Pardiso thread, vs. core, usage

I'm wondering if it's possible to run Pardiso on more than one thread per core on linux, or if certain behind-the-scenes optimisations have been set. That is, with the following env:

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}
span.s1 {font-variant-ligatures: no-common-ligatures}

$ env | grep PARDISO

MKL_DOMAIN_NUM_THREADS=MKL_DOMAIN_PARDISO=56

And with the following hardware configuration, per (excerpted) /proc/cpuinfo:

processor   : 55

vendor_id   : GenuineIntel

cpu family  : 6

model       : 63

model name  : Intel(R) Xeon(R) CPU E5-2695 v3 @ 2.30GHz

Our 2x14 core machine still only produces the following (excerpted) Pardiso call summary:

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; -webkit-text-stroke: #000000}
p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; -webkit-text-stroke: #000000; min-height: 14.0px}
span.s1 {font-kerning: none}

Statistics:

===========

Parallel Direct Factorization is running on 28 OpenMP

< Linear system Ax = b >

            number of equations:           89317

            number of non-zeros in A:      57771613

            number of non-zeros in A (%): 0.724180

BTW, our OS is CentOS release 6.6, with 64 bit icc, composer_xe_2015.3.187

Any info much appreciated,
