Even though frequency of CPU seems to increase every 18 months but memory bandwidth is becoming the rate limiting component of computers.So, even if we could develop a processor of frequency 6-7 GHZ , it won't be of great use because the CPU would just be spending more time waiting for data to arrive from memory to actually process it.So developing faster CPUs isn't really necessary if we are looking to speed up the performance.Also transistors are becoming very tiny and we are starting to reach the physical limits on just how small we can fabricate chips.
If we want to get more work done at a faster rate we could connect more computers which could share the task.Distributed computing is one way how we could solve the problem.
Distributed system is playing a vital role in the field of animation and graphics.It is used in certain movies to simulate the entire battle field with thousands of virtual warriors.It is also used in rendering multiple frames of high quality animation.
