I have the following installed on my computer:
Intel Parallel Studio XE 2016 Update 2
Intel Parallel Studio XE 2016 Update 3
I think I have come across a serious bug in the latest MKL Pardiso 11.3 update 3.
Attached is a simple program that reads in a test matrix and right-hand-side. I have included all the test input files in the attached zip file.
The MKL Pardiso is called to solve the system.
When compiled with Update 2, the program runs fine. However, when compiled with Update 3, the system is NOT solved and the right-hand side is returned in the solution vector.
