ADCIRC contains options that can be specified at compile time using compiler flags as follows:

REAL4 - specifies that most real variables will be handled as REAL*4 (although coordinate related variables, elemental areas and elemental coefficients are always declared as REAL*8). The default is that all real variables are handled as REAL*8. This flag affects code precision and execution time.
CMPI - specifies that MPI library calls will be included in the code for parallelization. The default is no MPI calls.
CVEC - specifies that the code will be optimized for a vector computer. The default is off.
CSCA - specifies that the code will be optimized for a scalar computer. The default is off.
CMACHSUN - specifies that underflow statements that appear to be required to run on a SUN computers will be included in the code. The default is to not include these statements.
