Configuration Notes

Stxxl library

refer to Stxxl homepage
In most cases, few adaptations in stxxl/compiler.make (name of your g++ compiler, path of stxxl) are sufficient

code/tmess/Makefile

The name of the g++ compiler (version 3.2) has to be adapted if it differs from 'g++'
In most cases, no further modifications are necessary
In most cases, the Makefile itself needs no adaptation

code/base/test_all.h

The file 'code/base/test_all.h' contains the test methods for the suffix array construction algorithms (doubling_tst, discard_tst and skew_tst). At the begin of the methods are the constants 'ram_usage' (~ ram consumption per used sorter) and 'block_s' (blocksize of the used sorters). The ram consumption has to be adapted for computers with less than 1GByte ram.

code/skewalg/config.h

Since the DC3/skew algorithm needs external arrays, there is an aditional configuration file. It contains among smaller type definitions the stxxl::vector definitions with parameters. In the most cases there have no changes to be done.

code/tmess/.stxxl

code/sacheck/.stxxl

code/skewalg/.stxxl

The file '.stxxl' contains one line per hard disk. For each disk the first two parameters are the name and the size (in MByte) of the file that is used for the external storage.
