The DC-API was created by MTA SZTAKI to allow easy implementation and
|
|
deployment of distributed applications on multiple grid environments.

In order to accomodate the needs of very different grid environments, the
|
|
DC-API supports only a restricted master-worker programming model. The
|
|
restrictions include:

Master-worker concept: there is a designated
|
|
<emphasis>master</emphasis> process running somewhere on the grid
|
|
infrastructure. The master process can submit worker processes called
|
|
<emphasis>work units</emphasis>.

Every work unit is a sequential application.

There is support for limited messaging between the master and the
|
|
running work units. It can be used to send status and control
|
|
messages, but it is not suitable for parallel programming.
