Connecting SLICES-RI and Chameleon

An Approach towards Portable, Reproducible Experiments

"Connecting SLICES-RI and Chameleon: An Approach towards Portable, Reproducible Experiments" explores the creation of replicable scientific experiments through 'pos', a novel tool and methodology. Integrated with Chameleon and other public research infrastructure, 'pos' allows researchers to replicate experiments reliably across shared infrastructures. This collaboration aligns with the SLICES-RI initiative to enhance research portability. Authors Henning Stubbe, Sebastian Gallenmüller, and Georg Carle also share insights into maintaining adaptability and variety in long-term research projects, crucial for advancing experimental reproducibility and collaboration.

CHI@Edge: Transitioning from Successful Preview to Full Production

Unlock the power of edge computing with CHI@Edge - In production now!

In 2021, we introduced CHI@Edge, a cutting-edge testbed tailored to the dynamic needs of edge computing and IoT research. Our initial offerings included a robust selection of devices like Raspberry Pi 4s, Nvidia Jetson Nanos, and Jetson Xaviers, tailored for high-performance yet low-power edge computing tasks. Today, we're thrilled to announce the transition of CHI@Edge from a widely embraced preview to its official full production phase.

Community Workshop on Practical Reproducibility - Monday, November 18, 2024 - Atlanta GA

As the digital age accelerates, the importance of reproducibility in computational science has never been more critical. This year, we are thrilled to announce a workshop focusing on the theme of "Practical Reproducibility" in Computer Science. Scheduled for November 18, 2024, at Terminus 330 in Atlanta, this full-day workshop promises to be a milestone event in advancing the science of reproducibility.

Chameleon Changelog for March 2024

This month, we are very excited to announce CHI@Edge is coming out of preview! We also have new artifacts that allow you to explore Fabnet with, and new per-user SU budgeting.

Baleen: ML Admission & Prefetching for Flash Caches

Future-Proofing Data Storage: The Role of ML in Smart Caching Solutions

In the era of exponential data growth, the "Baleen" project introduces a groundbreaking approach to flash caching, utilizing machine learning to optimize data storage. This method intelligently decides what to store and prefetch, significantly reducing the hardware required, lowering costs, and enhancing sustainability. This blog explores the challenges of managing vast data volumes and how "Baleen" offers a novel solution, poised to revolutionize data center operations and sustainability practices.

Understanding the New FABRIC Layer 3 Connection

Multi-site experiments with FABRIC: Sometimes Layer 3 is all you need

Discover how Chameleon's testbed capabilities have been enhanced with the introduction of the FABRIC Layer 3 connection in our new blog post. Learn about the powerful and flexible networking options it offers, how it simplifies the process of routing to FABRIC resources, and how it enables low-latency and high-bandwidth traffic routing between CHI@UC and CHI@TACC.

Chameleon Changelog for February 2024

This month, we have a packed changelog, we have a lot of exciting updates with FABRIC connectivity, and we’ve added a second interface to nodes on CHI@UC that did not have one. Additionally, for Edge users, we have improvements to interacting with containers and using Jetson Nano GPUs. Lastly, there are updates to our lease stacking policies.

Metis Unleashed: A New Dawn for File System Integrity

File systems are a fundamental part of computer systems, which organize and protect the files and data on assorted devices, including computers, smartphones, and enterprise servers. Due to its crucial role, vulnerabilities and bugs in the file system can lead to severe consequences such as data loss and system crashes. After decades of development, file systems have become increasingly complex, yet bugs continue to emerge. Meanwhile, many new file systems are invented to support new hardware or features, often without undergoing comprehensive testing. To address these gaps, we develop a checking framework (Metis) that can thoroughly and efficiently test file …
