CSS 434 Lab Work 2: MPI Java Professor: Munehiro Fukuda Lab work date: See the syllabus 1. Purpose This laboratory work intends to mitigate your steep learning curve on MPI Java. After the professor explains how to use MPI Java and demonstrates an execution of ~css434/hw3/MatrixMult.java, you are to code and run an MPI Java program that includes MPI.COMM_WORLD.Send( ) and MPI.COMM_WORLD.Recv( ) 2. Statement of Work 1. Set up your execution enviornment as instructed below by the UWB IS Linux administrator: MPICH is now installed on all the Linux Lab computers. The process for setting it up to run the first time for each user is cumbersome. After the initial user set-up it works well without much fuss. # login as self # make file .mpd.conf vi/emacs/pico .mpd.conf # in it write one line: secretword= where is a secure key you create but not your normal password save the file # set the correct permissions on this file (other permissions won't work) chmod 600 .mpd.conf # copy the mpd.hosts file to your home directory cp /usr/apps/mpich2/mpd.hosts ~/mpd.hosts edit .bash_profile file - add mpich path to $PATH PATH=$PATH:/usr/local/mpich2/bin

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
