Move from TRIUMF to SFU (30km). Still operated by TRIUMF T1 personnel.
Wigner remote site decommissioning
Analysis of low utilization. ATLAS jobs vary in CPU efficiency from 40% to 90%.
Implemented backfilling with ATLAS@home (BOINC).
IPv6-only worker node still not working but getting closer (no USCMS factory support for IPv6 yet).
Brian Bockelman no longer with us.
HTCondor cluster runs jobs inside docker images managed by RAL. Running latest mainline Linux kernels for best overlayfs support.
4kcore Openstack cloud to double in 2019Q2.
New research division for astroparticle physics, headed by Christian Stegmann.
New computing facility, passively cooled racks
Upgrade to Windows 10: No DESY accounts or information in Microsoft Clouds
Consolidation of cluster management and provisioning to have a more consistent end-user experience and simplify staff effort.
Mostly same as before (i.e. still bad).
Interesting suggesting: e-mail detonation chambers.
Also: check for Monero outgoing links on clusters.
How to break things with a few small UDP packets.
Take home message: pay attention to the ASICS vendors and don't mix 100 Gbit and 40 Gbit.
7 PiB Ceph cluster spanning three sites; dynamic user enrollment through Grouper and COmanage.
oVirt virtualization cluster with Gluster underneath ; SR-IOV (single root input/output virtualization) to virtualize I/O to Infiniband.
no live migration though.
Still wants to phase out AFS before RUN3.
The HS06 benchmark is obsolete, evaluating CPU Spec2017. Experiment-based benchmarks look promising; they use LHC workloads (other contributions are welcome).
A closer look at the realities of pledges, quota and the throughput at the intermediate time scale \(O(\text{days})\)
On-demand provisioning and elastic scaling at CERN.
New experiments bring challenges to computing and processing
Still a factor of 2 gap between requirements for HL LHC and available resources.
Recent market developments:
Gregory Parker, Former WD, now independent contractor.
Adjustments to computing model to get the most out of AWS; use of spot pricing.
(Also: why do HDDs even work these days?)
Lots of science got done for OSG IceCube.
