"Can Cloud Computing Address the Scientific Computing Requirements
for DOE Researchers? Well, Yes, No and Maybe Can Cloud Computing
Address the Scientific Computing Requirements for DOE Researchers?
Well, Yes, No and Maybe"
January 30, 2012
"After a two-year study of the feasibility of cloud computing
systems for meeting the ever-increasing computational needs of
scientists, Department of Energy researchers have issued
a report stating that the cloud computing model is useful,
but should not replace the centralized supercomputing centers
operated by DOE national laboratories."
"To thoroughly evaluate the cloud computing model, the team ran
scientific applications for studying particle physics, climate,
quantum chemistry, plasma physics and astrophysics on
the Magellan system, as well as on a Cray XT4 supercomputer and
a Dell cluster system. The applications were also run on Amazon's
EC2 commercial cloud offering, including the HPC offering with
Cluster Compute instances, for comparison purposes."
"In the end, the Magellan research teams came up with a set of
*)Scientific applications have special requirements that require
cloud solutions that are tailored to these needs.
*)The scientific applications currently best suited for clouds are
those with minimal communication and I/O (input/output).
*)Clouds can require significant programming and system administration
*)Significant gaps and challenges exist in current open-source
virtualized cloud software stacks for production science use.
*)Clouds expose a different risk model, requiring different security
practices and policies.
*)The MapReduce programming model shows promise in addressing
scientific needs, but current implementations have gaps and challenges.
*)Public clouds can be more expensive than in-house large systems.
Many of the cost benefits from clouds result from the increased
consolidation and higher average utilization.
*)DOE supercomputing centers already achieve energy efficiency levels
comparable to commercial cloud centers.
*)Cloud is a business model and can be applied at DOE supercomputing
"The Magellan Report on Cloud Computing for Science"

".. Magellan was charged with answering the following research questions:"
*)Are the open source cloud software stacks ready for DOE HPC science?
*)Can DOE cyber security requirements be met within a cloud?
*)Are the new cloud programming models useful for scientific computing?
*)Can DOE HPC applications run efficiently in the cloud? What applications
are suitable for clouds?
*)How usable are cloud environments for scientific applications?
*)When is it cost effective to run DOE HPC science in a cloud?
