Coupled Multi-Physics simulations, such as hybrid CFD-MD simulations, represent an increasingly important class of scientific applications. Often the physical problems of interest demand the use of high-end computers, such as TeraGrid resources, which are often accessible only via batch-queues. Batch-queue systems are not developed to natively support the(More)
The e-AIRS[1,2], an abbreviation of 'aerospace integrated research system', is a virtual organization designed to support the aerospace engineering processes on the e-Science environment. As the first step toward the virtual aerospace engineering organization, the e-AIRS targets to give full supports to aerodynamic research processes. Currently, the e-AIRS(More)

E-mail address: vgan@tu-sofia.bg Abstract This activity with the project PRACE-2IP is aimed to investigate and improve the performance of multiple sequence alignment software ClustalW on the supercomputer BlueGene/Q,(More)
In this paper is proposed optimization, scaling, performance evaluation and profiling of parallel multiple sequence alignment based on ClustalW algorithm on the supercomputer BlueGene/Q, so-called JUQUEEN, for the case study of the influenza virus sequences. For this purpose a parallel I/O interface for simultaneous and independent access to single file(More)
e-AIRS, an abbreviation of 'e-Science Aerospace Integrated Research System', is a virtual organization designed to support the aerospace engineering processes on the e-Science environment. Through the collaborative work between aerospace researchers and computer scientists, e-AIRS web portal with the full services on aerodynamic research process is devised.(More)
Cactus is a general-purpose application framework that has been widely used in many application domains. However, it is yet to attract the attention of main stream CFD researchers. We assume that this is mainly due to a lack of concrete guidelines for CFD code porting and development. This motivated us to (1) design a standard CFD toolkit, (2) develop(More)
