Proof of concept data logger for non-active power
… the digital signal processing. The software uses direct memory access and high speed data capture to allow enough time to perform the new general power theory proposed by Gaunt and Malengret [1]. The results are tested to ensure there is no data corruption and basic calibration is performed. The …

A Full System Co-Simulation Platform for Evaluating Edge Machine Learning Inference Using Compute-in-Memory
… machine learning (ML) inference using compute-in-memory (CIM). CIM architectures aim to reduce data movement overhead by performing matrix operations in memory, but end-to-end benefits depend on system-level integration costs that are difficult to assess with isolated hardware models alone. To …

Delegation for Multi-Threaded and Rack-Scale Software
… object to a single designated owner instead of accessing the object directly. Because only the owner thread ever mutates the object, no locks are needed, other threads interact with it by sending requests. This avoids data races, simplifies reasoning, and can outperform lock-based designs by …

A comparison of process and memory-based theories of automaticity
Process and memory-based theories of automaticity are contrasted by manipulating the information contained in primary memory. Process-based theories predict that performance will be modulated by the information contained in primary memory, while memory-based theories predict that performance which …

Accelerating messages by avoiding copies using RDMA in an asynchronous parallel runtime system
… One sided communication with the help of Remote Direct Memory Access (RDMA) supported hardware is the natural choice for large messages as it has proven to provide reduced latencies and increased bandwidth for large payloads in High Performance Computing (HPC) networks. Using RDMA technology …

Verification of DMAC Device Driver Operations in HOL4
… require efficient data transfers involving memory in order to get the best possible performance. However, even the most optimized CPUs take too long to access memory regions, which takes time away from doing the typical computations that a CPU is designed to do. To solve this, Direct Memory …

Modeling and Synthesis of Linux DMA Device Drivers using HOL4
Efficient memory access is critical for computing systems, yet the CPU's management of data transfers can create bottlenecks. To counter this, most advanced high-throughput systems utilize Direct Memory Access (DMA) controllers, where peripherals (such as network interfaces and USB devices) can …

Building a columnar database on shared main memory-based storage
… a shared-nothing architecture. In contrast, main memory-based parallel database management systems are dominated solely by the shared-nothing approach as it preserves the in-memory performance advantage by processing data locally on each server. We argue that this unilateral development is going …
