Sparse matrix - vector product

I use the MKL_ZCSRSYMV routine in a FORTRAN code. The sparse matrix (a) is very large and then I need that indexing vectors (ia and ja) where INTEGER*8 instead of INTEGER.

How can I do?

This should be covered by our "ILP64" interface. When you link to Intel MKL you have the choice on 64-bit systems to use the "LP64" or "ILP64" interfaces and the difference revolves around whether you use 32-bit (INTEGER) or 64-bit integers (INTEGER*8).  Use our link line advisor for finding the right libraries to link.
