Most parallel computing resources are controlled by batch schedulers that place requests for computation in a queue until access to compute nodes is granted. Queue waiting times a...
Grid applications that use a considerable number of processors for their computations need effective predictions of the expected computation times on the different nodes. Currentl...
High performance application development remains challenging, particularly for scientists making the transition to a Grid environment. In general areas of computing, virtual envir...
Using a large HPC platform, we investigate the effectiveness of symbiotic space-sharing, a technique that improves system throughput by executing parallel applications in comb...
As the size of distributed systems keeps growing, the peer to peer communication paradigm has been identified as the key to scalability. Peer to peer overlay networks are charact...

Parallel sequence-search tools are rising in popularity among computational biologists. With the rapid growth of sequence databases, database segmentation is the trend of the futu...
The aIOLi project aims at optimizing the I/O accesses within the cluster by providing a simple POSIX API, thus avoiding the constraints to use a dedicated parallel I/O library. Th...
Fine-Grained Cycle Sharing (FGCS) systems aim at utilizing the large amount of computational resources available on the Internet. In FGCS, host computers allow guest jobs to utili...
