commands. 1) In a first terminal, launch required services for MPI and CORBA. $ source env-epsn.sh $TOP # set up your environment for EPSN $ omniNames & # start OmniORB Naming Service (*) $ mpd & # start MPICH2 daemon (*) Use -start option the first time you launch omniNames. 2) Then, in a second terminal, launch the Heat2D simulation... $ source env-epsn.sh $TOP $ cd EPSN/src/examples/epsn/heat2d $ ./start_heat2d 3) In a last terminal, launch the EPSN GUI called Simone, connect the Heat2D simulation and enjoy EPSN. $ source env-epsn.sh $TOP $ simone Once you have connected the simulation (by default, the naming service is listening on localhost:2809), then you can play/pause the simulation, get the 'temperature' variable for instance (use permanent get, to get it automatically at each step). It is also possible to visualize the temperature grid online with VTK: select Visualization/VTK Menu; then in the VTK window, add Actor for the 'temperature' variable, and active this variable on screen. 4) Kill services if you don't need them anymore. $ mpdallexit # kill MPICH2 daemon $ pkill -9 omniNames # kill OmniORB Naming Service Nota Bene ---------- Add in your ~/.bashrc the following line to configure your environment: . $HOME/opt/install-epsn/env-epsn.sh $TOP -- A.
