We are a group of distributed systems researchers in the Department of Computer Science at Cornell University, united in the belief that a deeper understanding of the theoretical framework that shapes the design space is essential to building systems that surpass the performance, scalability, and robustness of the state of the art; and, conversely, that the problems that arise when addressing systems’ “pain points” can serve as a compass to guide us to exciting new theory.
We are not afraid to pursue a problem wherever it will lead us—we build systems and prove theorems with equal gusto and flair. Over the years, we have been exploring problems in message logging, scalable web caching, state machine replication, quorum systems, Byzantine fault-tolerance, and Game Theory. We are currently intrigued by the many facets of the apparent tension between ease of programming and performance in distributed systems and databases: by gaining a deeper understand it of it, our aim is to recognize to what degree this tension is fundamental and, when it is not, develop novel ways to resolve it (see Research).
Cornell is one of the intellectual cradles of distributed computing and a special place that embraces researchers who, like us, are attracted by a research style that bridges artificial area divisions in the pursuit of scholarship. We are fortunate to have such travel companions within Cornell’s broader systems group and beyond.
We are grateful for funding from the National Science Foundation as well as awards and gifts from Google, Huawei, Facebook and Amazon.
This has been a banner year for our group at SOSP: we contributed to three papers! It looks like we really earned all that ice cream...
Florian joined forces with Matt and Yunhao (not to mention Lorenzo and Natacha, now at Berkeley) to produce 'Basil: Breaking up BFT with ACID (transactions)';
Sowmya and Matt were first joint authors in a collaboration with researchers at MSR that produced 'PRISM: Rethinking the RDMA Interface for Distributed Systems';
and Matt (he again!) co-authored 'Regular Sequential Serializability and Regular Sequential Consistency' with friends at Princeton.
Nothing like a ridiculous amount of Cornell ice cream after an SOSP push. And it is nice to finally be together!Apr 27, 2021
