  • Enabling portions of programs to be executed on system z integrated information processor (zIIP) without requiring programs to be entirely restructured
    Patent number: 8938608
    Abstract: A method for allowing portions of programs to be executed on a System z Integrated Information Processor (zIIP). A service call is inserted at the beginning of the zIIP eligible code to enable enclave Service Request Block (SRB)-mode execution on the zIIP processor. An additional service call is inserted at the end of the zIIP eligible code to disable the enclave SRB-mode execution. A module in the operating system, referred to herein as the “zIIP shifter module,” is configured to detect these service calls thereby implementing and terminating the SRB-mode execution so that the zIIP processor executes the zIIP eligible code for the appropriate duration of time. In this manner, only a portion of the programs that contain eligible zIIP executable code is executed on the zIIP processor without requiring the programs to be entirely restructured thereby reducing development cost and improving software development productivity.
