  We study the evolution of two fiducial configurations for binary neutron
stars using two different general relativistic hydrodynamics(GRHD), distributed
adaptive mesh codes. One code, HAD, has for many years been used to study
mergers of compact object binaries, while a new code, MHDuet, has been recently
developed with the experience gained with the older one as well as several
novel features for scalability improvements. As such, we examine the
performance of each, placing particular focus on future requirements for the
extraction of gravitational wave signatures of non-vacuum binaries.
