20140019793 | STRICTLY INCREASING VIRTUAL CLOCK FOR HIGH-PRECISION TIMING OF PROGRAMS IN MULTIPROCESSING SYSTEMS - The present invention relates to a method of building virtual clocks that guarantee strictly increasing and high precision timekeeping of programs executed on multiprocessor systems. Specifically, a multiprocessor system is defined as a computing system composed of multiple processing units, where a processing unit is formed of multiple processor cores which operate asynchronously with each other. In addition each processor core has a time counter and operates with one of multiple operating frequencies and can change the operating frequency dynamically. The method builds a high-precision Strictly Increasing Virtual Clock (SIVC) on top of a computer system's time counter which is used as the reference time counter to which a control layer is implemented for capturing the system events that can advance or delay the elapsed time count of system clocks. In this way, SIVC can provide to the computer system a time counter which produces strictly increasing and high-precision values. A program will access SIVC information by using either an operating system call or a hardware instruction. A computer program will create a SIVC on top of a selected computer system's time counter and by isolating it from differences in time count caused by internal changes of the computer system such as internal replacements of a time counter by the system. The present invention guarantees that the SIVC values are strictly increasing and highly precise. | 01-16-2014 |
