OpenPOWER Overview

Nallatech has been a contributing member of the OpenPOWER Foundation since its founding moment back in 2013. As an open technical membership organization the OpenPOWER Foundation enables data centers to rethink their approach to technology. Member companies are enabled to customize POWER CPU processors and system platforms for optimization and innovation for their business needs. These innovations include custom systems for large or warehouse scale data centers, workload acceleration through GPU, FPGA or advanced I/O, platform optimization for SW appliances, or advanced hardware technology exploitation. OpenPOWER members are actively pursuing all of these innovations and more and welcome all parties to join in moving the state of the art of OpenPOWER systems design forward. OpenPOWER Intro Video.

Nallatech CAPI SNAP Enabled Near-Storage FPGA Accelerator

With the launch of OpenPOWER’s open source CAPI SNAP Framework; Nallatech’s 250S in-memory FPGA accelerator now supports the next level of programmability for developers.

Nallatech 250S - In-Memory FPGA AccelerationThe CAPI SNAP framework consist of an API running in the IBM POWER 8 host and an FPGA Firmware Framework that resides within the FPGA on Nallatech’s 250S in-memory FPGA accerlator card.

The API makes it easy for an application to call an accelerated function. The simple API has three parameters: the source data; the accelerated action to be performed; and the destination for the action output.

The FPGA framework logic implements all of the computer engineering interface logic, data movement, caching, and pre-fetching work–leaving the programmer to focus on their accelerator functionality, or “Action Code” on the FPGA. The framework takes care of retrieving the source data (whether it is in system memory, Local FPGA Memory or NVMe storage). as well as sending the results to the specified destination. The programmer, writing in a high level language such as C/C++ or Go, needs only to write their data transform, or “action code”. Framework compatible compilers translate the high-level language to Verilog, which in turn gets synthesized using Xilinx’s Vivado toolset.

What is CAPI?

IBM developed the Coherent Accelerator Processor Interface (CAPI) as a new means for solution architects to improve system-level performance.

Most FPGA Accelerators utilize PCIe as their link to the host. CAPI provides a unique alternative, allowing the FPGA accelerator to coherently attach to the fabric of a POWER8™ chip and up to 1 TB of system memory.

This new hybrid solution has a simple programming paradigm while delivering algorithm acceleration and performance well beyond what’s available today.

How is Nallatech involved?

Nallatech’s 385 card is the first supported CAPI FPGA accelerator card.

Through our membership in the OpenPOWER™ Foundation, we have collaborated with IBM and Altera to provide the OpenPOWER CAPI Developer Kit for POWER8, which includes everything needed to start developing with CAPI in a POWER8 System.

Nallatech is also working with select partners and OpenPOWER members on custom hardware and CAPI enabled solutions.
