Implementing Secure Shared Memory for Side-Channel-Resistant Enclaves
… more critical than ever for remote users to get strong security guarantees to secure sensitive computation they run on untrusted machines. Enclaves or Trusted Execution Environments (TEEs) are a powerful trusted computing primitive that can address this problem; through carefully co-designed …

Replication of Concurrent Applications in a Shared Memory Multikernel
… replication approaches do not provide strong isolation among the replicas, which allows the faults to be propagated from one replica to another. In order to provide an intra-machine replication technique with strong isolation, in this thesis we present a SMR system on a multi-kernel OS. …

Enhancing HPC on Virtual Systems in Clouds through Optimizing Virtual Overlay Networks
… distributed and parallel computing systems with strong isolation, portability, and recoverability properties. However, in extremely high throughput and low latency networks, such overlays can suffer from bandwidth and latency limitations, which is of particular concern in HPC environments. …

Interposing the Syscall Boundary: Transparent Python Execution in SigmaOS
… support to cloud applications while maintaining strong isolation, security, and efficient startup times and scheduling among multiple users. While σOS and its container startup times have been successfully benchmarked for tasks written, compiled, and statically linked in Golang and Rust, it …

Lightweight and purpose built hypervisor for malware analysis
… a compelling platform for malware analysis, with strong isolation and the ability to save and restore guest state. Commodity virtual machine monitors (VMMs), however, are not designed for malware analysis. Due to their complexity, they often fail to provide transparency and even expose …

Improving Operating System Security, Reliability, and Performance through Intra-Unikernel Isolation, Asynchronous Out-of-kernel IPC, and Advanced System Servers
… OSs improve security and reliability through isolation, but they come at a performance cost due to crossing privilege layers through IPCs, system calls, and mode switches. Library OSs, on the other hand, implement kernel components as libraries which avoids crossing privilege layers in …

Increasing Compliance of Personal Protective Equipment S election and Use for Isolation Precautions Among RNs & NAs on a Med-Surg Unit
<p><strong>Background:</strong> Due to the high potential of transferring infectious diseases and/or organisms among patients, themselves, and the community, healthcare workers (HCWs) must be knowledgeable and confident in selecting the appropriate type of personal protective equipment (PPE), and …

Next Generation Operating Systems for the Datacenter
… extensive application rewrites, and provide weak isolation, making them unsuitable for general-purpose, shared environments. This thesis presents a new datacenter operating system, composed of three integrated systems: Shenango, Caladan, and Junction. Together, they preserve the high-performance, …

Towards secure web browsing
… layer of software and make it simple; 2) enforce strong isolation between distinct browser-level components; 3) employ simple and explicit communication between components; 4) provide the right set of operating system abstractions; 5) maintain compatibility with current browser standards; 6) …

Population structure and the molecular genetics of petal spot pigmentation in Gorteria diffusa
… by locality. The genetic analysis indicated strong isolation by distance patterns, hypothesised to be due to limited seed dispersal. These findings suggest that limited dispersal may be a key component contributing toward the evolution of G. diffusa floral morphotypes, pending further …

An effect system and language for deterministic-by-default parallel programming
… by default. A transactional runtime provides isolation for atomic statements, while the extended effect system provides stronger compile-time safety guarantees than any system we know of. In addition to determinism by default, the language guarantees race freedom; strong isolation for atomic …
