Forum poll: Intel MKL and threading

Intel MKL users,

We would like to hear from you how you are using Intel MKL with threading. Do you use the parallel or sequential MKL? How do your multithreaded applications use MKL? We would appreciate you to complete a short survey. It takes no more than 5 minutes. Your feedback will help us to make Intel MKL a better product. Thanks!

Troubleshooting HOWTO: Bad hardware? MPSS? Configuration?

Are you having problems with your hardware (Cannot see your Intel(R) Xeon Phi(tm) coprocessor?  Sporadic accessibility?) or with the Intel(R) Manycore Platform Software Stack (Intel(R) MPSS) running reliably?

Attached to this post are PDF "flowcharts" that explain how you can troubleshoot the problem (note:  Both Linux and Windows flowcharts are available), and shows what information you will want to collect if you need to escalate your issue to your OEM provider or Intel.

What collateral/documentation do you want to see?

Do you have questions that you are not finding the answers for in our documentation?  Need more training, source code examples, on what specifically?   Help us understand what's missing so that we can make sure we develop documentation you care about (what is important, and what is nice to have)!   Thank you

FAQS: Compilers, Libraries, Performance, Profiling and Optimization.

In the period prior to the launch of Intel® Xeon Phi™ coprocessor, Intel collected questions from developers who had been involved in pilot testing. This document contains some of the most common questions asked. Additional information and Best-Known-Methods for the Intel Xeon Phi coprocessor can be found here.

Slides from May 4th Webinar on Cilk

Hi all,

We did a webinar this morning at 8am Pacific time on changes and new updates in Cilk in the Intel Parallel Composer beta. I am posting the slides here. Let me know if there's any interest to do another webinar on this around 5pm or so Pacific time - I want to see if there's anyone that couldn't attend due to the time that would have liked to attend. Thanks everyone, and I really enjoyed the questions in today's session.

Error when compiling using Visual Studio 2013 toolset in Visual Studio 2015

Compiling in Visual Studio 2015 with the Visual Studio 2013 platform toolset is not working because of some Intel composer platform files. The Intel configuration is preventing me of compiling legacy applications because of it.

1>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Platforms\Win32\PlatformToolsets\v120\ImportBefore\Intel.Libs.MKL.v120.targets(44,5): error MSB6003: The specified task executable "cmd.exe" could not be run. The working directory "mkl\tools" does not exist.

Compiling the same configuration in Visual Studio 2013 IDE is working. 

MKL 11.2u3 not compatible with FFTW3 (3.3.3)?

Our application uses fftw 3.3.3 (fftw3.h).  It has definitions for export_wisdom_to_filename and export_wisdom_from_filename.   I do not see these definitions in the fftw3.h in the mkl include/fftw header file.   Or anywhere in the distribution.   Using MKL 11.2 Update 3.   Does anyone know how to resolve this?   Optionally, does anyone know if the 11.3 Beta now is compatible with fftw3.3.3 and contains these definitions?
