Interactive Parallelization Tool (IPT) is a semi-automatic tool that can be used by domain experts and students for transforming certain classes of existing applications into multiple parallel variants. An end-user of IPT provides existing application ...

Computational Discovery Desktop (CDD) is an application-independent middleware that aids researchers in the daily interaction with distributed HPC resources. It provides computational project management at personal, research group, and inter-...

The use of simulation based engineering taking advantage of massively parallel computing methods by industry is limited due to the costs associated with developing and using high performance computing software and systems. To address industries ability ...

The next generation of supercomputers presents new and complex challenges that might require a change in the current paradigm of how parallel applications are developed. Hybrid programming is usually described as the best approach for exascale ...

Here we describe the CIPRES Workbench (CW), an open source software framework for creating new science gateways with minimal overhead. The CW is a web application that can be deployed on a modest server, and can be configured to submit command line ...

OpenACC provides a high-productivity API for programming GPUs and similar accelerator devices. One of the last steps in tuning OpenACC programs is selecting values for the num_gangs and vector_length clauses, which control how a parallel workload is ...

Since its birth in 2006, Twitter has evolved to a multi-purpose social media that attracts hundreds of millions of users to share their activities and ideas on a daily basis. The potential of capturing fine-grained activity log of users, combined with ...

This paper describes an effort at the University of Tennessee's National Institute for Computational Sciences (NICS) to integrate Apache Spark into the widely used TORQUE HPC batch environment. The similarities and differences between the execution of a ...

Scientists and engineers using supercomputer clusters should be able to focus on their scientific and technical work instead of worrying about operating their user environment. However, creating a convenient and effective user environment on modern ...

The increasing expansion of computations in non-traditional domain sciences has resulted in an increasing demand for research cyberinfrastructure that is suitable for small- and mid-scale job sizes. The computational aspects of these emerging ...

In this paper, we describe Bridges, a new HPC resource that will integrate advanced memory technologies with a uniquely flexible, user-focused, data-centric environment to empower new research communities, bring desktop convenience to HPC, connect to ...

Jetstream will be the first production cloud resource supporting general science and engineering research within the XD ecosystem. In this report we describe the motivation for proposing Jetstream, the configuration of the Jetstream system as funded by ...

PAPI is a widely used portable library for accessing hardware counters on modern microprocessors. PAPI offers both counting and sampling interfaces, but the sampling interface is extremely limited, consisting of a simple interrupt-driven interface that ...

Computational and data scientists at universities have different job resource requirements. Most universities maintain a set of shared resources to support these computational needs. Access to these resources are often free and the access policy is ...

XSEDE users, science gateways, and services need a variety of accurate information about XSEDE resources so that they can use those resources effectively. They need information to decide which resources to use, to track their usage of resources, and to ...

In this paper we give a brief overview of the three projects that were chosen for XSEDE-PRACE collaboration in 2014. We begin this paper with an introduction of the XSEDE and PRACE organizations and the motivation for a collaborative effort between ...

Online training materials, such as the Cornell Virtual Workshop^SM have many advantages, the foremost being that they are always available as a 24x7 option for learners who want to study a topic on demand and at their own pace. It can be challenging to ...

This paper reports on a hands-on workshop that was organized to promote the usage of the national CyberInfrastructure (CI) amongst non-traditional High Performance Computing (HPC) users. The majority of the workshop participants were students and ...

Extending expertise in parallel computing is critical to all those using high performance computing to gain insights into science and engineering problems. Many campuses do not offer such a course because of course load limits, a lack of faculty ...

In the Quadratic Assignment Problem (QAP), n units (usually departments, machines, or electronic components) must be assigned to n locations given the distance between the locations and the flow between the units. The goal is to find the assignment that ...
