Intel is offering FREE online training, in collaboration with Colfax.
The upcoming training will start September 9th and it includes free 3-week remote access to a Intel® Xeon® and Intel® Xeon Phi™ server.
Another series of training will start October 13th.

Could you please provide us with some matrix: what OFED should be used for what OS distribution in case of the latest MPSS (3.5.2, linux)? We need to know in what cases MPSS supports the OFED and in what cases better to use alternative OFED distribution.
I am having a really hard time figuring out how to use the Xeon Phi offload mode from within MATLAB MEX files under Linux. I have managed to force MATLAB to use icc for compilation and verified that the mex files run fine. The problems start when using the offload pragma - as far as I can tell, nobody has tried that yet and I suspect this is some (fixable?) issue with libraries. Can someone here help me with this?
Consider the following simple code
I would like to ask whether using Intel Parallel Studio XE 2016 Beta for Linux it is possible to test OpenMP 4 offloading features in an emulated environment like the one GCC is providing by means of the offloadmic library.
Could you please take a look at this problem? My machine has 16 CPUs and 4 MICs (47 coprocessors each), and I run my program with 8 MPI processors (mpi_comm_size = 8) and want to use MKL routines with automatic offload (AO) mode. As you can see in the test code attached, I tried three different methods.
METHOD-1: I allocate the 4 MICs to the first 4 CPUs each and let the other CPUs run w/o MIC. In this case the program works well as expected and I got the following performance test result when solving zgemm for 5k*5k size of complex & dense matrices.
