A data parallel pipeline may specify multiple parallel data objects that contain multiple elements and multiple parallel operations that operate on the parallel data objects. Based on the data parallel pipeline, a dataflow graph of deferred parallel data objects and deferred parallel operations corresponding to the data parallel pipeline may be generated and one or more graph transformations may be applied to the dataflow graph to generate a revised dataflow graph that includes one or more of the deferred parallel data objects and deferred, combined parallel data operations. The deferred, combined parallel operations may be executed to produce materialized parallel data objects corresponding to the deferred parallel data objects.

Parallel processing of data

An untrusted application is received at a data center including one or more processing modules and providing a native processing environment. The untrusted application includes a data parallel pipeline. Secured processing environments are used to execute the untrusted application.

Parallel processing of data for an untrusted application

Among other disclosed subject matter, a system includes a secure execution domain configured to execute trusted processes. The system also includes a hardware virtualization component in the secure execution domain and configured to implement a virtual machine. The virtual machine is a hardware virtualization of a data processing apparatus and includes a shared virtual memory device and a guest software application coupled to the shared virtual memory device. The system also includes a trusted process in the secure execution domain, separate from the virtual machine and coupled to the shared virtual memory device. The trusted process is configured to communicate with the guest software application through the shared virtual memory device. Communication with the guest software application includes secure communication.
