Although Cloud computing emerged for business applications in industry,
public Cloud services have been widely accepted and encouraged for scientific
computing in academia. The recently available Google Compute Engine (GCE) is
claimed to support high-performance and computationally intensive tasks, while
little evaluation studies can be found to reveal GCE's scientific capabilities.
Considering that fundamental performance benchmarking is the strategy of
early-stage evaluation of new Cloud services, we followed the Cloud Evaluation
Experiment Methodology (CEEM) to benchmark GCE and also compare it with Amazon
EC2, to help understand the elementary capability of GCE for dealing with
scientific problems. The experimental results and analyses show both potential
advantages of, and possible threats to applying GCE to scientific computing.
For example, compared to Amazon's EC2 service, GCE may better suit applications
that require frequent disk operations, while it may not be ready yet for single
VM-based parallel computing. Following the same evaluation methodology,
different evaluators can replicate and/or supplement this fundamental
evaluation of GCE. Based on the fundamental evaluation results, suitable GCE
environments can be further established for case studies of solving real
science problems.Comment: Proceedings of the 5th International Conference on Cloud Computing
