Reducing the Human Cost of Grid Computing With GlideinWMS
The switch from dedicated, tightly controlled compute clusters to a widely distributed, shared Grid infrastructure has introduced significant operational overheads. If not properly managed, this human cost could grow to a point where it would undermine the benefits of increased resource availability of Grid computing. The glide in WMS system addresses the human cost problem by drastically reducing the number of people directly exposed to the Grid infrastructure. This paper provides an analysis of what steps have been taken to reduce the human cost problem, alongside the experience of glide in WMS use within the Open Science Grid.
