This goal is accomplished in several steps:(1) We briefly describe the elements of our SCC AMI,i.e.,the operating system and HPC scientific applications included in the improved AMI.(From here on,we will generally use the AWS specific terminology:‘‘AMI’’ for a virtual machine image,and ‘‘EC2’’ for the Cloud.) (2) We describe a 2nd generation SCC toolset,consisting of bash scripts,that makes the EC2 cloud perform virtually like a local HPC UNIX cluster,and we verify its improved performance.(3) We present benchmarks for parallel performance of HPC scientific applications,focusing in particular on the intranet performance.(4) Finally,in order to facilitate access to the EC2,we have developed a graphical user interface (GUI) that controls execution and I/O for a prototypical application.
