Detailed Description

A compute service that manages a set of multi-core compute hosts and provides access to their resources.

One can think of this as a simple service that allows the user to run tasks and to specify for each task on which host it should run and with how many cores. If no host is specified, the service will pick the least loaded host. If no number of cores is specified, the service will use as many cores as possible. The service will make sure that the RAM capacity of a host is not exceeded by possibly delaying task executions until enough RAM is available.
