The Grid world (which until recently had too much time and money on its hands) has developed various graphical "workflow management systems", that provide a GUI for building big graphs of interconnected applications. With a few clicks you can submit zillions of jobs, with dependencies (e.g., the outputs of jobs A and B are the inputs to C).
Condor provides a mechanism (DAGMan) for defining dependencies, but without the GUI. BOINC's interfaces for submitting and handling jobs are lower level than these. You need to write code (a work generator and assimilator) to do anything, and if you have dependencies you need to implement the logic yourself (i.e., your assimilator would notice that both A and B are done, and submit C). The right approach here is not to develop workflow tools for BOINC, but to extend existing tools so that they can use BOINC as a back end (in addition to Condor, Globus etc.) _______________________________________________ boinc_dev mailing list [email protected] http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev To unsubscribe, visit the above URL and (near bottom of page) enter your email address.
