Journal ArticleDOI
The gem5 simulator
Nathan Binkert,Bradford M. Beckmann,Gabriel Black,Steven K. Reinhardt,Ali G. Saidi,Arkaprava Basu,Joel Hestness,Derek R. Hower,Tushar Krishna,Somayeh Sardashti,Rathijit Sen,Korey Sewell,Muhammad Shoaib,Nilay Vaish,Mark D. Hill,Darien Wood +15 more
TL;DR: The high level of collaboration on the gem5 project, combined with the previous success of the component parts and a liberal BSD-like license, make gem5 a valuable full-system simulation tool.
Journal ArticleDOI
Multifacet's general execution-driven multiprocessor simulator (GEMS) toolset
Milo M. K. Martin,Daniel J. Sorin,Bradford M. Beckmann,Michael R. Marty,Min Xu,Alaa R. Alameldeen,Kevin E. Moore,Mark D. Hill,Darien Wood +8 more
TL;DR: The Wisconsin Multifacet Project has created a simulation toolset to characterize and evaluate the performance of multiprocessor hardware systems commonly used as database and web servers as mentioned in this paper, which includes a set of timing simulator modules for modeling the timing of the memory system and microprocessors.
Proceedings ArticleDOI
Managing Wire Delay in Large Chip-Multiprocessor Caches
Bradford M. Beckmann,Darien Wood +1 more
TL;DR: This paper develops L2 cache designs for CMPs that incorporate block migration, stride-based prefetching between L1 and L2 caches, and presents a hybrid design-combining all three techniques-that improves performance by an additional 2% to 19% overPrefetching alone.
Proceedings ArticleDOI
Heterogeneous system coherence for integrated CPU-GPU systems
Jason Power,Arkaprava Basu,Junli Gu,Sooraj Puthoor,Bradford M. Beckmann,Mark D. Hill,Steven K. Reinhardt,Darien Wood +7 more
TL;DR: This paper develops Heterogeneous System Coherence (HSC) for CPU-GPU systems to mitigate the coherence bandwidth effects of GPU memory requests, which replaces a standard directory with a region directory and adds a region buffer to the L2 cache.
Proceedings ArticleDOI
Heterogeneous-race-free memory models
Derek R. Hower,Blake A. Hechtman,Bradford M. Beckmann,Benedict R. Gaster,Mark D. Hill,Steven K. Reinhardt,Darien Wood +6 more
TL;DR: A new class of memory consistency models that add scoped synchronization to data-race-free models like those of C++ and Java, and quanti-tatively shows that HRF-indirect encourages forward-looking programs with irregular parallelism by showing up to a 10% performance increase in a task runtime for GPUs.
