2. C* Programming Review Data parallel language
The parallel data structure is the shape
Use the with statement to select the current shape
Use left indexing to access the parallel variable
Use the where statement to mask out values

3. Using C* on our Systems Set up PVM Set up C* Run your program
See the web page for
C* setup instructions
C* primer
C* compiler options

4. Setting up PVM Create the directory $HOME/pvm3
Create the directory $HOME/pvm3/bin/HPPA
Link $HOME/pvm3/lib to ~snell/pvm3/lib
Set the environment variable PVM_ROOT to $HOME/pvm3
Do this in your login script
Set up your .rhosts file
Add $HOME/pvm3/lib/HPPA to your path

5. Setting up PVM
Run pvm
Using the add command, add in appropriate hosts to your virtual machine
Use quit to leave pvm console but leave the virtual machine running
Use halt to kill the virtual machine

6. Setting up C* Add ~snell/cstar/install.PVM.HPPA2D to your path
Set the following environment variables
CSTAR_MODE
scalar, pvm, 2d-pvm
CSTAR_ROWS
Number of rows in virtual mesh
CSTAR_COLS
Number of columns in virtual mesh

7. Running your C* program
Compile your program
cs prog.cs -o prog
Copy the executable to $HOME/pvm3/bin/HPPA
Execute your program
prog args…..
To execute on a single processor either
set up a pvm virtual machine with one processor
set the CSTAR_MODE variable to scalar

8. Assignment Redo lab 1 in C*
Compare your program complexity with your message passing program
Draw graphs to:
Compare your speedups with your message passing program
Compare your execution times with your message passing program
