P-GRADE provides a unique and complete solution for development and execution of parallel applications on supercomputers, clusters, and Grid systems. P-GRADE's high-level graphical environment was designed so that the users need not learn programming methodologies for different parallel and distributed platforms; the same environment is applicable for traditional supercomputers, PC clusters, or new Grid solutions (based on either Globus or Condor) to utilise transparently all the available computational resources.

P-GRADE significantly accelerates the reengineering procedure of sequential and legacy programs for parallel and Grid systems providing easy-to-use solutions even for non-professional programmers. The sequential code can be easily inherited and re-used relying on the hierarchical design approach as well as the legacy sequential or parallel programs can interoperate to other jobs with the built-in workflow layer in order to execute large-scale complex programs in the Grid. Each stage of development life-cycle (design, debugging, testing, monitoring and performance analysis) is covered in P-GRADE system and its highly portable run-time environment provides dynamic load balancing facilities for long-running parallel applications and fault tolerant execution based on fully automatic checkpointing and migration mechanisms for cluster and Grid applications as well as on-line monitoring facilities and remote performance visualisation.

P-GRADE development environment together with existing cluster management tools - HPCware - will enable companies to supervise and also utilise their own PC clusters fast and easily as a cost-efficient high performance computing (HPC) platform. Moreover, HPCware with P-GRADE's run-time environment will provide strong support for enterprise-level Grid systems connecting several clusters from different sites of company.
