In my previous blog, I discussed “Ways to Speeding up Your Cloud Environment…”, I will continue with this thread by introducing the topic of Software Defined Networks (SDN). The industry has been depending on proprietary networking equipment and appliances, essentially creating an environment requiring vertical integrated software running on dedicated hardware.
Download this guide to learn how to identify performance issues on software running on the Intel® Xeon® Processor E5 family
(based on Intel® Microarchitecture Codename Sandy Bridge-EP/EX/EN). The guide explains how to use Intel® VTune™ Amplifier XE's General Exploration profile for Xeon processor E5 servers. It explains how to identify the most common software performance issues and gives suggestions for how to address each.
The lecture given here is the first part in the “Introduction to Parallel Programming” video series. This part endeavors to define parallel computing, explain why parallel computing is becoming mainstream, and explain why explicit parallel programming is necessary. This part sets the tone for the other 11 parts in the series.

Overcome the limitation of optimizing compilers in terms of not knowing which code-execution path is most likely to be used. For example, an optimizer can refine a long series of if statements and have it run at great speed; but if it does not know that in the majority of runs, the very last test is the one that is run, the optimizer cannot rearrange the sequence for best possible performance. It has to work on the assumption that all if tests in the sequence are equally probable.
