In this paper we classify the ten dimensional half BPS solutions of the type IIB supergravity which have SO(4)×SO(4)×U(1) isometry found by Lin-Lunin-Maldacena (LLM). Our classification is based on their asymptotic behavior and causal structure according which they fall into two classes: 1) those with R×S3 boundary and 2) those with one dimensional light-like boundary. Each class can be divided into some subclasses depending on asymptotic characteristics of the solutions. We analyze each of these classes in some detail and elaborate on their dual gauge theory description, the corresponding 2d fermion picture and matrix Chern-Simons theory as the effective theory of the half BPS spherical threebrane probes.
