With the recent updates to Intel’s VTune™ Amplifier XE 2013, the user interface for the symbol search directories has been streamlined. The new interface should facilitate faster symbol lookups and quicker finalization waits. You can find the new interface in the project properties dialog.
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.
Article <Java support is back in VTune™ Amplifier XE> informs that VTune(TM) Amplifier XE 2013 already supports Java application, and Attaching to Java* processes for hardware event-based sampling is supported since VTune™ Amplifier XE 2013 Update 4.
This is the first article in a series of articles about High Performance Computing with the Intel Xeon Phi. The Intel Xeon Phi is the first commercial product of Intel to incorporate the Many Integrated Core architecture. In this article I will present the basics of the Xeon Phi architecture, the programming models and what we can do to measure the performance in cycles for micro benchmarks.
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:
What's the overhead of having the Intel(R) VTune(TM) Amplifier XE for Linux* modules loaded but un-used and no collection is happening?
If there is no collection in progress, there is no execution time overhead of having the driver loaded. There would also be very little overhead wrt memory.
You can let the module be loaded at boot time (e.g., via the install-boot-script script, which is the default) and not worry about it. Unless data is being collected by VTune Amplifier XE, there will be no latency impact on system perf
