misc issues

Dear Autonians,

I just updated MATLAB to R2015a on thee computing nodes which were not
busy lov3, low1, charity. LOV3 and LOW1 appear to be in the good shape now
but I still see that network is saturated by careless writing over NFS. At
this point I am not even sure if it is due to the writing on /zfsauton or
/zfsneill as I see bunch of MATLAB and other scripts running across the
servers of both groups. If you have started a job on Thursday afternoon or
Friday please contact me by PM so that we can get to the bottom of this.
Hopping from computing node to computing node and crashing them with
MATLAB scripts or programs has a serious impact to the productivity of
entire LAB. I would be happy to sit with you on Monday and figure out what
is wrong with programs (from systems point of view) and why they are
crashing servers.
