2.1 What version to install

If you are installing the package on a machine that has only one CPU you should install the serial version. For some platforms we have no serial version available. In such cases you can just install the parallel PVM version.

For Windows, there is only serial version available.

If you are installing the package on a machine with more than one CPU, either on the same board or on some distributed machine (for example a Linux cluster of Pentium machines), you should install the parallel version.

The parallel version does not require you to run in parallel: you can use it to run in serial mode as well.
