In this article we will review the computational challenges in the beam-beam simulation for the polarized proton run of the Relativistic Heavy Ion Collider (RHIC). The difficulties in our multi-particle and million turn tracking to simulate the proton beam lifetime and proton beam emittance growth due to head-on beam-beam interaction and head-on beam-beam compensation are presented and discussed. Soultions to obtain meaning physics results from these trackings are proposed and tested. In the end we will report the progress in the benchmarking of the RHIC operational proton beam lifetime.
