Programming example
program variableTesting
implicit none
! declaring variables
integer :: total,average
complex :: cx
logical :: done
character(len=80) :: message ! a string of 80 characters
!assigning values
total = 20000
average = 1666
done = .true.
message = "A big Hello from HPC"
cx = (3.0, 5.0) ! cx = 3.0 + 5.0i
if (total .ge. average) then
print *, total, " greater or equal than average"
else
print *, total, " less than average"
endif
Print *, average
Print *, cx
Print *, done
Print *, message
end program variableTesting
Modules Available
The following modules are available:
- module load gcc/4.9.3 (GNU compiler)
- module load intel/compiler/64/2016.2.181 (Intel compiler)
Compilation
The program would be compiled in the following way, optional Intel compiler available too:
[username@login01 ~]$ module load gcc/4.9.3 [username@login01 ~]$ gfortran -o testFortran testFortran.f03
