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!

Some digits differ from serial to distibuted Cholesky

I am using the double precision routine in C for Cholesky. In order to check the result, I am running the serial version too. For smaller inputs, the results are same, but for a matrix 6500x6500, I am getting some digits differently, should I worry?

Here is the last numbers of the results that differ:


C interface to BLAS


I am running into an inconsistency in the header file mkl.h for BLAS functions being called from C. I finally used the "/E" option from the C compiler to dump the pre-processed source so I could inspect it.

Here are 2 examples of what I find in the header files:

void dgemm(const char *transa, const char *transb, const int *m, const int *n, const int *k,
           const double *alpha, const double *a, const int *lda, const double *b, const int *ldb,
           const double *beta, double *c, const int *ldc);
