Are there any matrix reordering algorithms available in the MKL API, such as Reverse-Cuthill-McKee or Gibbs-Poole-Stockmeyer? I can't seem to find any references one way or the other.
pstran and pdtran are defined in both mkl_pblas.h and mkl_scalapack.h. Causes build to fail with visual studio, unless commented out from mkl_scalapack.h
I modified DSS solver so that I could solve my own system using it but at the dss_solve_real step memory error occurs. I use malloc to allocate memory for the system while the example dss_sym_c.c uses static constants.
When I try to solve 1000 x 1000 system my program crashes with a segmentation fault. In case of larger systems 100 000 x 100 000 "MKL-DSS-DSS-Error, Out of memory" happens.
Here's the code:
Good afternoon. Interested LU factorization CSR matrix. What function does this for a matrix of type double?
Hi, I need help to calculate Eigenvectors using MKL routines.
I'm taking my first steps at MKL and after installation and linking libraries (I have Ubuntu 12.04, 64-bit) I tried to modify the direct solver dss_sym_c.c so that I could solve my sparse symmetric system which is stored in a binary file (1 based index). I changed CSR system but after that an unclassifiable error uccured at the "reorder step" of the program. What can be the reason of it?
Here's the code:
Добрый день. Есть ли в Intel MKL метод записи значения в разряженную матрицу? И соответственно чтение из нее. Нужно что-то типа такого:
sparseMatrix[1,3] = 0.012;
value = sparseMatrix[1,3];
Если есть, дайте пож-та пример, как такую разряженную матрицу инициализировать и работать с ней.
I want to use DLL and Libs of Intel MKL version 10.3.7.1 in my software program. If I purchase a license copy of latest version of Intel MKL for example 11.0, then do I get access to previous version i.e. 10.3.7.1.
Please let me know if any body knows about this. Thank you in advance.
could you clarify two following questions.
