  The CEM2k and LAQGSM codes have been recently developed at Los Alamos
National Laboratory to simulate nuclear reactions induced by particles and
nuclei for a number of applications. We have benchmarked our codes against most
available measured data at projectile energies from 10 MeV/A to 800 GeV/A and
have compared our results with predictions of other current models used by the
nuclear community. Here, we present a brief description of our codes and show
illustrative results obtained with CEM2k and LAQGSM for A+p and A+A spallation,
fission, and fragmentation reactions measured recently at GSI compared with
predictions by other models. Further necessary work is outlined.
