General Informations

A cluster refers to a group of interconnected computers that work together to perform high-speed computation and data processing tasks. These computers, also known as nodes, are typically connected through a high-speed network and are used to solve complex problems that require a large amount of processing power or storage capacity. Clusters are commonly used in a variety of fields, including scientific research, data analytics, and business intelligence. They are an effective way to harness the power of multiple computers to solve problems that would be too complex or time-consuming for a single machine to handle. The use of Flux parametric distribution is made through a scheduler (PBS, ...)

A cluster scheduler is a software program that coordinates the allocation of computing resources within a cluster. It is responsible for assigning tasks to the different nodes in the cluster and ensuring that the resources needed for those tasks are available. The scheduler also monitors the status of the nodes and the tasks being run, and can make adjustments as necessary to optimize the use of resources.

There are several different types of cluster schedulers, each with its own set of features and capabilities. Some schedulers are designed for use in specific types of clusters. In addition, some schedulers are more suited to handling tasks with long runtimes, while others are better suited for handling a large number of short-duration tasks.

Overall, the goal of a cluster scheduler is to make the most efficient use of the resources available in a cluster and to ensure that tasks are completed as quickly as possible.

The next section provides some informations about PBS scheduler provided by Altair.
