Оптимизация? Конечно, каждый сталкивался с данной задачей при разработке своих, сколь-нибудь значительных, требующих определённых вычислений, приложений. При этом способов оптимизировать код существует огромное множество, и, как следствие, различных путей сделать это в автоматическом режиме с помощью опций компилятора. Вот здесь и возникает проблема – как выбрать то, что нужно нам и не запутаться?

Intel Xeon Phi Coprocessor April 2013 Developer Webinar Q&A Responses
Answers for the questions raised during the April session of our Introduction to High Performance Application Development for Intel® Xeon® & Intel® Xeon Phi™ processors class have been assembled. There were some duplicates and other questions we couldn't decipher, either because of the wording or because of implied context that was not spelled out. We tried to address the rest, which appear below:
Enabling Connectionless DAPL UD in the Intel® MPI Library
What is DAPL UD?
Traditional InfiniBand* support involves MPI message transfer over the Reliable Connection (RC) protocol. While RC is long-standing and rich in functionality, it does have certain drawbacks: since it requires that each pair of processes setup a one-to-one connection at the start of the execution, memory consumption could (at the worst case) grow linearly as more MPI ranks are added and the number of pair connections grows.
Setting Text Size for Intel® Parallel Studio XE Components on Linux* Operating Systems
Intel® Advisor XE, Intel® VTune™ Amplifier XE, and Intel® Inspector XE all use system GTK* fonts for drawing. They need a vector (scalable) font installed as a default font for the user to show text in different sizes: bigger for titles, smaller for tables and text.
However, you may want to change the font or text size for preference or accessibility reasons. We do not recommend changing the system fonts, obviously, and they are easy enough to override with user-defined fonts stored separately for each user.

Check out the Intel® Advisor XE 2013 Update 3..
Intel® Advisor XE 2013 Update 3 guides developers to add parallelism to their existing C/C++ programs. Using this tool, you can identify where most of the time is spent in your code, which of those locations can actually scale to multi-core and what correctness issues are lurking in those locations. The information provided by this tool can help you decide where to thread your code more judiciously. You can learn more about this tool at the Intel(R) Advisor XE 2013 home page.
