Provided are methods and systems for providing users with a cluster of virtual machines (VMs) on-demand, whereby a group of VMs are provisioned together. Virtual Cluster as a Service (VClaaS) relaxes many restrictions on virtualizing VMs and provides performance benefits at the same or similar encapsulations and security measures that Infrastructure as a Service (IaaS) typically provides. The VClaaS system enables users to provision an entire cluster of VMs at a time, and also allows for relaxing the isolation barrier between the machines while maintaining the encapsulation barrier for the cluster as a whole, thereby providing users with improved networking, caching, and scheduling experiences.

Virtual cluster as a service (VCIaaS)

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for determining image search results. One of the methods includes scheduling a first computation for execution on each of a first plurality of worker processes. The first computation changes a respective state of each of one or more of the first worker processes from a first state to a second state. A respective second computation is scheduled for execution on each of a second plurality of worker, where each respective second computation will use a different value for a particular variable for two or more of the second plurality of worker processes. The respective state of each of the second plurality of worker processes is updated from the second state to a third state, where the third state corresponds to execution of the second computation using a first value of the particular variable.
