Petaflop in a Cabinet
The SGI Prism XL is SGI's latest entry into the Exascale race, delivering up to a Petaflop of compute in a single cabinet. The platform was designed to reduce the number of racks and infrastructure required to solve the world's toughest problems, and also has the ability to grow out to 10s or even 100s of Petaflops of compute capability.
Best-of-Breed Platform for 100s to 1000s of PCIe Slots
SGI Prism XL's innovative platform leverages optimized PCIe infrastructure and is uniquely designed starting with the PCI slot and then crafted with enough I/O and memory for a complete system. This sets the platform apart from other accelerator and GPU-capable systems that are designed first with a two-socket server motherboard in mind, with one or more PCIe slots populated with GPU's, or those that use an external chassis plugged into one or more standard rackmount servers.
SGI Prism XL is designed for customers that want to commit to an accelerator-focused architecture for either research or are already in production using accelerator technologies. The motherboard functions almost solely as a high-speed path to off-accelerator memory, I/O and networking.
STIX™ Architecture — Accelerator-Agnostic and Future-Proofed
SGI Prism XL is built around SGI's STIX Architecture which allows an accelerator-agnostic system 'future-proofed' for the next wave of accelerator options and SoC ("System on a Chip") technologies anticipated in the future. Accelerators can be mixed and matched within the same infrastructure, ending the wasteful accelerator-specific infrastructure that we see so often on the market today. SGI Prism XL supports NVIDIA and AMD GPU-based accelerators, as well as Tilera's TileEncore cards. It is also ready to support any common accelerator in demand.
The system is built based upon a "stick" as an integral unit and each stick contains two 'slices' that consist of a full-length, full-height PCIe gen 2 x 16 slot and a single-socket AMD 4100-powered motherboard. Built-in fans and an auto-sensing power supply detect changes in the ambient conditions and keep the unit operating in most environments. Each 'slice' has up to two 2.5 in SATA drives leading to 4 terabytes of storage on a single stick and up to two solid-state drives (SSDs) for additional storage. There are two available GigE ports and each SGI Prism XL is equipped with a fully-configured fat-tree GigE network.
Leading Open Software Architecture
SGI's Accelerator Execution Environment (AEE) drives the run-time environment, bundling tools, libraries and drivers into a package for ease-of-use. Cuda, OpenCL, and TIlera MDE programming environments are supported. SGI Prism XL is managed via SGI Management Center so that a hybrid computing environment made up of various different types of SGI platforms can be managed from a single interface. From a job management perspective, the system can be bundled with Altair PBSprofessional with specific GPU-acceleation features.
Storage and Service Options to Finalize the Solution
SGI Prism XL has multiple storage options, including up to 4 TB of standard 2.5 in. SATA drives local to the stick, and solid-state drive options as well. Block and file level storage options are available Lustre-, MCIS-, and iSCSI-based, all interfacing via high-bandwidth, low-latency Infiniband to the SGI Prism XL.
SGI Prism XL ships with a standard three-year return-to-factory warranty. Warranty upgrades, installation, code porting and tuning services are also available to complete the solution.
