Given that proxy-certs are typically only valid for 48hr does anyone know. Is there any support for running ~7day jobs via the DIRAC system? Or, Is there any potential of this being supported in the future? * I had a quick look through the maxCPUTime entries in the DIRAC config and I see that Manchester advertises a very long (multi-year(?)) parameter here, but most appear to be around the 48hr walltime. As a worst-case scenario our back-end batch-system at Edinburgh supports running weeklong jobs. However, that means users having to split their job management between 2 systems and must become more involved in topics such as data-management, which I'd rather avoid if possible. Thanks for any help, Rob *PS: This isn't the first time I've heard this come up in a conversation when discussing grid-use with non-LHC communities so I'm not sure if there is a plan here. The style of workflow seems to be like what LSST users were seeing at some point in the past. Most jobs are well defined and short lived, but a small percentage of jobs, which can't be broken down smaller, take a very long time to process. When this is combined with the fact, they can't be identified ahead of time these prove difficult to handle.
