Installing PTP Software. Click Help - Install New Software, select Available Software Sites, and in the text filter type PTP. Select the first site from the list. Back in the software install dialogue, type in the text filter PTP, select the first site, mark the three software packages from the list, then click Next.

3 Building the Scalable Debug Manager Installing PTP Software. In a terminal window, locate the plugins directory under Eclipse. In that directory, locate a platform specific directory similiar to one of these: org.eclipse.ptp.linux.x org.eclipse.ptp.linux.x org.eclipse.ptp.macosx.ppc org.eclipse.ptp.macosx.x org.eclipse.ptp.aix.ppc Change to that directory, then type sh./build.

4 MPICH2 MPICH2 is a standard for the Message Passing Interface (MPI) which can be used in the development of Cactus applications. Message Passing Daemon. Install the mpich2 and mpich2-devel packages. Ensure $PATH includes the new mpich2 bin/ folder. Re-build Cactus for parallel architecture. Run mpd in a terminal to start the message passing daemon.
