Performance Improvement of Multi-Core Architecture Using Whetstone Application in Linux


P. Bala Subramanyam Raju, P.Govindarajulu


Vol. 13  No. 10  pp. 47-53


The most important characteristic of computers is the speed of the central processing unit. Application [1] Performance on modern processors has become increasingly dictated by the use of on-chip structures speed and software’s like Operating system services, Compilers etc. The need of more performance was increasing day by day. The [21] computer system needs to satisfy an end-user application in terms of performance. It is useful as an initial filter to compare systems using 'standard' benchmark programs. This paper uses whetstone synthetic benchmark application to measure the speed and performance at which a computer performs floating point operations on multicore processor and improves the multi-core processor performance by modifying the existing algorithm to run on multicores by dividing the program as parent and child process to obtain the maximum performance on Linux operating systems.


Chip Multiprocessors (CMPs), MWIPS stands for Million Whetstones Instructions per Second. MIPS, Million Instructions per Second, MOPS Millions of Operations per Second.
