[NLPL Task Force (A)] Saga usage

[Stephan Oepen]

dear both:

it appears you are making good usage of Saga, and that is what we
intend through this nordic partnership.  however, Saga has been very
heavily loaded this summer, and the national administrators are asking
all projects to try and reduce usage, for example cutting out strictly
speaking unnecessary 'bonus' jobs or spreading out their computing
over longer periods of time.

could i kindly ask you to try and scale back the load you put on Saga
a little, in particular aim to not line up too many jobs in the gpu
queue, which practically means other users may find themselves 'locked
out' for extensive wait periods.

arradi: as an MSc student, i would ask that you typically limit your
concurrent gpu usage to at most five active jobs (or, correspondingly,
a maximum of five gpus).  just now, that would mean that you should
terminate or cancel 15 jobs and wait to resubmit these until either
your other jobs have completed, or the gpu queue becomes partly idle.

i am sorry to have to impose such 'soft' usage constraints, but
recently the situation on Saga has been unsatisfactory to some users,
and we need to avoid any impression of individual user communities
getting into the way of others.

with best wishes, oe
