Scientific workflow orchestration interoperating HTC and HPC resources

In this work we describe our developments towards the provision of a unified access method to different types of computing infrastructures at the interoperation level. For that, we have developed a middleware suite which bridges not interoperable middleware stacks used for building distributed computing infrastructues, UNICORE and gLite. Our solution allows to transparently access and operate o...

Highly Dynamic Workflow Orchestration for Scientific Applications

Scientific applications executed with modern distributed technologies tend to be computed on various, dispersed resources, and workflows become a natural method of describing them. This method of the functional application decomposition allows for fully manual design only to a certain level of complexity. However, the scientific simulations usually expose non-trivial processing logic including ...

Understanding User Behavior: From HPC to HTC

In this paper, we investigate the differences and similarities in user job submission behavior in High Performance Computing (HPC) and High Throughput Computing (HTC). We consider job submission behavior in terms of parallel batch-wise submissions, as well as delays and pauses in job submission. Our findings show that modeling user-based HTC job submission behavior requires knowledge of the und...

High Performance Grid Computing: getting HPC and HTC all together

Wrapping and Interoperating Bioinformatics Resources Using

Bioinformaticians seeking to provide services to working biologists are faced with the twin problems of distribution and diversity of resources. Bioinformatics databases are distributed around the world and exist in many kinds of storage forms, platforms, and access paradigms. To provide adequate services to biologists, these distributed and diverse resources have to interoperate seamlessly wit...
