EuroSys '19: Proceedings of the Fourteenth EuroSys Conference 2019Article No.: 20, Pages 1–16https://doi.org/10.1145/3302424.3303986We present a fast and scalable testing approach for datacenter/cloud systems such as Cassandra, Hadoop, Spark, and ZooKeeper. The uniqueness of our approach is in its ability to overcome the path/state-space explosion problem in testing workloads with ...

ACM Transactions on Storage (TOS), Volume 14, Issue 3Article No.: 23, Pages 1–26https://doi.org/10.1145/3242086Fail-slow hardware is an under-studied failure mode. We present a study of 114 reports of fail-slow hardware incidents, collected from large-scale cluster deployments in 14 institutions. We show that all hardware types such as disk, SSD, CPU, memory, ...

Rivulet: a fault-tolerant platform for smart-home applications
Middleware '17: Proceedings of the 18th ACM/IFIP/USENIX Middleware ConferencePages 41–54https://doi.org/10.1145/3135974.3135988Rivulet is a fault-tolerant distributed platform for running smart-home applications; it can tolerate failures typical for a home environment (e.g., link losses, network partitions, sensor failures, and device crashes). In contrast to existing cloud-...

SoCC '17: Proceedings of the 2017 Symposium on Cloud ComputingPages 295–308https://doi.org/10.1145/3127479.3131622We reveal loopholes of Speculative Execution (SE) implementations under a unique fault model: node-level network throughput degradation. This problem appears in many data-parallel frameworks such as Hadoop MapReduce and Spark. To address this, we ...

Scalability bugs are latent bugs that are cluster-scale dependent, whose symptoms typically surface in large-scale deployments, but not ...
