The Best of Both Worlds: Bringing Back the Intel® SDK for OpenCL™ Applications

Earlier this year, Intel made the decision to integrate OpenCL™ support into two software development suites: Intel® Integrated Native Developer Experience (Intel® INDE) and Intel® Media Server Studio. At the time, we decided to provide the Intel® SDK for OpenCL™ Applications under a new name: Intel® OpenCL™ Code Builder. OpenCL support at Intel has long-been mainstream, so integrating Intel® OpenCL™ Code Builder into Intel's tool suites for developers made sense.

HPCC - use mkl=cluster and crashing in

I am trying to run the HPCC benchmark on our cluster.

The system has Intel compilers and MKL release 2015.5.223

I am compiling with Openmpi version 1.8.5 also (though I do not think this is the problem)

I am following

I have compiled OK. This seems a bit out of date though.

Set the CNR mode for only one function call

Hi everyone,

I would like to do something like:

... // a lot of stuff with several calls to MKL routines
int cbwrStatus = mkl_cbwr_set(MKL_CBWR_AUTO);
int status = LAPACKE_dsyev( LAPACK_ROW_MAJOR, 'V', 'L', rank, matrix, rank, eigenValues ); 
... // a lot of stuff with several calls to MKL routines

Here, mkl_cbwr_set calls fail with MKL_CBWR_ERR_MODE_CHANGE_FAILURE, obviously.

So, two questions:

- why is it forbidden (impossible ?) to change the CNR mode after a call to some MKL function ?



We have successfully integrated a MIC into a system that we are developing.  We are using SCIF to transfer data from the host to the MIC and from the MIC to the host. However we have a requirement to DMA from the MIC to a block of memory on a FPGA device on the PCI bus. 

Can someone tell me if there is any support that exists for this ? 

Thank you



c# Marshalling LAPACKE_zgesvxx


I implemented a C# program that test LAPACKE_zgesvxx function. 

The example works with x64 platform but fail with x86 platform, return info=-7 error!

I suppose there are difference in function declaration, but I don't know where, and how to solve it.

I did many changes in the declaration part, but with 25 parameters became quite difficult to find the solution.

any ideas?

I Attach the example code and the data files used to test.


Thank you


Problem rotating 32-bit png with alpha channel

I can do this using OpenCV to load the image file and then the WarpAffine function from the ipp_blur_rotate_sample SDK sample; the alpha channel from the original image is preserved however areas in the new rotated image that were not originally present default to 100% opacity which is not what I want. I would like them to default to transparency but cant see how to do this easily without extra processing ( subsequently I am using ippiAlphaComp_8u_AC4R to composite the rotated image with larger video frames and don't want to them obscure parts of the video ).

Hanging on PARDISO Factorization (update MKL 11.1 update4 -> MKL 11.3)


I'm using Sparse Matrix Solver in MKL.

I proceeded with the Version Update in MKL 11.1 update4 with MKL 11.3 this time.

The problem that didn't generate in an existing happens and I inquire.

The phenomenon that I stop in the Factorization process is happening after the update progress.


plz, help.
