Anyone who would like to help out with the session organisation are welcome to add themselves to the Helpers list on https://etherpad.openstack.org/p/YVR-ops-hpc. I’ve had a number of productive discussions in the past summits where cloud/HPC/HTC folk get together and having something very interactive is the aim. Equally, feel free to add topics you’d like to find out if others have found solutions for to the etherpad…. We may not find solutions on the day but getting together people who share the same problems is already a major step forward.

NUMA config
by Blair Bethwaite 05 May '15

05 May '15

Hi all, Just reading over the docs describing NUMA scheduler filter testing (http://docs.openstack.org/developer/nova/devref/testing/libvirt-numa.html#t…) Somewhat confused by the scenario at the end, which seems to call for a guest with 1 NUMA node but looks like it gets created with 2... I'm obviously misunderstanding something in the resultant XML, but there's no topology info shown from inside the guest, so I'm not sure. Anyone tried this? -- Cheers, ~Blairo

CfP Virtualization in High-Performance Cloud Computing Workshop (VHPC '15)
by VHPC 15 24 Apr '15

24 Apr '15

================================================================= CALL FOR PAPERS 10th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '15) held in conjunction with Euro-Par 2015, August 24-28, Vienna, Austria (Springer LNCS) ================================================================= Date: August 25, 2015 Workshop URL: http://vhpc.org Paper Submission Deadline: May 22, 2015 CALL FOR PAPERS Virtualization technologies constitute a key enabling factor for flexible resource management in modern data centers, cloud environments, and increasingly in HPC as well. Providers need to dynamically manage complex infrastructures in a seamless fashion for varying workloads and hosted applications, independently of the customers deploying software or users submitting highly dynamic and heterogeneous workloads. Thanks to virtualization, we have the ability to manage vast computing and networking resources dynamically and close to the marginal cost of providing the services, which is unprecedented in the history of scientific and commercial computing. Docker et al. OS-level virtualization, with its capability to isolate multiple user-space environments allows for their co-existence within the same OS kernel. It promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; coupled with lightweight OSs it forms a potent architecture with promise to become a mainstream environment for HPC workloads. Machine virtualization, with its capability to enable consolidation of multiple under-utilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; I/O Virtualization allows physical network adapters to take traffic from multiple VMs; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology and IP addressing, provides the fundamental ground on top of which evolved network services can be realized with an unprecedented level of dynamicity and flexibility; These technologies have to be inter-mixed and integrated in an intelligent way, to support workloads that are increasingly demanding in terms of absolute performance, responsiveness and interactivity, and have to respect well-specified Service- Level Agreements (SLAs), as needed for industrial-grade provided services. The Workshop on Virtualization in High-Performance Cloud Computing (VHPC) aims to bring together researchers and industrial practitioners facing the challenges posed by virtualization in order to foster discussion, collaboration, mutual exchange of knowledge and experience, enabling research to ultimately provide novel solutions for virtualized computing systems of tomorrow. The workshop will be one day in length, composed of 20 min paper presentations, each followed by 10 min discussion sections, and lightning talks, limited to 5 minutes. Presentations may be accompanied by interactive demonstrations. TOPICS Topics of interest include, but are not limited to: - Virtualization in supercomputing environments, HPC clusters, cloud HPC and grids - OS-level virtualization including container runtimes (Docker, rkt et al.) - Lightweight compute node operating systems/VMMs - Optimizations of virtual machine monitor platforms, hypervisors and - Hypervisor and network virtualization QoS and SLAs - Cloud based network and system management for SDN and NFV - Management, deployment and monitoring of virtualized environments - Performance measurement, modelling and monitoring of virtualized/cloud workloads - Programming models for virtualized environments - Cloud reliability, fault-tolerance, high-availability and security - Heterogeneous virtualized environments, virtualized accelerators, GPUs and co-processors - Optimized communication libraries/protocols in the cloud and for HPC in the cloud - Topology management and optimization for distributed virtualized applications - Cluster provisioning in the cloud and cloud bursting - Adaptation of emerging HPC technologies (high performance networks, RDMA, etc..) - I/O and storage virtualization, virtualization aware file systems - Job scheduling/control/policy in virtualized environments - Checkpointing and migration of VM-based large compute jobs - Cloud frameworks and APIs - Energy-efficient / power-aware virtualization Important Dates April 29, 2015 - Abstract registration May 22, 2015 - Full paper submission June 19, 2015 - Acceptance notification October 2, 2015 - Camera-ready version due August 25, 2015 - Workshop Date TPC CHAIR Michael Alexander (chair), TU Wien, Austria Anastassios Nanos (co-chair), NTUA, Greece Balazs Gerofi (co-chair), RIKEN Advanced Institute for Computational Science, Japan PROGRAM COMMITTEE Stergios Anastasiadis, University of Ioannina, Greece Costas Bekas, IBM Zurich Research Laboratory, Switzerland Jakob Blomer, CERN Ron Brightwell, Sandia National Laboratories, USA Roberto Canonico, University of Napoli Federico II, Italy Julian Chesterfield, OnApp, UK Patrick Dreher, MIT, USA William Gardner, University of Guelph, Canada Kyle Hale, Northwestern University, USA Marcus Hardt, Karlsruhe Institute of Technology, Germany Iftekhar Hussain, Infinera, USA Krishna Kant, Temple University, USA Eiji Kawai, National Institute of Information and Communications Technology, Japan Romeo Kinzler, IBM, Switzerland Kornilios Kourtis, ETH, Switzerland Nectarios Koziris, National Technical University of Athens, Greece Massimo Lamanna, CERN Che-Rung Roger Lee, National Tsing Hua University, Taiwan William Magato, University of Cincinnati, USA Helge Meinhard, CERN Jean-Marc Menaud, Ecole des Mines de Nantes France Christine Morin, INRIA, France Amer Qouneh, University of Florida, USA Seetharami Seelam, IBM Watson Research Center, USA Josh Simons, VMWare, USA Borja Sotomayor, University of Chicago, USA Kurt Tutschku, Blekinge Institute of Technology, Sweden Yasuhiro Watashiba, Osaka University, Japan Chao-Tung Yang, Tunghai University, Taiwan PAPER SUBMISSION-PUBLICATION Papers submitted to the workshop will be reviewed by at least two members of the program committee and external reviewers.

