The vision of creating a "virtual supercomputing" environment to solve large-scale scientific problems has largely been facilitated by the development and deployment of Grid middleware. However, with the deployment of multiple disconnected Grid ...

BioVLab gateway is built upon Open Gateway Computing Environments and is currently used as reconfigurable cloud computing workbench. In this talk, we will discuss the new directions towards a TeraGrid Science Gateway and experiences and technical ...

Parameter optimization for chemical systems requires generation of initial guesses. These parameters should be generated using systematic sampling of parameter space, minimizing differences between output data and the corresponding reference data. In ...

Current grid security solutions are based on public key infrastructure (PKI). While PKI offers strong security for VPH projects, it suffers from serious usability shortcomings in terms of end-user acquisition and management of credentials which deter ...

Today scientists and engineers are commonly faced with the challenge of modelling, predicting and controlling multiscale systems which cross scientific disciplines and where several processes acting at different scales coexist and interact. Such ...

Traditionally, Hadoop is run on parallel machines with modest processing capabilities and large amounts of disk. A large shared-memory system may not, at first blush, seem a likely host for a Hadoop cluster, but when researchers asked to run Hadoop on ...

This abstract describes the aggregation of TeraGrid and Open Science Grid to run the SCEC CyberShake application faster than on TeraGrid alone. Because the resources are distributed and data movement is required to use more than one resource, a careful ...

The NSF DataONE [1] DataNet project and the NSF Tera-Grid [2] project have initiated a pilot collaboration to deploy and operate the DataONE Member Node software stack on TeraGrid infrastructure. The appealing feature of this collaboration is that it ...

The rapid acquisition of mutations conferring resistance to particular drugs remains a significant cause of anti-HIV treatment failure. Informatics based techniques give resistance scores to individual mutations which can be combined additively to ...

The neoGRID is under development in Quarry, a virtual hosting environment, for working with Taverna-based workflow utilizing grid computing. Taverna is a graphical workbench often used for biomedical informatics [1, and the references therein]. neoGRID ...
