LRSCwait: Enabling Scalable and Efficient Synchronization in Manycore Systems through Polling-Free and Retry-Free Operation

In this paper, the authors address the issue of polling in shared-memory manycore systems, which leads to contention and inefficiencies. They propose LRwait and SCwait synchronization methods, along with the scalable Colibri implementation, to reduce polling by allowing cores to sleep while waiting. This approach results in a 6.5x improvement in throughput and a 7.1x increase in energy efficiency on a 256-core RISC-V platform, with only a 6% area overhead.

Software-Defined CPU Modes

CPUs contain a compute instruction set, which regular applications use. This paper explores the question, whether CPU modes could be defined entirely by software. Researchers show how such a design would function and explore the advantages it enables. They believe that pushing all existing modes under a common design umbrella would enforce a cleaner structure and more control over exposed functionality. At the same time, the flexibility of software-defined modes enables interesting new use cases.

Dual Vector Load for Improved Pipelining in Vector Processors

Vector processors execute instructions that manipulate vectors of data items using time-division multiplexing (TDM). In this paper, the researchers propose a dual vector load: A parallel or interleaved load of the two input vectors. Their investigation finds that compute-bound and some memory-bound applications profit from this feature when the memory and compute bandwidths are sufficiently high. A speedup of up to 33 % is possible in the ideal case.
