I've been thinking about the problem of job submission and the tendency of head nodes to become bottlenecks, both in bandwidth and cycles. I also know that many of the batch management systems out there can be installed on the desktop for direct submission. Sadly, some animals are more equal than others and some installations are easier to configure and support than others. Since I don't have control over desktop installs and the technical support can vary in quality, making things really simple is a good thing. I'd appreciate feedback from people who have submission-only clients (or whatever term your package uses) on heterogeneous desktop environments, expressing how well it works with your clusters, how hard the installations and configuration were. and how it was accepted by the user community. If people don't want to post here, I'll accumulate the posts and summarize, though I'd love to see some discussion here.
