   3. Either CSP or Condor
   4. Project discussion day, Thursday, February 28

2. Programming-like stuff
   1. Linpack
   2. Grid appliance and Condor
   3. NPB
   4. Read the MPI examples
   5. Do the Dot Product MPI program as follows:

         James will create an input file 
         first entry is size of vector == 1,000,000
         remaining entries are two sets of values, each of length size
      
         Optional:  rewrite the code so that each process reads its portion
         of the vector directly rather than receving it a as a message
      
         Run the dot product code for varying numbers of processes, from
         1 up to 8 and time it.
         Report your times.
      
         Draw a graph:
      
         Graph 1:
         x-axis == number of processes
         y-axis == runtime
      
         Graph 2:
         x-axis == number of processes
         y-axis == speedup
                   speedup = time on 1 process / time on N
      
      
      

   6. Do the Heat Distribution Program from the LSU web site (exercises 6/7). Points will be assigned with the following modifications:
      • (40 points) Write an OpenMP program to perform the 2-D Heat Distribution on 2, 4, and 8 OpenMP threads.
      • (40 points) Write an MPI program to perform the 2-D Heat Distribution on 2, 4, 8, and 16 processes.
      • (10 points) Use Gnuplot to produce the graphical output.
      • (10 points) Write a short report with your graphical output and explain your code, show a table with the running times for each version, and your visualization.
      • Bonus 10 points: Use OpenDX to produce the visualization output.
