The solution provides excellent providing a data repository of up to 1.4PB in a 4U storage rack. availability and medium performance at a very low TCO. The 2 tiers of Minimum configuration is 24 HDDs, providing an upgrade roadmap storage allow data to be moved in real time to an appropriate storage of up to 60 drives. If an additional performance tier is required, it is layer that always provides the right performance at the right time for possible to install up to 24 SAS/SATA SSDs. any data set. The DataCore SANSymphony software requires both DataCore To create а high-performance multi-tiered storage solution, it takes SANsymphony EN-Node licenses (free to request and download) and two mirrored server nodes with SATA (OS boot) and NVMe SSDs (data at maximum 904 Datacore TB Capacity license.

Our information hiding (IH) at the physical layer of a Solid proposed solution is 100% filesystem and OS-independent, State Drive (SSD) NAND flash memory. SSDs, like providing a lot of flexibility in implementation. Note that HDDs, require a mapping between the Logical Block throughout this paper, the term “physical layer” refers Addressing (LB) and physical media. However, the to the physical NAND flash memory of the SSD, and mapping on SSDs is significantly more complex and is handled by the Flash Translation Layer (FTL). FTL readers should not confuse it with the Open Systems is implemented via a proprietary firmware and serves Interconnection (OSI) model physical layer. to both protect the NAND chips from physical access Traditional HDDs, since their advent more than 50 as well as mediate the data exchange between the years ago, have had the least advancement among storage logical and the physical disk.

Survey and Benchmarking of Machine Learning Accelerators
1 Survey and Benchmarking of Machine Learning Accelerators Albert Reuther, Peter Michaleas, Michael Jones, Vijay Gadepally, Siddharth Samsi, and Jeremy Kepner MIT Lincoln Laboratory Supercomputing Center Lexington, MA, USA freuther,pmichaleas,michael.jones,vijayg,sid,[email protected] Abstract—Advances in multicore processors and accelerators components play a major role in the success or failure of an have opened the flood gates to greater exploration and application AI system. of machine learning techniques to a variety of applications. These advances, along with breakdowns of several trends including Moore’s Law, have prompted an explosion of processors and accelerators that promise even greater computational and ma- chine learning capabilities. These processors and accelerators are coming in many forms, from CPUs and GPUs to ASICs, FPGAs, and dataflow accelerators. This paper surveys the current state of these processors and accelerators that have been publicly announced with performance and power consumption numbers. The performance and power values are plotted on a scatter graph and a number of dimensions and observations from the trends on this plot are discussed and analyzed. For instance, there are interesting trends in the plot regarding power consumption, numerical precision, and inference versus training. We then select and benchmark two commercially- available low size, weight, and power (SWaP) accelerators as these processors are the most interesting for embedded and Fig. 1. Canonical AI architecture consists of sensors, data conditioning, mobile machine learning inference applications that are most algorithms, modern computing, robust AI, human-machine teaming, and users (missions). Each step is critical in developing end-to-end AI applications and applicable to the DoD and other SWaP constrained users. -
