One-click Hadoop Cluster Deployment on OpenPOWER SystemsPradeep Kumar
This document describes how to deploy Hadoop clusters on OpenPOWER systems using OpenStack and the Sahara plugin in 3 steps: 1) Setup OpenStack with Sahara on OpenPOWER servers, 2) Create PowerPC images and node group templates in Sahara, 3) Launch and test a Hadoop cluster from the Sahara dashboard. The deployment was tested on IBM S822L servers running PowerKVM with a 500GB Terasort completing in 7000 seconds on 2 data nodes and 1 name node. Upstream contributions were also made to OpenStack to support PowerPC.
This document introduces a pre-service biology teacher pursuing a MAT degree who is sharing experiences using Second Life to practice teaching skills. The teacher discusses background in evolutionary biology research, transitioning to teaching, current teaching assistantship and short-term sub position, science idols, and hobbies including running, baking, and outdoor activities.
This document discusses a teaching activity about sickle cell anemia. It begins with an introduction to sickle cell anemia and outlines two key activities for students - a "mystery of the crooked cell" activity where students must hypothesize the cause of sickle cell anemia using a case study and lab stations. It concludes with a WHO summit narrative where students present as scientists from different countries on the state of sickle cell anemia and examples of educational materials and experiments they designed. The document explains that the activity engages students by addressing a real-world medical issue through science, collaboration, and problem-solving to help humans.
This document provides a list of topics related to love stories including works by Harold Pinter, role play exercises, critical incidents involving relationships, quotes about beauty and flying, a quote from Robert Burns' poem "My Love is Like a Red, Red Rose", references to Romeo and Juliet and The Ghost of Canterville by Oscar Wilde. It instructs students to read, imagine, write and tell their own love stories to the group using narrative devices and Aristotle's five points of rhetoric.

This document discusses monitoring PowerKVM nodes using the Ganglia and Nagios monitoring systems. It provides an overview of Ganglia and how it can be used to monitor metrics like CPU, memory, disk, and network usage on PowerKVM nodes and their virtual machines. It also discusses how Nagios can monitor PowerKVM hosts and services, how to add PowerKVM nodes to the Nagios server, and examples of host states and performance monitoring that Nagios provides.
QEMU Disk IO Which performs Better: Native or threads?Pradeep Kumar
Pradeep Kumar Surisetty from Red Hat presented a comparison of native and threaded I/O performance in QEMU disk I/O. He outlined KVM I/O architecture, storage transport options in KVM including virtio-blk configurations, and benchmark tools used. Performance testing was done with various disk types, file systems, images and configurations. Native generally outperformed threads for random I/O workloads, while threads sometimes showed better performance for sequential reads, especially with multiple VMs.
Performance Benchmarking of Clouds Evaluating OpenStackPradeep Kumar
Pradeep Kumar surisetty presented on performance benchmarking of clouds and evaluating OpenStack. He discussed key cloud characteristics like elasticity and scalability. He then covered various performance measuring tools like Rally, Browbeat, Perfkit Benchmarker, and SPEC Cloud IaaS 2016 benchmark. He also discussed performance monitoring tools like Ceilometer, Collectd/Graphite/Grafana, and Ganglia. Finally, he provided some tuning tips for hardware, instances, over-subscription, local storage, NUMA nodes, disk pinning, and deployment timings.
This document discusses KVM virtualization and why it is considered the best platform. It states that KVM provides high performance, strong security through EAL4+ certification and SE Linux, and can save customers up to 70% on costs compared to other solutions. It also supports various operating systems and works with Red Hat products like OpenStack and Red Hat Enterprise Virtualization for managing virtualization. Charts are included showing KVM outperforming VMware on benchmark tests using different CPU core counts.
