We carry out an analysis of the potential of the Large Hadron Collider (LHC) to discover supersymmetry in runs at √(s)=7 TeV with an accumulated luminosity of (0.1--2) fb^\ensuremath-1 of data. The analysis is done with both minimal supergravity and supergravity models with nonuniversal soft breaking. Benchmarks for early discovery with (0.1--2) fb^\ensuremath-1 of data are given. We provide an update of b-tagging efficiencies in PGS 4 appropriate for LHC analyses. A large number of signature channels are analyzed, and it is shown that each of the models exhibited are discoverable at the 5\ensuremathσ level or more above the standard model background in several signature channels which would provide cross checks for a discovery of supersymmetry. It is shown that some of the benchmarks are discoverable with 0.1 fb^\ensuremath-1 of data again with detectable signals in several channels.
