High level API

The High level API of pylm exposes a series of servers and clients that you can inherit to implement different communication and execution models. A simple example of a standalone server and its communication with the corresponding client can be found in the Introduction.

In each of the flavors, a single server refers to a unique server that connects to a client, while a parallel server refers to the combination of a master server and a series of workers. A parallel server is able to distribute the workload among the available workers, in other words, the master is in charge of the management and the workers do the actual work. You will find a thorough description of each flavor and variant in the following sections.

All servers, regardless of their flavor, have a set of useful tools, documented in Server features. You can also visit the section devoted to Workers if yow want to know the details of those simpler pieces that do the actual work.
