Note that the default compiler of System A is set to Cray and the default compiler of System B and C is set to Intel. Therefore, you need to switch from the default compiler to GNU Compiler by executing the module command as below. The default version of GNU Compiler shown in the above list will be set.
When switching from Cray to GNU Compiler (System A):
$ module switch PrgEnv-cray PrgEnv-gnu
When switching from Intel to GNU Compiler (System B, C):
$ module switch PrgEnv-intel PrgEnv-gnuWhen switching between the versions of GNU Compilers, execute the module command with PrgEnv-gnu loaded as below:
$ module switch gcc/4.8.2 gcc/4.6.2To automatically execute a command when logging in to the System, specify such command in the login shell startup-file by following Setting Up System.
For details on the module command, see Modules.

| -fopenmp | Enables compiler recognition of OpenMP directives. |
| -O0/-O1/-O2/-O3 | Specifies general optimization at four levels. (The default is 0.) |
Massage and debugging options
| Option | Purpose |
|---|---|
| -Wall | Displays all warning messages. |
Fortran language options
| Option | Purpose |
|---|---|
| -ffree-form | Specifies that Fortran source programs are written in free source form. |
| -pedantic | Generates messages when nonstandard usage of Fortran is encountered. |
| -fimplicit-none | Warns of the IMPLICIT type statement. |
