Verification of Software Network Functions with No Verification Expertise

Arseniy Zaostrovnykh

Software network functions (NFs), such as a network address translator, load balancer, or proxy, promise to bring flexibility and rapid innovation to computer networks and to reduce operational costs. However, continuous updates and flexibility typically c ...

The IX Operating System: Combining Low Latency, High Throughput, and Efficiency in a Protected Dataplan

Edouard Bugnion, Christos Kozyrakis, Georgios Prekas, Mia Primorac, Ana Klimovic

The conventional wisdom is that aggressive networking requirements, such as high packet rates for small messages and μs-scale tail latency, are best addressed outside the kernel, in a user-level networking stack. We present ix, a dataplane operating system ...

IX: A Protected Dataplane Operating System for High Throughput and Low Latency

Edouard Bugnion, Christos Kozyrakis, Georgios Prekas, Ana Klimovic

The conventional wisdom is that aggressive networking requirements, such as high packet rates for small messages and microsecond-scale tail latency, are best addressed outside the kernel, in a user-level networking stack. We present IX, a dataplane operati ...

Enabling efficient OS paging for main-memory OLTP databases

Anastasia Ailamaki, Radu Ioan Stoica

Even though main memory is becoming large enough to fit most OLTP databases, it may not always be the best option. OLTP workloads typically exhibit skewed access patterns where some records are hot (frequently accessed) but many records are cold (infrequen ...

TwinDrivers: Semi-Automatic Derivation of Fast and Safe Hypervisor Network Drivers from Guest OS Drivers

Willy Zwaenepoel, Aravind Menon, Simon Schubert

In a virtualized environment, device drivers are often run inside a virtual machine (VM) rather than in the hypervisor. Doing so protects the hypervisor from bugs in the driver, and also allows the reuse of the device driver and its support infrastructure ...

Multi-Processor Operating System Emulation Framework with Thermal Feedback for Systems-on-Chip

Giovanni De Micheli, David Atienza Alonso, Luca Benini, Francisco Javier Rincon Vallejos, Pablo Garcia del Valle

Multi-Processor System-On-Chip (MPSoC) can provide the performance levels required by high-end embedded applications. However, they do so at the price of an increasing power density, which may lead to thermal runaway if coupled with low-cost packaging and ...

The host software for the real-time PHA X-ray diagnostic on TCV

Basil Duval

A real-time pulse height analysis (PHA) X-ray diagnostic for the TCV tokamak has been developed using CFN multi-DSP-based VME acquisition, processing and control board. The hardware is composed by: (i) a detection system based on a Si SDD detector; (ii) a ...

Unifying software and hardware of multithreaded reconfigurable applications within operating system processes

Miljan Vuletic

Novel reconfigurable System-on-Chip (SoC) devices offer combining software with application-specific hardware accelerators to speed up applications. However, by mixing user software and user hardware, principal programming abstractions and system-software ...
