Release of GRID superscalar as Open Source

The GRID superscalar (GRIDSs) project at the Barcelona Supercomputing Center (BSC-UPC, Spain) is pleased to announce the distribution as Open Source of the different components in the GRIDSs programming environment, both for Globus Toolkit 4 (GT4) and SSH/SCP. GRIDSs is distributed under the terms of the Apache License, Version 2.0.

GRIDSs is a Grid-unaware programming environment that allows to program applications in a simple way. These applications will be efficiently run on a computational Grid, as GRIDSs is able to parallelize them, at runtime and at task level. Applications that can specially benefit from GRIDSs are those composed of coarse grained tasks. The environment is composed of a code-generation tool (gsstubgen), the Deployment-Center (which is a graphical tool for Grid configuration setting and application deployment), a powerful runtime library and a monitor. Two versions are currently under distribution: one for GT4 and another for SSH/SCP. While the first one is very well suited for Grids in general, the second one is specially good for Grids of clusters or for single clusters in particular.

Main features of GRID superscalar:

Grid unaware programming model (Grid keeps transparent to the application)
Bindings for C/C++, Java, Perl and shell script
Automatic deployment and Grid configuration maintenance and test (through the Deployment Center)
Automatic parallelization at task level through dynamic data-dependence analysis
Dynamic scheduling and assignment of Grid resources
Data-locality awareness
Automatic file renaming and file transfer handling
Checkpointing
Fault-tolerance
