A few words on using OpenMP on the Sun E10000

• ImportantYou should submit your OpenMP jobs using a script (as described on the 7th page of the handout) rather than the interactive method described on page 5.
• I'm told you can compile C programs using the compiler /usr/local/apps/KAP/guide39/bin/guidec
• Here is a manual for OpenMP for Fortran.
• The directory /usr/local/apps/KAP/guide40/OpenMP_examples on Gaos has a bunch of examples of OpenMP usage. Note that examples are for subroutines - to try out an example, you'll need a main program, which in Fortran looks something like:
  > program test
  > integer i,j,n
  > real a(50,50), b(50,50)
  > C Your program should use "double precision" in place of "real"
  > n=50
  > do i = 1, n
  > do j = 1, n
  > a(i,j) = i+j
  > enddo
  > enddo
  >
  > call do_1(a,b,n)
  > end
  > C Now comes the code from the example
  > subroutine do_1(a,b,n)
  > etc etc
