VM Matters: A Comparison of WASM VMs and EVMs in the Performance of Blockchain Smart Contracts
Beyond an emerging popular web applications runtime supported in almost all commodity browsers, WebAssembly (WASM) is further regarded to be the next-generation execution environment for blockchain-based applications. Indeed, many popular blockchain ...
A Product-form Network for Systems with Job Stealing Policies
In queueing networks, product-form solutions are of fundamental importance to efficiently compute performance metrics in complex models of computer systems. The product-form property entails that the steady-state probabilities of the joint stochastic ...
Queuing Network Models of Multiservice RANs
In this article, we present a new queuing network model for the analysis of a portion of a radio access network (RAN) comprising macro cell base stations (BSs) and small cell BSs offering “streaming” and “elastic” services. Streaming services require a ...
Load Balancing with Job-Size Testing: Performance Improvement or Degradation?
In the context of decision making under explorable uncertainty, scheduling with testing is a powerful technique used in the management of computer systems to improve performance via better job-dispatching decisions. Upon job arrival, a scheduler may run ...
