An Overview of Intel's MMX Technology

An introduction to MMX and how to take advantage of its capabilities in your program.
Conclusion

Is all this worth the trouble? The answer to this question depends on the importance you give to speed. Comparing the MMX example program to a pure C language version, the speed improvements speak for themselves. The MMX routine is roughly 14 times faster than the C version (Listing 2 in the archive file) when compiled with no optimizations and about five times faster when full -O2 optimizations are enabled. Of course, you will lose portability and will probably have a harder time writing and debugging assembly language code. Life's full of tough choices, isn't it?

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
