- Libfft Version 2.3 is also included in SGI's Scientific Library "complib",
- which is available with the Fortran 4.0+ compiler.
-
- The current library comes in four formats:
-
- o mips1: compilation flags -O2,
- will run on all systems,
- can be link with C or Fortran compilers.
- This is NOT a parallel version.
-
- o mips2: compiled with the "-O2 -mips2" flags,
- will run only on systems with R4000 CPUs,
- can be used with both C and Fortran compilers.
- This is NOT a parallel version.
-
- o mp_mips1: compiled "-O2 -mp"
- will run all systems.
- Requires Fortran compilers since it uses the Fortran MP library.
- This version will run in parallel on Power Series systems.
-
- o mp_mips2: compiled "-O2 -mips2 -mp"
- will run all Challenge and Onyx systems only.
- Requires Fortran compilers since it uses the Fortran MP library.
- This version will run in parallel.
-
- Note the libraries were compiled under Irix5.1 and the corresponding
- compilers. The object files use the new ELF format, and cannot be mixed
- with routines compiled under Irix4.* which use the classical COFF format.
-
- The TRY directory contains test and timing drivers.
-
- The fft1 and fft2 directories contain examples using fftlib. To run
- them, modify the Makefile to point to the appropriate fftlib for your
- machine and type make. To run the example, simply type RUNME.
-
- Finally in the DOC directory you will find a ASCII documentation file.
