Binary neutron stars are prime targets for gravitational

wave searches by LIGO. The gravitational wave signal at merger encodes

information about the nuclear equation of sate of neutron star matter

in parameter regions inaccessible by terrestrial experiments. Neutron

star mergers are also leading candidates to provide the central engine

in short gamma ray bursts. Thus the problem attracted significant

interest in the past from both numerical researchers and theoretical

physicists. I report on recent progress in simulating binary neutron star mergers

and numerical techniques appropriate to simulate long inspirals

efficiently and accurately.
