Abstract

A coexecutor for executing functions offloaded from central processors (CPs) in a data processing system, as requested by one or more executing controlprograms, which include a host operating system (host OS), and subsystem programs and applications executing under the host OS. The offloaded functions are embodied in code modules. Code modules execute in the coexecutor in parallel with non-offloaded functions being executed by the CPs. Thus, the CPs do not need to execute functions which can be executed by the coexecutor. CP requests to the coexecutor specify the code modules which are accessed by the coexecutor from host shared storage under the same constraints and access limitations as the control programs. The coexecutor may emulate host dynamic address translation, and may use a provided host storage key in accessing host storage. The restricted access operating state for the coexecutor maintains data integrity.
Coexecutors can be of the same architecture or of a totally differentarchitecture from the CPs to provide an efficient processing environment for theoffloaded functions. The coexecutor interfaces host software which provides therequests to the coexecutor. Offloaded modules, once accessed by the coexecutor,may be cached in coexecutor local storage for use by future requests to allow subsequent invocations to proceed without waiting to again load the same module.
