|
|
ADD_BLAS_TWO_UNDERSCORES
|
|
ADD_BLAS_ONE_UNDERSCORE
|
|
may be needed depending on how blas/lapack are
|

|
|
|
Output Definitions:
|
|
|
|
FLUSH : define FLUSH if you want output to be written
|
|
immediately to disk and not keep in buffers
|
|
(useful in case of crash)
|
|
DIRECT_IO_FACTOR : record length in direct-access I/O is given by
|
|
the number of real*8 words times DIRECT_IO_FACTOR
|
|
C_POINTER : the type for C pointer
|
|
integer*8 for 64-bit machines,
|
|
integer on most other machines
|
|
DIMAG : intrinsic functions for imaginary part of a
|
|
complex number in double precision
|
|
dimag for 32-bit machines, aimag otherwise
|
|
DREAL : intrinsic functions for real part of a
|
|
complex number in double precision
|
|
dreal for 32-bit machines, real otherwise
|
|
DCMPLX : intrinsic functions for (real,real) to complex
|
|
conversion in double precision
|
|
dcmplx for 32-bit machines, cmplx otherwise
|
|
Blas/Lapack names: single-precision names for 64-bit machines,
|
|
double-precision names for 32-bit machines,
|
|
with underscores appended if requested
