Tenant-level network performance isolation in Flowtune
Performance isolation is a major concern for multi-tenant datacenters. Many service level agreements include a specification on the allotment of resources. For tenants, these resource guarantees are critical to the availability and efficiency of their services. While CPU, disk, and memory isolation …

Evaluating SigmaOS with Kubernetes for Orchestrating Microservice and Serverless Applications
… procs to achieve high resource utilization and performance isolation. This thesis compares SigmaOS with Kubernetes, a mainstream cloud operating system, using a microservice-style social network website and a serverless image resizing program. It measures their performances on a small-scale …

Operating system level resource management for real-time systems
… critical in providing required real-time performance. Management of concurrently shared hardware resources---such as shared caches, DRAM controllers, DRAM modules, hardware prefetchers---is important because contention in the shared resources can significantly degrade applications' …

Reducing deadline miss rate for grid workloads running in virtual machines: a deadline-aware and adaptive approach
… of the virtualization overhead on HPC grid job’s performance, and optimization of job execution times to increase their throughput by reducing job deadline miss rate. Integration of the virtualization into the grid to deploy on-demand virtual machines for jobs in a way that is transparent to the …

A SIMD architecture for hard real-time systems
Emerging safety-critical systems require high-performance data-parallel architectures and, problematically, ones that can guarantee tight and safe worst-case execution times. Given the complexity of existing architectures like GPUs, it is unlikely that sufficiently accurate models and algorithms …

Dependability where the mobile world meets the enterprise world
… suffers from the problem of imperfect performance isolation where contention for low-level hardware resources can impact application performance. Through a set of rigorous experiments in a private cloud testbed and in <em>EC</em><sup>2</sup>, we show that interference induced …

Application Interference in Multi-Core Architectures: Analysis and Effects
… electricity bills while maintaining reasonable performance isolation. The last one is of our particular interest. Most cloud systems are accounted and billed not by useful throughput, but by resource usage. For example, a cloud provider may charge according to cumulative CPU time and/or average …

Next-generation safety-critical systems on multi-core platforms
… on multi-core systems. While predictability and performance determinism are of paramount importance in safety-critical applications, cost containment and time-to-market are dominant factors for the large-scale adoption of novel technologies. Hence, our work proposes solutions that can be adopted …

A hardware and software architecture for efficient datacenters
… are architected to maximize long-term, average performance (e.g., throughput over a period of seconds), and cannot provide the short-term performance guarantees needed by these applications. The stringent performance requirements of latency-critical applications make power management …
