Problems with DSS routine

I am beginner of MKL. I just want to use the DSS routine to solve a large sparse matrix equation. I revised the DSS example according to the manual. But it could not work with the error message "forrtl: severe (157): Program Exception -access violation".

I wonder if DSS routine has a size limitation for the solving sparse matrix.

Could someone tell me how to fix this problem? Please find my code attached.

Your help would be fully appreciated.

HI,

I've put your data into PARDISO interface and obtain following error:

*** Error in PARDISO (incorrect input matrix ) error_num= 24

*** Input check: j=1410, ja(j)=72, ja(j+1)=67 are incompatible

The reason of this failure: in 72th row elements store in incorrect format - column of 1411th element is less than column of element with 1410 number in spite of they lie in one row!

Thanks,

Alex

Hi Alex,

Thank you for the kind help.

I just wonder if you could tell me how to use PARDISO to do the input data check. I could find no such information on the manual.

Best regards,

Tianyu
