Using the splitkernel model, we built LegoOS, a new OS designed for hardware resource disaggregation. Avaya Cloud Office. Introduction Disaggregated architectures have received intense and widespread attention by both industry (e.g, HP (7; 11), Intel (3), Huawei (2), analysis of software related I/O bottlenecks in data processing workloads can be found in [26]. Rethinking Software Runtimes for Disaggregated Memory Abstract Disaggregated memory can address resource provisioning inefficiencies in current datacenters. LegoOS appears to users as a set of distributed servers. 2020. The latest work in memory disaggregation [] demonstrated the feasibility of remote memory by implementing a prototype using a swap device to emulate remote memory, and also evaluated the performance of Spark [] and COST [] in a disaggregated datacenter environment. [43] The hardware community has suddenly gone wild over a new idea they call "disaggregated" cloud computing infrastructures. Compute Orchestration Gen 2: Static Allocation, Heterogeneous Hardware. Research includes applications and infrastructure for AI and machine learning, hardware acceleration, operating systems, networking, security, storage and data management - all in the context of distributed systems. . Using this observation, we implemented a new software runtime for disaggregated memory that improves average memory access time by 1.7-5X and reduces dirty data amplification by 2-10X, compared to state-of-the-art systems. Disaggregation is a term used to describe an approach for organizing and accessing a cluster of compute resources in which instead of providing applications only local node resources, each .

Software engineer intern in the Platforms Networking team (summer 2010, Mountain View, CA) and Mobile Gateway team (summer 2007, Munich . Instead of having server units with "converged" compute, memory, and storage resources, a disaggregated data center (DDC) has pools of resources of each type connected via a network. Our solution is to "disaggregate" monolithic servers into distributed, network-attached hardware components that can each manage its own resource and can fail independently. . a runtime platform for composing and coordinating distributed tracking applications. Our main observation is that we can use cache coherence instead of virtual memory for tracking applications' memory accesses transparently, at cache-line granularity. They have this follow up work "Rethinking software runtimes for disaggregated memory, ASPLOS'21". The real FPGA has not been built yet. enabling cache-line granularity dirty data tracking and eviction. Rethinking Software Runtimes for Disaggregat.