Re: [openstack-hpc] CPU intensive apps on OpenStack
by Blair Bethwaite 23 Apr '15

Hi Tim, What's your reference on disabling EPT? I can find some fairly old stuff on this, but I thought newer processors had improved performance here to lower page fault overheads... so I guess I'm wondering if you've seen a recent evaluation somewhere? Re. NUMA etc, it seems like the most important thing if you're running large memory apps inside your guests is to make sure the guest is pinned (both CPU and NUMA wise) and sees a NUMA topology that matches how it is pinned on the host. I haven't had a chance to try it yet but I thought this was all now possible Juno. Beyond that you probably want the guest kernel to be NUMA sassy as well, so it needs (IIRC) Linux 3.13+ to get the numa_balancing (nee autonuma) goodies. I'm not sure if for such cases you might actually want to disable numa balancing on the host or whether the pinning would effectively remove any overhead there anyway... PS: +1 on the meetup suggestion -- Cheers, ~Blairo

Vancouver meetup ?
by Tim Bell 07 Apr '15

07 Apr '15

Would there be interest in trying to get a session at the ops design summit on HPC ? The sessions are being accumulated at https://etherpad.openstack.org/p/YVR-ops-meetup so I would propose we try to get a small working group on OpenStack HPC into the parallel sessions if there is interest. I have put a few ideas down in the etherpad (search for HPC working group) and feel free to add those items you think would be worth discussing. Tim
