<p class="MsoNormal">Hi, all,</p>
<p class="MsoNormal">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).</p>
<p class="MsoNormal">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?</p>
<p class="MsoNormal">An advantage with mpif90 is that I can use ALLOCATABLE
arrays for some basic array variables; saving memory.</p>
<p class="MsoNormal">THANKS A LOT FOR YOUR KIND ATTENTION.<br>With best regards,</p>
