Hello,

I ran the ‘in.intel.rhodo’ test in USER-INTEL/TEST directory with and without offloading to the Intel MICs. The test runs just fine without offloading, but, when offloading, we get the following error:

We built the LAMMPS 5Nov2016 version with the Intel 16.1.150 compiler and MKL and IntelMPI 5.1.2.150. We followed the /MAKE/OPTIONS/Makefile.intel_coprocessor make file. Is there something we are missing in the compilation or a potential bug? Please let us know if more information is required.

Thank you,
