    A Unified Memory Network Architecture for In-Memory Computing in Commodity Servers Jia Zhan∗, Itir Akgun∗, Jishen Zhao†, Al Davis‡, Paolo Faraboschi‡, Yuangang Wang§, and Yuan Xie∗ ∗University of California, Santa Barbara †University of California, Santa Cruz ‡HP Labs §Huawei Abstract—In-memory computing is emerging as a promising largely residing in main memory, they also pose significant paradigm in commodity servers to accelerate data-intensive challenges in DRAM scaling, especially for memory capacity. processing by striving to keep the entire dataset in DRAM. To If the large dataset cannot fit entirely in memory, it has to address the tremendous pressure on the main memory system, discrete memory modules can be networked together to form a be spilled to disk, thus causing sub-optimal performance due memory pool, enabled by recent trends towards richer memory to disk I/O contention. Unfortunately, with the current DDRx interfaces (e.g. Hybrid Memory Cubes, or HMCs). Such an inter- based memory architecture, the scaling of DRAM capacity memory network provides a scalable fabric to expand memory falls far behind the growth of dataset size of in-memory capacity, but still suffers from long multi-hop latency, limited computing applications [12]. A straightforward approach to bandwidth, and high power consumption—problems that will continue to exacerbate as the gap between interconnect and increase memory capacity is to add more CPU sockets for transistor performance grows. Moreover, inside each memory additional memory channels. However, this will introduce module, an intra-memory network (NoC) is typically employed to significant hardware cost [13].

One AMD Place Sunnyvale, CA 94088 Page 1 Introduction to AGP-8X May 10, 2002 W H I T E P A P E R Background Tremendous efforts have been made to improve computing system performance through increases in CPU processing power; however, I/O bottlenecks throughout the computing platform can limit the system performance. To eliminate system bottlenecks, AMD has been working with industry leaders to implement innovative technologies including AGP, DDR SDRAM, USB2.0, and HyperTransport™ technology. This white paper will provide an overview of the latest graphics subsystem innovation: AGP-8X. Introduction The Accelerated Graphics Port (AGP) was developed as a high-performance graphics interface. It alleviates the PCI graphics bottleneck by providing high bandwidth throughput and direct access to system memory. The new AGP3.0 specification adds an 8X mode definition, which doubles the maximum data transfer rate from the previous high reached with AGP-4X by doubling the amount of data transferred per AGP bus cycle. Figure 1 shows the graphic interface bandwidth performance evolution from PCI to AGP-8X. In this figure, AGP3.0 refers to the specific AGP interface specification. AGP-1X, AGP-2X, AGP-4X and AGP-8X represent the data transfer speed mode.

  • 2.2 Memory Hierarchies for Reconfigurable
    Computer Engineering 2010 Mekelweg 4, 2628 CD Delft The Netherlands http://ce.et.tudelft.nl/ MSc THESIS General Purpose Computing with Reconfigurable Acceleration Anthony Arthur Courtenay Brandon Abstract In this thesis we describe a new generic approach for accelerating software functions using a reconfigurable device connected through a high-speed link to a general purpose system. In order for our solu- tion to be generic, as opposed to related ISA extension approaches, we insert system calls into the original program to control the re- configurable accelerator using a compiler plug-in. We define specific mechanisms for the communication between the reconfigurable de- vice, the host general purpose processor and the main memory. The reconfigurable device is controlled by the host through system calls provided by the device driver, and initiates communication by raising interrupts; it further has direct accesses to the main memory (DMA) operating in the virtual address space. To do so, the reconfigurable device supports address translation, while the driver serves the de- vice interrupts, ensures that shared data in the host-cache remain coherent, and handles memory protection and paging. The system is implemented using a machine which provides a HyperTransport CE-MS-2010-28 bus connecting a Xilinx Virtex4-100 FPGA to the host. We evaluate alternative design choices of our proposal using an AES application and accelerating its most computationally intensive function. Our experimental results show that our solution is up to 5 faster than × software

  • Unlocking Bandwidth for Gpus in CC-NUMA Systems
    Appears in the Proceedings of the 2015 International Symposium on High Performance Computer Architecture (HPCA) Unlocking Bandwidth for GPUs in CC-NUMA Systems Neha Agarwalz ∗ David Nellansy Mike O’Connory Stephen W. Kecklery Thomas F. Wenischz University of Michiganz NVIDIAy [email protected], fdnellans,moconnor,[email protected], [email protected] Abstract—Historically, GPU-based HPC applications have had a substantial memory bandwidth advantage over CPU-based workloads due to using GDDR rather than DDR memory. How- ever, past GPUs required a restricted programming model where 0 application data was allocated up front and explicitly copied into GPU memory before launching a GPU kernel by the programmer. Recently, GPUs have eased this requirement and now can employ !"#$% &'! on-demand software page migration between CPU and GPU memory to obviate explicit copying. In the near future, CC- NUMA GPU-CPU systems will appear where software page migration is an optional choice and hardware cache-coherence can also support the GPU accessing CPU memory directly. 0 In this work, we describe the trade-offs and considerations in relying on hardware cache-coherence mechanisms versus using software page migration to optimize the performance of memory- $ "#( %#)$*# &!#+# # intensive GPU workloads. We show that page migration decisions based on page access frequency alone are a poor solution and that a broader solution using virtual address-based program locality to enable aggressive memory prefetching combined with bandwidth balancing is required to maximize performance.
