Running solvers on multiple cores under 32bit windows or 64bit windows

Windows 7: Installing the MPICH-2 libraries from Argonne National Lab on Windows 7

  1. Type msconfig into "Start" section.
  2. Select Tools Tab.
  3. Select line Change UAC settings.
  4. Press Launch button.
  5. Change Slider from "Default" to "Never notify".

  11. Download the 32 bit windows installer or download the 64 bit windows installer
  12. Run the appropriate installer.
  13. Process Manager Setup Passphrase: for example D27101972K (or keep the default behappy, if it makes you happy)
  14. Select the standard folder: c:\Program Files\MPICH2 because geodict_s.bat in the GeoDict/Applications folder expects this path.
  15. If you end up in c:\Programme\MPICH2 or c:\Program Files (x86)\MPICH2, you must adapt the path in line 30 of geodict_s.bat in your GeoDict application directory.
  16. In the popup Windows Security Alert for the application smpd, select Unblock.
  17. When the solver runs, select Unblock for the application mpiexec if prompted for that.
  18. Revert UAC Settings slider to "Default" (like steps 1.-9.).
  19. Whenever the firewall pop ups -> allow network access.

Windows XP: Installing the MPICH-2 libraries from Argonne National Lab on Windows XP

  1. Log in as administrator
  2. Download the 32 bit windows installer or download the 64 bit windows installer
  3. Run the appropriate installer.
  4. Process Manager Setup Passphrase: for example D27101972K (or keep the default behappy, if it makes you happy)
  5. Select the standard folder: c:\Program Files\MPICH2 because geodict_s.bat in the GeoDict/Applications folder expects this path.
  6. If you end up in c:\Programme\MPICH2 or c:\Program Files (x86)\MPICH2, you must adapt the path in line 30 of geodict_s.bat in your GeoDict application directory.
  7. In the popup Windows Security Alert for the application smpd, select Unblock.
  8. When the solver runs, select Unblock for the application mpiexec if prompted for that.

To avoid a prompt for your password while GeoDict executes a parallel solver when running on more than 1 computer

  1. Replace the -localonly option by -machinefile filename in line 34 of geodict_s.bat in the GeoDict/Applications folder, where filename lists the hosts you wish to use
  2. Open a dos window (start->Run-> type cmd)
  3. Execute the following line
    "c:\Program Files\MPICH2\bin\mpiexec.exe" -np 2 dummy
    Note that "c:\Program Files\Fraunhofer..." should possibly read "c:\Program Files (x86)\Fraunhofer...", depending on the directory you chose to install GeoDict in.
  4. Enter your password
  5. In the popup Windows Security Alert for the application mpiexec, select Unblock.
  6. You may get an error message that dummy could not be found or could not be started - this is due to the fact that dummy does not exist and not a problem.
