Frequently Asked Questions

  1. Where to use PES? PES is designed for problems where fitness evaluations is the dominating factor in complexity. It perform best on such problems, like problems involving simulation in fitness evaluation.
  2. How many PC's can PES work with? PES currently assumes maximum of 32 Processors. In theory it can work with arbitrary number of processors but it is tested with at most 20 PCs.
  3. Are there any more information avaliable? There is a PES technical report in t-lab page. It gives details about performance of PES.
  4. Where is the documentation of library? It is included in the distribution under 'doc' directory.
  5. Is PES free? Yes. PES is provided as freeware.
  6. PES finishes execution with error -7, why? This error signals that the file in clients can't be found. Check the 'Pesdef.txt'. See appendix[5] for details.
  7. PES works too slow, why? The cause of this problem can be configuration. Check the hosts in the PVM environment. Type 'pvm' to reach console. In this console type conf to see the hosts avaliable. Also PES server component displays avaliable hosts in initialization. If the required hosts aren't avaliable add them to PVM host list as defined in PVM documentation. If still problem persists check 'Pesdef.txt' for the location of executable in clients. See also 1.
