"-collect-with runsa -knob event-config" only works with Basic Performance Tuning Events

For example

event-config=CPU_CLK_UNHALTED.THREAD

works fine. But for many others such as MEM_UNCORE_RETIRED.REMOTE_DRAM

amplxe-cl will give error like:

amplxe: Error: Cannot configure sampling event groups. The collection is terminated.

Could anyone help? Thanks

Windows XE 2015:"Accurate CPU time detection was disabled. Trace session is already in use"

I am using Amplifier XE 2015 on Windows 7 and trying to profile 4xMPI processes running on my local machine. I get 3x of the above messages when running 4 MPI processes. Is that expected? That is it seems that XE is having problems profiling multiple MPI processes at the same time.

mpiexec -n 4 amplxe-cl -result-dir my_result_ah -collect hotspots -- <my_exe.exe>

Cómo usar Intel® HAXM para desarrollar aplicaciones de Android* Wear y Android* TV

Android* ha recorrido un largo camino, que comenzó con los teléfonos y continuó con las tabletas electrónicas, Google TV*, Android Wear*, Android TV* (reemplaza a Google TV) y Android Auto*. Para los desarrolladores, puede ser una tarea difícil crear y probar sus aplicaciones para que funcionen bien en todos estos dispositivos. Si a esto se le agregan los diferentes tamaños de dispositivos y resoluciones de pantalla, el problema de verificar y probar las aplicaciones no tarda en adquirir complejidad. Pero Intel® HAXM viene al rescate.

Estimating FLOPS

I have Intel(R) Core(TM) i7-4800MQ CPU @ 2.70GHz which is Haswell based processor. I want to estimate FLOPS of an application. I am using Intel VTune Amplifier XE 2015. wondering if anybody knows how to find FLOPS?

I tried following steps on https://software.intel.com/en-us/articles/estimating-flops-using-event-b... but I don't find Processor Event Name on the pages in VTune. wondering if anybody has successfully done this on Haswell processor.
