A Checklist Manifesto for Empirical Evaluation: A Preemptive Strike Against a Replication Crisis in Computer Science
In 2009, Dr. Atul Gawande, a surgeon at Brigham and Women’s Hospital in Boston, published The Checklist Manifesto: How to Get Things Right, describing his experience using checklists to reduce the risk of errors. Gawande observed that a number of serious...
Early Measurements of Intel’s 3DXPoint Persistent Memory DIMMs
Editors Note: This is the second of two independent posts on the performance of Intel’s new memory technology. For the last ten years, researchers have been anticipating the arrival of commercially available, scalable non-volatile main memory (NVMM) technologies...
Using Intel Optane DC Persistent Memory for In-memory Graph Analytics
Intel Optane DC persistent memory modules are like DRAM in form factor and can be configured as volatile main memory, persistent memory or as a combination.
Tackling the Pipeline Problem in the Architecture Research Community
Computer architecture is an important and exciting field of computer science, which enables many other fields (eg. big-data processing, machine learning, quantum computing, and so on). For those of us who pursued computer architecture as a career, this is well...
Three Other Models of Computer System Performance: Part 2
With two blog posts, we argue for more use of simple models beyond Amdahl’s Law. Part 1 previously discussed Bottleneck Analysis and Little’s Law, while this post (Part 2) presents the M/M/1 Queue.
HPCA-25 Summary
HPCA celebrated its 25th anniversary this year with significant participation of over 300 attendees! It was held in Washington D.C., USA between February 16-20. Accelerators was a bigger theme this year (not only for ML but covering a broader range of domains...
Three Other Models of Computer System Performance: Part 1
With two blog posts, we argue for more use of simple models beyond Amdahl’s Law. This Part 1 discusses Bottleneck Analysis and Little’s Law, while Part 2 presents the M/M/1 Queue. Computer systems, from the Internet-of-Things devices to datacenters, are complex and...
Tips for a New Computer Architecture PhD Student
I have been fortunate enough to have many helpful senior students and two wonderful advisors to learn from throughout my PhD. Now as a senior PhD student myself, I have identified some lessons that proved most valuable as well as common mistakes made by younger...
The Role of Luck in Academic Careers
Modern academic culture is founded on perpetual evaluation and relentless ranking of researchers and their results. Obtaining competitive research funds and publishing in top-tier venues are prerequisites to a successful career. Unfortunately, as was shown by several...Subscribe
