Reducing Embodied Carbon is Important
A recent post raises awareness of the challenges of reducing operational carbon, while also controversially challenging the importance of embodied carbon. We rebut the arguments raised against using embodied carbon as a design metric and conclude by advocating for more research on reducing embodied carbon.
Emerging Fault Modes: Challenges and Research Opportunities
Overview Reliability is essential for computing. However, as technology nodes have scaled, there have been several fundamental physical challenges to overcome to provide the abstraction of reliability. One such challenge has been the emergence of marginal...
Current status, needs, and challenges in Heterogeneous and Composable Memory from the HCM workshop (HPCA’23)
Introduction Memory systems are evolving into heterogeneous and composable architectures. Heterogeneous and Composable Memory (HCM) offers a feasible solution for terabyte- or petabyte-scale systems, addressing the performance and efficiency demands of emerging...Fast memcpy, A System Design
When I worked at Google, fleet-wide profiling revealed that 25-35% of all CPU time was spent just moving bytes around: memcpy, strcmp, copying between user and kernel buffers in network and disk I/O, hidden copy-on-write in soft page faults, checksumming, compressing,...Subscribe
