Building and Managing Business Resiliency on the Cloud (Tuesday Dec. 8th starts at 1:30pm, Room: Point Grey 3rd Floor)
Abstract: Business resiliency is the ability to rapidly adapt and respond to business disruptions and to maintain continuous business operations. Enterprises are rapidly migrating their workloads to cloud environments to reap the many economic advantages of cloud computing. These enterprises have business resiliency requirements that can be very stringent. Some of the very attributes of cloud architectures that create economic advantages (e.g., logically or physically centralized management and control, and common data management mechanisms) are potential single points of failure and may actually make such outages and failures more likely. The sheer scale of a cloud environment and the concomitant aggregation of a very large amount of workloads into a single site tend to completely overwhelm traditional resiliency technologies.
We will present approaches for providing business resiliency in cloud-based IT infrastructures against unplanned failures ranging from localized hardware and software failures (such as failures of processes, containers, servers, and storage) to large-scale failures such as disasters, as well as planned outages such as those due to maintenance and upgrades.
We will describe the steps involved in formulating, implementing, and operating a business resiliency strategy for cloud-based IT infrastructures, including understanding exactly what the business needs in order to survive unexpected events, assessing risk versus cost, and planning ahead for challenges that could come at any time.
We will present a reference architecture and patterns for business resiliency covering cloud infrastructures and both cloud-enabled and cloud-native applications. The reference architecture provides a formalized approach (including blueprints and patterns/building blocks) for business resiliency, taking into account the capabilities and constraints of different cloud environments and the workloads running on those environments. The reference architecture includes design elements (such as orchestration, replication, monitoring, management) and design principles at each layer of the application stack (e.g., presentation, middleware, data layers) and infrastructure (network, storage, load balancing, monitoring) required to meet the resiliency requirements.
The tutorial will include a survey of commercial cloud resiliency solutions and academic results, and will also cover specific examples on how certain key enabling technologies (including Software Defined Environments, replication technologies, and the use of deep analytics for resiliency planning and assessment) are applied in the framework of the reference architecture to achieve business resiliency. We will also present our own experiences in building and managing cloud systems for business resiliency.

Improving overall performance and energy consumption of your cluster with remote GPU virtualization
Abstract: Nowadays, GPUs are widely used to accelerate scientific applications, but their adoption in HPC clusters presents several drawbacks. First, in addition to increasing acquisition costs, the use of accelerators also increments maintenance and space costs. Second, energy consumption is also increased. Third, GPUs in a cluster may present a relatively low utilization rate (it is quite unlikely that all the accelerators in the cluster are used all the time). In consequence, virtualizing the GPUs of the cluster is an appealing strategy to simultaneously dealing with all these drawbacks. Additionally, cluster throughput is increased whereas costs and energy consumption are reduced. In this tutorial we present the benefits of remote GPU virtualization, comparatively introducing several of these frameworks: gVirtuS, DS-CUDA, and rCUDA. We present the latest developments within these frameworks: low-power processors, job schedulers, virtual machines, etc. In a hands-on part of the tutorial we expose how to install and use the freely available rCUDA solution. We demonstrate how by using rCUDA over a high-performance interconnect the overhead of remote GPU virtualization is reduced to negligible values. Finally, attendees will be able to exercise with this framework by connecting to a real cluster that includes several nodes with GPUs. Presenters:
