MM5 Model on SUN
Compiling MM5 on SUN
If you use default compiler options on a SUN from configure.user
and MM5 stops with the following message:
STOP: IN SUB. EXMOISS, NSTEP TOO LARGE, PROBABLY NAN
you may have a bugged Sun compiler (version 4.2). To get around
this problem, you can do one of the following:
-
compile everything with the default options. Then recompile
subroutines addrx1c.F and addrx1n.F in memory/address replacing
-fast
with
-fast -xtarget=generic
(Fix provided by Dr. Harry Edmon of U. of Washington.)
-
reduce optimization level from -O2 to -O1. This can result
an increase in CPU time required to make a model run.
MM5 Pre-processing Programs on SUN
The new Fortran 90 programs, REGRID, INTERPF, and NESTDOWN require
Sun's Fortran 90 compiler version 2.0 or higher. These program do
not compile with versions lower than 2.0.
