Improving Latency Tolerance of Multithreading through Decoupling

ÐThe increasing hardware complexity of dynamically scheduled superscalar processors may compromise the scalability of this organization to make an efficient use of future increases in transistor budget. SMT processors, designed over a superscalar core, are therefore directly concerned by this problem. This work presents and evaluates a novel processor microarchitecture which combines two paradi...

Quantum Programming for Embedded Systems: Toward a Hassle-Free Multithreading

Even the smallest embedded processor must typically handle a variety of activities and manage multiple devices at the same time. Dealing with the concurrency arising naturally in embedded systems has always been one of the most challenging aspects of embedded systems programming. The time-honored approaches range from simple foreground/background loops (main()+ISR) to RTOS-based preemptive mult...

ACACES A Decoupled Access/Execute Architecture for Mobile GPUs

Smartphones are emerging as one of the fastest growing markets, providing enhanced capabilities every few months. However, supporting these hardware/software improvements comes at the cost of reducing the operating time per battery charge. The GPU is only left with a shrinking fraction of the power budget, but the trend towards better screens will inevitably lead to a higher demand for improved...

Modeling the Parallel Execution of Black-Box Services

Services running in a data center frequently rely on RPCs to child services (e.g. storage, cache, authentication), and their latency depends crucially on latencies of those RPCs. However, even though service latency often comes exclusively from the time spent inside remote calls, it is difficult to determine parent latency since multithreading and asynchronous RPCs lead to complex and non-linea...
