HPC Cloud Architecture to Reduce HPC Workflow Complexity in Containerized Environments

Energy-Efficient Scheduling of HPC Applications in Cloud Computing Environments

The use of High Performance Computing (HPC) in commercial and consumer IT applications is becoming popular. They need the ability to gain rapid and scalable access to high-end computing capabilities. Cloud computing promises to deliver such a computing infrastructure using data centers so that HPC users can access applications and data from a Cloud anywhere in the world on demand and pay based ...

Migration Techniques in HPC Environments

Hpc Cloud Applied to Lattice Optimization∗

As Cloud services gain in popularity for enterprise use, vendors are now turning their focus towards providing cloud services suitable for scientific computing. Recently, Amazon Elastic Compute Cloud (EC2) introduced the new Cluster Compute Instances (CCI), a new instance type specifically designed for High Performance Computing (HPC) applications. At Berkeley Lab, the physicists at the Advance...

Pluggable Architecture for Java HPC Messaging

Efforts to build Java messaging systems based on the MPI standard have typically followed either the JNI approach or the pure Java approach. On commodity platforms like Fast Ethernet, advances in JVM (Java Virtual Machine) technology now enable networking applications written in Java to rival their C counterparts. On the other hand, improvements in specialized networking hardware have continued...

Architecture Characterization of DoD MSRC HPC Platforms

This paper outlines the results for a set of low-level, architecture characterization benchmarks that measure the performance of dense numerical computations, access to the memory hierarchy and MPI message passing of three high performance architectures. The machines evaluated are the Cray T3E, IBM SP, and SGI Origin 2000 platforms at the CEWES Major Shared Resource Center. Verification of the ...
