netcenter/sans tools have a new home
by Steven Armstrong 03 Jun '14

03 Jun '14

Hi all In case you are using some of my scripts to talk to the netcenter API, the repo finally has a new home: git clone git://hpc-git.ethz.ch/sans.git Or to change an existing local checkout use something like this: git remote set-url origin git://hpc-git.ethz.ch/sans.git Cheers, Steven -- Steven Armstrong, ETH Zurich High Performance Computing, Scientific IT Services SOW H 15, Sonneggstrasse 63, 8092 Zurich, Switzerland Phone +41 44 632 25 24

Anybody interested in a talk about moosefs / lizardfs?
by Steven Armstrong 06 Oct '13

06 Oct '13

Hi all Long time no see, hope you are all fine ;-) One of the developers of lizardfs (formerly moosefs) contacted me. Peter aNeutrino may be in Zurich in October. If anybody else is interested I could ask him to give a talk. moosefs is a rather interesting beast, think of it as a glusterfs alternative that has usable documentation and actually works. We looked at it as a possible solution for cluster scratch space, storage of virtual machine images and archival of project data. The tests were promising, but as my boss is retiring in January 2014 it did not make sense to deploy it. Pity, wish we would have known this 6 years ago ;-) Anyway, maybe of interest for some of you - I guess you have similar problems as we did. Best wishes, Steven BTW: I am looking for a new job as of February 2014. If you hear/know something I'd appreciate a ping. -- Steven Armstrong Institute of Computational Science, ETH Zurich IT Management & Support Universitaetsstrasse 6, CAB/H/88 8092 Zurich, Switzerland Phone: +41 44 632 25 24
