BNL anticipates significant growth in scientific programs with large
computing and data storage needs in the near future and has recently
re-organized support for scientific computing to meet these needs.
A key component is the enhanced role of the RHIC-ATLAS Computing
Facility (RACF) in support of HTC and HPC at BNL.
This presentation discusses the evolving role of the RACF at BNL, in
light of its growing portfolio of responsibilities and its increasing
integration with cloud (academic and for-profit) computing activities.
We also discuss BNL's plan to build a new computing center to support
the new responsibilities of the RACF and present a summary of the cost
benefit analysis done, including the types of computing activities
that benefit most from a local data center vs. cloud computing. This
analysis is partly based on an updated cost comparison of Amazon EC2
computing services and the RACF, which was originally conducted in 2012.
