Hello I've a bio-informatics workflow, that I'm considering running in Kepler. The workflow analyzes about a dozen genomes, and will take a few hundred hours of computing, which I'll run on our 64 node Rocks cluster.
Several Perl programs retrieve the data and analyze it, inputting and outputting results from and to both files and a MySQL database. Each program needs to be instantiated multiple times with different input. It appears that Kepler might be able to execute these computations with its PN scheduler and ExternalExecution Actor, but 1) we typically manage jobs on the cluster via the SGE (qsub) and 2) Kepler's documentation says that "to use the ExternalExecution actor, the invoked application must be on the local computer", which implies that Kepler must be installed on all nodes of the cluster. How would one approach this problem with Kepler? If Kepler isn't the right tool for this problem, what would you recommend? Thanks Arthur Arthur P.
