BACON outlier detection

I'm trying to run the following code:

#include <iostream>

#include "mkl.h"

int main () {

    /* Define vector of obseravations (5 2D observation points) */

    float pObservations [] = {1., 2., 3., 4.2, 5, 9., 10., 8., 7., 6., 5., 9.};

    /* Creates and initializes a new summary statistics task descriptor */

Poisson solver on a sphere


I'm trying to use Poisson Solver Routines to solver Poisson equation on a whole sphere. After reading the manual, I compile and execute the example code 'd_sph_with_poles_f.f90' with command 'make libintel64 function=d_sph_with_poles_f threading=sequential'. The solution of Helmholtz problem seems to be OK, but when I set q = 0.0D0 to solve the Poisson problem, I got the following error message:

"The problem is degenerate due to rounding errors. The approximate solution that provides the minimal Euclidean norm of the solution will be computed"

scalapack libraries not available

Hi there,

I have downloaded and installed parallel_studio_xe_2016_update3. Then I have migrated a MPI project to the new machine. When I am trying to link with mkl_blas95_lp64.lib mkl_lapack95_lp64.lib mkl_scalapack_lp64.lib mkl_intel_lp64.lib mkl_core.lib mkl_sequential.lib mkl_blacs_msmpi_lp64.lib impi.lib 

as the link line adviser recommends - it is missing:

How Intel® Xeon Phi™ Processors Benefit Machine Learning/Deep Learning Apps and Frameworks

Machine learning can take very large amounts of data to predict possible outcomes with a high degree of accuracy. The second-generation Intel® Xeon Phi processor has the processor performance and memory bandwidth to address complex machine learning applications.

License with Mathematica

Hi everybody,

I do have a licence question.

We are using functions from a Mathematica script inside our application. These generated DLLs from Mathematica(Wolfram) are using the MKL-dlls from Intel.

If we want to distribute this application, do we need to purchase an Intel-license by ourselves? Or is this already included in the license which is used by Wolfram/Mathematica?

Any help is appreciated!,

Kind regards,


Linpack runs only on cores, not threads?

hi there,

I use the linpack binaries quite a long time for various stuff, most times for performance and stability diagnostics.

I recognized the with current versions of the binaries and current CPUs linpack does only run on the cores and not on th HT threads anymore (quite sure that this was different earlier); e.g. with a E5-2683 v4 (16 cores 32 threads) I see only 16 used CPUs in the O/S...

Any idea why this changed? Reason is CPU or binary?


Thank you for your help





dfeast_scsrev problem

Hi Everybody
I have a problem regarding eigenvalue calculations for my system with dfeast_scsrev
as you know this function supposed to solve standard eigenvalue problem for sparse matrices.
My code was working fine previously but since I changed to bigger system(65536x65536) I have a segmentation fault. when I run my code with gdb I will see that the memory issue is regarding function mkl_feast_dfeast_srci () which I do not call it in my program.

Writing c extension for python that calls mkl and can use more than 1 cpu.

I tried directly calling the mkl from python with ctypes, but in that case, mkl can only use a single cpu. The cause of that problem is unknown.

I am writing a c extension for python that calls the mkl as an alternative approach.

The following c extension can be imported into python without problem. However, when I call the function, it created the following error message:

    Intel MKL FATAL ERROR: Cannot load or

Gaussian Random Numbers

Dear Intel:

I have been using the BM Gaussian Random Number routines.  These were developed in about '58 for the Army by Muller and Box at Princeton. Your routines reference one of their minor notes as providing the basis for your routines. The real math is contained in Technical Report 9 and 13 from the Princeton -- Number 9 is scanned but is quite hard to get a hold off - one has to ask for it as a PDF and the quality is not good and 13 - we have asked for it to be scanned and hopefully it will become available.

Dummy Libraries Suddenly are Desired


Earlier today, I went and recompiled some code after something was accidentally deleted. Much to my surprise, the following errors occured:

icpc: error #10236 File not found:   '/opt/intel/composer_xe_2015.2.164/mkl/lib/em64t/libmkl_lapack.a'

icpc: error #10236 File not found:   '/opt/intel/composer_xe_2015.2.164/mkl/lib/em64t/libmkl_em64t.a'

icpc: error #10236 File not found:   '/opt/intel/composer_xe_2015.2.164/mkl/lib/em64t/libguide.a'
