SUPERCOMPUTING THAT RUNS LIKE THE CLOUDSOFTWARE FOR NEW WORKLOADSThe convergence of HPC, AI, and data analytics workloads coupled with explosive data growth have created new requirements for compute, software, networking, and storage. Future supercomputers will need to handle exabytes of data in order to enable modern workloads to run in a productive, reliable, and expedient manner.

Seeing the need for an evolution of supercomputing software infrastructure, Cray designed and developed the Cray Shasta software solution. Built on decades of supercomputing expertise, Shasta software adds the productivity of cloud and data center interoperability to the power of supercomputing to bring you a new standard in manageability, reliability, availability, and resiliency.

Cray Shasta software delivers the ease and flexibility of cloud computing through an environment which supports microservices-

based composability for rapid innovation of new converged workflows across processor architectures. Seamlessly scale from development in the cloud to production on a supercomputer.

With the Cray Shasta software stack you get Cray’s legendary package of HPC-optimized programming tools, Linux OS, and a scalable analytics/AI suite.

Cray’s Linux Environment is a suite of high-performance software designed to run large, complex applications and scale efficiently to more than 500,000 processor cores. Also, many ISV applications are available “out of the box,” benefiting from Cray’s network and MPI libraries.

The Cray Urika AI and analytics software suite unlocks sophisticated insights with a robust set of tools including Apache® Spark™, TensorFlow™, Cray Graph Engine, Python with distributed Dask, PyTorch, Cray Distributed AI plugin, Jupyter Notebooks and many more.

The Cray Shasta software stack can be broadly split into administrator and developer services.

• Systems, network, storage, and application management and monitoring support predictable performance of workflow

• Microservices approach with full separation of management plane from compute plane to allow each to be run and upgraded seamlessly ensuring high resiliency of critical system management software

• REST APIs & standard protocols enable full interoperability with existing monitoring, management, and automation toolsets

• Pre-integrated AI software packages that are current with evolving AI frameworks/tools and tools to Increase data scientist productivity

• Containerized developer environments enable portability from laptop or cloud to supercomputer

• Native support for containers and converged workflow orchestration on Cray’s Linux Environment delivers composability of cloud on hardened supercomputing OS

• Common software stack simplifies systems administration and support for converged scientific and AI workflows

Developer Productivity and Capability. Curated set of flexible and powerful tools to create new converged modeling, simulation, analytics, and AI workflows.

Value at Any Scale. Same features and capabilities through a unified software stack regardless of system size and spanning both liquid-cooled and air-cooled systems.

Operational Excellence. Core supercomputing capabilities combined with new cloud capabilities shifts focus from maintenance to innovation.

Datacenter Interoperability. Open REST APIs for management, access, and integration

Investment Protection. Complete software stack supports a broad range of operating systems and processor options from management to end user development
