pdsma − CUTEr PDS test driver

pdsma

The pdsma main program test drives PDS on SIF problems from the CUTEr distribution.

PDS is a nonlinear programming code for unconstrained problems, which only uses function values (no derivatives needed). It is especially intended to be used in a parallel computing environment.

PDS was written by V. Torczon (email: va@cs.wm.edu). The following notice goes with the PDS distribution:

The object module pdsma.o is stored in $MYCUTER/precision/bin, where precision is either "single" or "double", according to your local installation.

Compile (but do not link) the PDS source code and copy the resulting object file pds.o in the directory $MYCUTER/precision/bin. Launch using pds(1) or sdpds(1).

If no PDS.SPC file is present in the current directory, the default version is copied from $CUTER/common/src/pkg/pds/. The default specifications are as follows

500

MAXITR

maximum number of iterations allowed

2

TYPE

0 given 1 right 2 regular 3 scaled rt

(1,2 & 3 constructed)

1.0

SCALE

if type not 0 scale contains base

length (and orientation)

4

DEBUG

flag 0 (none) 1 2 3 and 4 give

progressively more info.

256

SSS

number of points used in the search.

PDS is not available in single precision.

CUTER

Parent directory for CUTEr

MYCUTER

Home directory of the installed CUTEr distribution.
