Hi, all, I am parallelizing a serial-fortran77 code having .f source files. I am planning to save the fortran source file as .f90 instead of .f files. Then I would use the mpif90 compiler. The fortran77 constructs in the code are understood by mpif90 compiler (i feel so).
Will there be any performance loss (or gain) in compiling the fortran77 code with mpif90 (where the code will be containing some fortran90 constructs as well)? Any opinion? An advantage with mpif90 is that I can use ALLOCATABLE arrays for some basic array variables; saving memory. THANKS A LOT FOR YOUR KIND ATTENTION. With best regards, Amjad Ali.
