    • Making visualized call graph from Intel® VTune™ Amplifier XE results

    Some developers like performance data representation in form of “call graph”, where nodes are functions and edges are function calls from caller to callee. Also functions are attributed with CPU time. This way of call sequence visualization is not necessary needed and VTune™ Amplifier XE doesn’t have this graph – there are a lot of other powerful interactive ways to view, sort and filter performance data.

    But there are good news for those who likes call graphs: it’s possible to make them from VTune Amplifier XE results. This blog post describes the way how to do it.

    Compiler Methodology for Intel® MIC Architecture

    Overview


    Are you initializing data or copying blocks of data from one variable to another in your application?  Probably so.  Moving or setting blocks of data is very common.  So how to best optimization these operations for Intel(R) Xeon Phi(TM) Coprocessors?

    • Setting Text Size for Intel® Parallel Studio XE Components on Microsoft Windows* Operating Systems

    Intel® Inspector XE, Intel® VTune™ Amplifier XE, and Intel® Advisor XE use Microsoft Windows* OS system fonts to select text size. This allows the components to automatically pick up any change you make for accessibility or personal preference without affecting any other component user on the system.

     Therefore, changing the text size for the Intel® Parallel Studio XE GUI is simple. Just change the Windows* text size and reopen the component.
