A computer cluster is a group of loosely coupled computers that closely work
together so that, in many respects, they can be thought of as a single
computer. The components of a cluster are commonly connected to each other
through fast local-area networks. Clusters are most often used to provide
greater performance and availability than that provided by a single
computer and are typically more cost-effective than single computers of
comparable speed and availability.
A cluster of multiple computers is different from a single computer with
multiple processors or cores.
StataCorp sells Stata/MP, which is a version of Stata providing extensive
support for parallel computations on multiple-processor and multiple-core
computers. StataCorp does not sell a version of Stata that supports
parallel computations across multiple computers (cluster-processing
capabilities).
Some sites have written custom scripts for running computationally intensive
tasks, such as simulations, that allow running multiple copies of Stata
simultaneously in a clustered environment. Typically, one master Stata task
runs on one of the computers in the cluster, hands out batch jobs to other
instances of Stata running on the other computers in the cluster, and
collects the results.
To run Stata in a clustered environment, a separate Stata license is
required for each computer in the cluster. If each of the computers is a
multiprocessor computer, Stata/MP may be used to perform parallel
computations on each computer. You can read more about Stata/MP
here.
If more than one person will be using Stata simultaneously on a cluster, a
network license for the number of simultaneous users is required.
