PusOS: RISC-V Tabanlı Açık Kaynak Hafif Bir Sis Bilişim Sistemi Tasarımı

Öz

Sis bilişim, veriye yakın düğümlerde işlem yaparak düşük gecikme ve yüksek hizmet kalitesi sunmayı hedefleyen dağıtık bir bilişim modelidir. Bu çalışmada, yalnızca çekirdek modunda çalışan, RISC-V mimarisi üzerinde geliştirilen, nanokernel tabanlı ve açık kaynaklı bir işletim sistemi sunulmaktadır. Sistem, kaynak kısıtlı cihazlarda düşük gecikme, yüksek güvenilirlik ve küçük sistem ayak iziyle çalışacak şekilde tasarlanmıştır. Nanokernel mimarisi sayesinde bağlam değiştirme ve sistem çağrısı yükleri ortadan kaldırılarak uygulamalar doğrudan çekirdek alanında çalıştırılarak verimlilik artırılmıştır. Ağ, depolama, hesaplama, sanallaştırma ve yönetim işlevleri entegre edilerek QEMU sanal makine öykünücüsünde test edilmiştir. Linux ile yapılan karşılaştırmalı deneylerde, önerdiğimiz sisteminin veri toplama, depolama ve çoklu görevde 4–5,5 kat daha hızlı olduğu gösterilmiştir. Böylece sis bilişim alanı için güvenilir, genişletilebilir ve hafif bir alternatif işletim sistemi sunulmaktadır.

PusOS: Building an Open Source Lightweight Fog Computing System on RISC-V

Öz

Fog computing is a distributed computing model that aims to provide low latency and high quality of service by processing data near the source nodes. In this context, we present a nanokernel-based, open-source fog computing operating system developed on the RISC-V architecture that runs solely in kernel mode. The system is designed to operate with low latency, high reliability and a minimal footprint on resource-constrained devices. By using the nanokernel architecture, context switching and system call overheads are eliminated and applications run directly in kernel space to enhance efficiency. Integrated functionalities for networking, storage, computation, virtualization, and management have been tested extensively using the QEMU emulator. Comparative experiments with Linux demonstrate that the system performs 4 to 5.5 times faster in serial data collection, storage, and multitasking thereby providing a reliable, extensible and lightweight alternative OS for fog computing domain.
