Pardiso generates wrong result for a small test matrix

Hi, 

I've written a test program to get familiar with the pardiso. However I find that comparing with the result from Eigen the pardiso spits out totally incorrect answer. I have totally no idea what went wrong and please help. Code is attached.  The compile command I used is also listed as: 

icpc -I ~/Lib/Eigen -std=c++11 -mkl=parallel -qopenmp -O3 -xCORE-AVX2 PTEST.cpp -o PardisoTest

Best,

Izzy
