Description

pardiso_64 is an alternative ILP64 (64-bit integer) version of the pardiso routine (see Description section for more details). The interface of pardiso_64 is the same as the interface of pardiso, but it accepts and returns all INTEGER data as INTEGER*8.

Use pardiso_64 when pardisofor solving large matrices (with the number of non-zero elements on the order of 500 million or more). You can use it together with the usual LP64 interfaces for the rest of Intel® oneAPI Math Kernel Library (oneMKL) functionality. In other words, if you use 64-bit integer version (pardiso_64), you do not need to re-link your applications with ILP64 libraries. Take into account that pardiso_64 may perform slower than regular pardiso on the reordering and symbolic factorization phase.

NOTE:

pardiso_64 is supported only in the 64-bit libraries. If pardiso_64 is called from the 32-bit libraries, it returns error =-12.

NOTE:

This routine supports the Progress Routine feature. See Progress Function for details.

Input Parameters

The input parameters of pardiso_64 are the same as the input parameters of pardiso, but pardiso_64 accepts all INTEGER data as INTEGER*8.

Output Parameters

The output parameters of pardiso_64 are the same as the output parameters of pardiso, but pardiso_64 returns all INTEGER data as INTEGER*8.
