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.
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.

Intel® Vtune™: “Error connecting to MIC card”, Why?
Recently, while profiling a workload on the Intel® Xeon Phi™ coprocessor using Intel Vtune, I ran across the following error:
Quote:
ERROR connecting to MIC card, make sure sep_mic_server is running on the card, retrying connection…
ERROR connection to MIC card <1:1046>, errno 111
Using Intel® VTune™ Amplifier XE to Tune Software on the Intel® Xeon® Processor E5 Family
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.
Intel® Xeon Phi™ Coprocessor February Developer Webinar Q&A Responses
Response to our February session of the Intel® Xeon® and Xeon® Phi™ Introduction to High Performance Application Development for Multicore and Manycore-Live webinar was gratifying and overwhelming, but finally we worked through all of your questions. Some of the questions required a context we lost with the transcript and some were only partially formed, or of special interest, or duplicates. We gathered together all the questions of general interest from the webinar and farmed them out to our experts for more complete answers. We'll assembled that list and sorted it by
