Tokenomics: Quantifying Where Tokens Are Used in Agentic Software Engineering

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
LLM-based Multi-Agent (LLM-MA) systems are increasingly applied to automate complex software engineering tasks such as requirements engineering, code generation, and testing. However, their operational efficiency and resource consumption remain poorly understood, hindering practical adoption due to unpredictable costs and environmental impact. To address this, we conduct an analysis of token ...

Moving beyond fork() + exec()

A recent Linux kernel proposal to add "spawn templates" to optimize the fork() and exec() pattern has been rejected, but it may point to a new process-creation primitive in the future. The discussion highlights the need for a better process-creation mechanism, with some suggesting a native implementation of posix_spawn() and others proposing alternative approaches using existing system calls.
