Re: [openstack-hpc] What's the state of openstack-hpc now?

Hi, Apologies for top-posting but I don't intend to answer all the historical project points you've raised. Regarding old things floating around on github, your mileage may vary, but I doubt at this point you want to be looking at any of that in great detail. You haven't really explained what you mean by or want from HPC in this context, so I'm guessing a little based on your other questions... OpenStack is many things to different people and organisations, but at the software core is a very flexible infrastructure provisioning framework. HPC requires infrastructure (compute, network, storage), and OpenStack can certainly deliver it - make your deployment choices to suit your use-cases. A major choice would be whether you will use full system virtualisation or bare-metal or containers or <insert next trend> - that choice largely depends on your typical workloads and what style of cluster you want. Beyond that, compared to "typical" cloud hardware - faster CPUs, faster memory, faster network (probably with much greater east-west capacity), integration of a suitable parallel file-system. However, OpenStack is not a HPC management / scheduling / queuing / middleware system - there are lots of those already and you should pick one that fits your requirements and then (if it helps) run it atop an OpenStack cloud (it might help, e.g., if you want to run multiple logical clusters on the same physical infrastructure, if you want to mix other more traditional cloud workloads in, if you're just doing everything with OpenStack like the other cool kids). There are lots of nuances here, e.g., where one scheduler might lend itself better to more dynamic infrastructure (adding/removing instances), another might be lighter-weight for use with a Cluster-as-a-Service deployment model, whilst another suits a multi-user managed service style cluster. I'm sure there is good experience and opinion hidden on this list if you want to interrogate those sorts of choices more specifically. Most of the relevant choices you need to make with respect to running HPC workloads on infrastructure that is provisioned through OpenStack will come down to your hypervisor choices. My preference for now is to stick with the OpenStack community's most popular free OS and hypervisor (Ubuntu and KVM+Libvirt) - when I facilitated the hypervisor-tuning ops session at the Vancouver summit (with a bunch of folks interested in HPC on OpenStack) there was no-one in the room running a different hypervisor, though several were using RHEL. With the right tuning KVM can get you to within a hair's breadth of bare-metal performance for a wide range of CPU, memory and inter-process comms benchmarks, plus you can easily make use of PCI passthrough for latency sensitive or "difficult" devices like NICs/HCAs and GPGPUs. And the "right tuning" is not really some arcane knowledge, it's mainly about exposing host CPU capabilities, pinning vCPUs to pCPUs, and tuning or pinning and exposing NUMA topology - most of this is supported directly through OpenStack-native features now. To answer the GPU question more explicitly - yes you can do this. Mainly you need to ensure you're getting compatible hardware (GPU and relevant motherboard components) - most of the typical GPGPU choices (e.g. K80, K40, M60) will work, and you should probably be wary of PCIe switches unless you know exactly what you're doing (recommend trying before buying). At the OpenStack level you just define the PCI devices you want OpenStack Nova to provision and you can then define custom instance-types/flavors that will get a GPU passed through. Similar things go for networking. Lastly, just because you can do this doesn't make it a good idea... OpenStack is complex, HPC systems are complex, layering one complicated thing on another is a good way to create tricky problems that hide in the interface between the two layers. So make sure you're gaining something from having OpenStack in the mix here.

CfP 11th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '16)
by VHPC 16 18 Mar '16

18 Mar '16

==================================================================== CALL FOR PAPERS 11th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '16) held in conjunction with the International Supercomputing Conference - High Performance, June 19-23, 2016, Frankfurt, Germany. ==================================================================== Date: June 23, 2016 Workshop URL: http://vhpc.org Paper Submission Deadline: April 25, 2016 Call for Papers Virtualization technologies constitute a key enabling factor for flexible resource management in modern data centers, and particularly in cloud environments. Cloud providers need to manage complex infrastructures in a seamless fashion to support the highly dynamic and heterogeneous workloads and hosted applications customers deploy. Similarly, HPC environments have been increasingly adopting techniques that enable flexible management of vast computing and networking resources, close to marginal provisioning cost, which is unprecedented in the history of scientific and commercial computing. Various virtualization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple underutilized 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; OS-level virtualization (i.e., containerization), with its capability to isolate multiple user-space environments and to allow for their coexistence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; I/O Virtualization allows physical NICs/HBAs to take traffic from multiple VMs or containers; 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; the increasingly adopted paradigm of Software-Defined Networking (SDN) promises to extend this flexibility to the control and data planes of network paths. Topics of Interest The VHPC program committee solicits original, high-quality submissions related to virtualization across the entire software stack with a special focus on the intersection of HPC and the cloud. Topics 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 - QoS and SLA in hypervisors and network virtualization - Cloud based network and system management for SDN and NFV - Management, deployment and monitoring of virtualized environments - Virtual per job / on-demand clusters and cloud bursting - Performance measurement, modelling and monitoring of virtualized/cloud workloads - Programming models for virtualized environments - Virtualization in data intensive computing and Big Data processing - 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 - 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 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, plus lightning talks that are limited to 5 minutes. Presentations may be accompanied by interactive demonstrations.
