COMP Superscalar (COMPSs) is a programming framework that provides an easy-to-use programming model and a runtime to ease the development of applications for distributed environments. Thanks to its modular architecture COMPSs can use a wide range of computational infrastructures providing a uniform interface for job submission and file transfer operations through adapters for different middlewares. In the context of the VENUS-C project the COMPSs framework has been extended through the development of a programming model enactment service that allows researcher to transparently port and execute scientific applications in the Cloud.
This paper presents the implementation of a bioinformatics workflow (using BLAST as core program), the porting to the COMPSs framework and its deployment on the VENUS-C platform. The proposed approach has been evaluated on a Cloud testbed using virtual machines managed by EMOTIVE Cloud and compared to a similar approach on the Azure platform and to other implementations on HPC infrastructures.
