� Improve the performance of openModeller

− Parallelism;

− Cluster (node: multi-core architecture);

− Infiniband;

� Enable the use of cluster power processing on openModeller Desktop;

Workshop Open Modeller - Cluster

� Condor:

− Specialized workload management system for compute-intensive jobs.

� LAM-MPI:

− LAM (Local Area Multicomputer) an open source implementation of the Message Passing Interface (MPI) standard. The MPI standard is the de facto industry standard for parallel applications.

� SOA (Service Oriented Architecture):

− Architectural model to enable the integration of loosed coupling systems.

Workshop Open Modeller - Cluster

� Integration with openModeller desktop using web services;
