“…The network stack is a crucial OS service, and its reliability has been the subject of multiple studies based on microkernels/multiserver OSes using state replication [12], partitioning [35], and checkpointing [21]. Several user-space network stacks such as mTCP [40], MegaPipe [25], and OpenOnload [65] have been designed to bypass the OS and avoid various related overheads.…”

network components fail or need to be upgraded. Finally, to e ciently use hardware resources, applications can dynamically switch between the indirect and direct modes based on their I/O load at run-time. We evaluate LibrettOS with 10GbE and NVMe using Nginx, NFS, memcached, Redis, and other applications. LibrettOS's performance typically exceeds that of NetBSD, especially when using direct access.

“…The presented model is applied to the uplink transmission in the single-carrier WiMAX system as a multi-class priority TDMA queueing system in order to analyse the average packet delays of different service classes. The authors of [34] demonstrated that a processor's fast cores may not be ideal for system workloads and that less can be more in some situations. Furthermore, in [35], a novel fuzzy testing technique, HFuzz, was proposed as a solution enabling efficient testing on real heterogeneous architectures.…”

The present paper considers a model of stalling in a queueing system (QS) with any number of different capacities of heterogeneous servers. The state graph and the corresponding linear system for steady-state probabilities are derived using the standard Markov chain technique. The obtained solution of the steady-state probabilities model is numerically stable; the complexity of the corresponding expressions does not depend on the number of QS states; thus, they enable us to analytically study the QS characteristics. Optimization of a stalling buffer is considered as well, and it is shown that stalling helps us to solve the slow server problem under an appropriate choice of stalling buffer size, making the slow servers usable under various values of system load. The asymptotic conditions of optimal query distribution in channels, when the ratio of the capacities of the fast and slow servers is increasing, are also established. Moreover, some applications of the developed model in heterogeneous server clusters and in work productivity modelling for forest harvesting applications are discussed.
