NI Real-Time Hypervisor programming utilizes development of virtualization for running LabVIEW Real-Time close by to Windows XP, Red Hat Enterprise Linux or Windows 7 on stand out controller. In present days the multi criteria choice making systems are playing an important role for determination of best among the available choices. Multiple Criteria decision Making (MCDM) systems are focused around accumulating importance to the concept of -closeness to perfect". In this paper four

... a decision making(MCDM) techniques Simple Additive Weighting (SAW) Method, Weighted Product Method (WPM), Grey Resolution Analysis (GRA), and TOPSIS algorithms are analyzed for Windows or Linux as general purpose operating systems. LabVIEW Real time system and the general purpose operating systems access the shared memory and for synchronizing it they use either blocking or polling methods. The test results of the system are considered and their efficiency and performance is calculated using the above four algorithms.
