- Why should BOINC use grids - Resources in general more secure and owners trusted - Can be used for result verification - Resources are more stable, available, and often underutilized - Easier to support low-latency jobs for example - Resources often connected by high bandwidth links - Could support data-intensive or data-parallel jobs - Environment (in terms of software/libraries) tends to be more homogeneous and configurable - Easy to run the BOINC client on a cluster and supercomputers by statically compiling a stand-alone client - Examples: condor pools that run BOINC jobs when their machines are not in use - Leverage existing grid software - Job submission often simpler with web portals - Why should grids use BOINC - Order of magnitude more computing power and storage at fraction of the cost - Many grid jobs are already task parallel, - Challenge - Lack of mechanisms and standards to allow a job submitted on a grid to run easily in BOINC - Cannot rely on the existence of a software stack - Concept of an individual user or job (and access rights) in BOINC - Credit accounting for these jobs
