About Me

I am a Research Staff Member (RSM) in the Cloud and Computing Infrastructure group at the IBM Research Lab, Zurich. Earlier in 2016, I graduated with a PhD from ETH, Zurich. 

My primary research areas are distributed systems, networking, operating systems, and storage. Broadly speaking, I am interested in the performance aspect of systems, spanning from multi-core CPUs to distributed environments. Currently I am investigating how to leverage high-performance network (e.g., 100+ Gbps network) and storage (10+ GBps, e.g., NVMe flash) devices in modern open-source analytics stacks such as Apache Spark, TensorFlow. Software artifacts from our group can be found at : https://github.com/zrlio

Occasionally, I put stuff on my technical blog that can be reached here: https://animeshtrivedi.github.io/blog/. My github profile is at https://github.com/animeshtrivedi.

News:

- August, 2018: Paper "Pocket: Ephemeral Storage for Serverless Analytics" is accepted at OSDI'18. 

- June, 2018: I will be presenting Crail at the DataWorks Summit in San Jose, CA [talk]. 

- April, 2018: Our work on a high-performance file format for big data systems (called "Albis") has been accepted at USENIX ATC'18. 

- November, 2017: Crail features in the FLOSS weekly podcast. Have a look here.
