It's a formatting issue. Since your file's suffix is ".f", fixed form is used. Hence, the directives need to start in column 1. Matt used a ".f90" suffix where free format was used.

You have three options, compile with "-Mfree", move the "!$OMP" directives to the first column, or rename your file to "main.f90".

Hope this helps,
Mat

Code:
% pgf90 -mp main.f -Minfo
% a.out
 Thread             0  local sum:     500500.0000000000     
 Global Sum:     500500.0000000000     
FORTRAN STOP

% pgf90 -mp main.f -Minfo -Mfree
main:
      9, Parallel region activated
     12, Parallel loop activated with static block schedule
     15, Barrier
     17, Begin critical section (__cs_unspc)
     18, End critical section (__cs_unspc)
         Parallel region terminated
% a.out
 Thread             0  local sum:     7875.000000000000     
 Thread             7  local sum:     117250.0000000000     
 Thread             6  local sum:     101625.0000000000     
 Thread             4  local sum:     70375.00000000000     
 Thread             2  local sum:     39125.00000000000     
 Thread             3  local sum:     54750.00000000000     
 Thread             5  local sum:     86000.00000000000     
 Thread             1  local sum:     23500.00000000000     
 Global Sum:     500500.0000000000

I had a reply just like mat's but mat beat me to it.

And I learned that PGI supports ! as a comment character in column 1! (My edit used c$OMP).

Whooops! You're absolutely right! I didn't notice!

Thanks! Addressing the formatting issue worked perfectly!
