Kalray is a fabless semiconductor company specialized in the application of MPPA manycore technology to high-performance processing. It targets two main markets: networking and storage infrastructure in data centers; and high-performance embedded computing for critical applications.

Kalray was created in 2008 as a spin-off from the CEA. It is headquartered in Grenoble (France), has about 70 employees (50 of which in engineering and R&D) and has 3 other office locations: Sophia Antipolis (France), Los Altos, California (USA) and Tokyo (Japan). Its customers are system integrators and equipment manufacturers for data centers, automotive, defense and aerospace.

MPPA manycore processors

MPPA® manycore processors are composed of clusters of 16 VLIW cores each. A high-speed network on chip is used to interconnect clusters. The MPPA core implements a 5-issue VLIW architecture that provides strong timing predictability properties while delivering scalar performances competitive with high-end superscalar application processors.

MPPA processors can be programmed using a Software Development Kit[2] that encompasses the GNU toolchain, supporting standard programming environment for C and C++ with OpenMP, OpenCL[3].

Neural network inference applications are supported by a fully automatic code generator called KaNN that takes trained neural networks described in Caffe or TensorFlow and produces optimized C code for low-latency inference.

MPPA-256 Andey

Produced in 2013 in CMOS 28HP technology from TSMC, this processor running at 400 MHz has been designed as a target for a cyclostatic dataflow language called Sigma-C.

MPPA2-256 Bostan

Produced in 2015 with the same CMOS 28HP technology from TSMC, this processor running at 550 MHz was enhanced to increase the floating-point performance of the VLIW cores, to natively support the Linux operating system, and to process high-speed Ethernet (up to 80Gbps). Each VLIW core was extended with a tightly coupled cryptographic coprocessor for security protocol acceleration.

MPPA2.2-256 Bostan2

Produced in 2017, this processor is based on the previous generation, Bostan, with an improved DDR controller, Ethernet controller and PCIe controller. As a result, this processor fully supports the NVM Express® (NVMe™) standard interface (for connecting hosts to PCIe bus-attached SSDs), and also the NVMe over Fabrics standard using RDMA (for connections between servers, storage controllers, and NVMe enclosures).

MPPA3 Coolidge

The 3rd-generation MPPA processor Coolidge has been announced[4], which is scheduled for tape-out in TSMC CMOS 16FFC technology by the end of 2018. This processor will include 80 64-bit VLIW processing cores distributed among 5 clusters, 8x 25Gbps Ethernet and 16x PCIe Gen4 interfaces. Each VLIW core is extended with a tightly coupled tensor co-processor for deep learning application acceleration.

Product history

The first Kalray patent was filed in 2010. Today the company holds 23 patent families, including 2 families with an exclusive CEA license.

On 22 June 2015, Kalray began the distribution of data center acceleration board families: TurboCard and KONIC[5], for networking and storage applications, both of which can be programmed with either standard C or C++.[6] TurboCard and KONIC both utilize the MPPA2-256 Bostan 2nd generation processor.

In 2018, the Kalray solutions were certified by the NVM Express organization[7] through the University of New Hampshire InterOperability Laboratory (UNH-IOL)[8], an independent testing provider of standard conformance solutions and multi-vendor interoperability. This certification was the first of its kind for a fully integrated system[9].

Listing on Euronext

In 2017, ahead of the launch of Kalray's third-generation microprocessor, Safran[10] and Pengpai joined the company's historical investors (mainly CEA Investissement, ACE, INOCAP).[11] In 2018, Alliance Ventures (strategic venture capital fund operated by Renault-Nissan-Mitsubishi[12]) and Definvest (an investment fund managed by Bpifrance [13] on behalf of the French Ministry of Armed Forces) also acquired stakes in Kalray[14].

On June 12, 2018, Kalray launched its IPO on the Euronext Paris Stock Market[15] and raised €47.7M (after exercise of the over-allocation option), "the most significant IPO since Euronext Growth was created in Paris"[16].
