BiM (release
2.0, April 2005)
The Fortran 77 code BiM is made up
of the
following three files:
- bim.f
containing the core integrator,
- subbim.f
containing auxiliary subroutines and functions,
- param.dat
containing various parameters.
A compressed file
containing all of the above files is also available.
In the following, we report some numerical results, on a suitable set
of stiff test problems taken from the Geneva Test Set and from the Test Set for
IVP Solvers, comparing the code BiM
with some of the best currently available codes: DASSL,
GAM, MEBDFDAE,
RADAU, and RADAU5.
All the numerical tests have been performed on an AMD Athlon64
3200+ personal computer (with 1 GByte of central memory) under Linux,
by using the Gnu Fortran 77 compiler (g77), Vs. 3.3.5, with the -O3
optimization parameter.
Test problems:
Some Notes.
Any comment concerning the code is welcome:
please report them to either Luigi
Brugnano or Cecilia
Magherini.
