Building on the rich heritage of IBM z System Mainframe technology, PSC delivers solutions for each and every user, whether they are using the IFL specialty engine or not. Our Proxy Coupling Technology was developed to transparently offload CPU processing from z System Mainframe General Purpose Processors (GPP) to lower cost CPU alternatives. Essentially, a processing task may be offloaded from one system to another by means of a proxy task, which has the identical interface as the task to be offloaded, delegating the majority of CPU activity to an offload task on another system.
