Multiple scheduling schemes
A fair-share scheduling scheme with 10,000 priority levels can be used for multiple jobs for a single application. Preemptive and resource-threshold-based scheduling is available with runtime change management. Multi-dimensional scheduling is supported with the ability to specify slot definition for each consumer in terms of up to four customizable resource metrics.
Dynamic hybrid cloud
IBM Spectrum Symphony® provides support for a hybrid HPC cloud, enabling workloads to be forwarded to multiple clouds and data to be automatically staged to or from the cloud. Further, resources that are consumed on the cloud can be autoscaled based on workload demands and scheduling policies. IBM Spectrum Symphony is available for fully automated deployment on IBM Cloud. Take advantage of the security and performance of IBM Cloud for your HPC workloads and choose from a wide variety of available IBM Cloud Virtual Servers for VPC to customize your HPC cluster.
The resource-sharing model in IBM Spectrum Symphony helps reduce infrastructure expenses and management costs. It enables you to deploy multiple heterogeneous applications on the same shared grid. At the same time, you can preserve line of business ownership while delivering service-level guarantees.
Built in Hadoop MapReduce-compatible implementation
The IBM Spectrum Symphony Advanced Edition includes an Apache Hadoop-compatible MapReduce implementation optimized for low latency, high reliability and resource sharing. Using this capability, you can run Hadoop and non-Hadoop applications on the same shared distributed infrastructure. The multitenant architecture allows multiple MapReduce engines to be deployed on a single shared infrastructure.
Supports multiple clusters
Multiple cluster support allows a set of resources to span multiple clusters and to be moved between clusters based on need. A single session can run across multiple clusters, both on premises and on the cloud, efficiently managed through a single interface.
Supports rolling upgrades
With rolling upgrades, administrators can easily install and configure a newer version of IBM Spectrum Symphony over an older version without the need for manual migration.
Three editions of IBM Spectrum Symphony
IBM Spectrum Symphony is available in three editions, all featuring low-latency, high-performance computing service-oriented architecture, agile service and task scheduling. The editions range in scalability from one or two hosts for Developer Edition, to up to 5,000 hosts and 128,000 cores for Advanced Edition—your best choice for distributed compute- and data- intensive applications, including Hadoop MapReduce. The Standard Edition offers enterprise-class performance and scalability.
