Technical Projects

Performance Prediction Toolkit (PPT)

Python, Simian Parallel Simulator

Parallel application and system performance prediction toolkit implemented on Simian parallel discrete-event simulator. PPT is a collaborative project with Los Alamos National Laboratory (LANL), NM. It models large parallel interconnections such as Torus, Fat-tree, DragonFly, InfiniBand and provides easily extensible modeling constructs. PPT also includes fairly detailed processor, memory-cache, GPU-accelerator models that an application model can make use of, for making accurate predictions.

May 2015 - April 2018


Python, C, Java, Cuda, Cetus, OpenARC

HPC Simulation model construction using static program analysis. A number of advanced program analysis techniques has been used to identify program performance.

May 2015 - July 2015

Distributed Data-Center Real-time Simulator

C, C++, PRIME, Libpcap, Linux, OVS, Containers

Distributed Simulator (2016) Efficient distributed hybrid real-time cloud, data-center, and large network simulator . The real-time simulator PRIME which was using a single core in linux is capable of processing 300,000 events/second. The simulator makes full use of the event rate of the PRIME real-time simulator. This particular implementation achieved 5x throughput increase compared to all previous parallel real-time simulation implementation.

January 2016 - December 2016

HPC Workload Simulator

Python, HPC Workload

I developed a simulator designed specifically for evaluating job scheduling algorithms on large-scale HPC systems. It allows large-scale HPC cluster workload modeling with job scheduling, task mapping and application execution. The simulator can evaluate different job scheduling and task mapping algorithms on the specific target HPC platforms more accurately. This allows prediction and measurement of application performance variability in different runtime conditions. Github:

Linux, OVS, Containers, Network namespaces, Shell, Pox, ip, veth

Network emulation using Linux namespaces, OVS w/ Pox Controller. A cloud infrastructure or data-center network is programmed as a graph or tree in python. Large models can also be built by supplying parameters. Alternatively, the network topology can be read from a file. The network can be deployed as containers with links. Consider connecting Docker / LXC / Linux Namespaces with virtual ip-links/veth-pairs. To enable software defined networking SDNScaleNet uses Open vSwitch(OVS) and pox-controller.

January 2016 - December 2016

PrimoGENI Constellation

C++, Java, Shell, Apache-mina - state message transfer), Jsch - port forwarding, Perl, LXC, InstaGENI, ExoGENI, VM instances.

Developed distributed hybrid network experimentation framework on NSF GENI testbed. Simulated, emulated and real-time networking devices communicates in real-time parallel simulation.

January 2016 - December 2016

Trading Bot

Python, Python-stockstats, CCXT, QuantConnect.

Cryptocurrency trader using financial indicators. The algorithm was successfully deployed on Coinbase/GDAX exchange. The trader used Python-pandas to handle data structures and python-stockstats to calculate the indicators which a trader can mix and match to find the signals. We used CCXT library to make the API calls, which makes the program independent of the exchange and their API. We also built an early prototype on QuantConnet platform which provided excellent back-testing capability.

January 2018 - March 2018

Arbitrator Bot -- Cryptocurrency

Python, Python-binance, API.

A cryptocurrency arbitrator that exploits ask/bid price differences in different market (order depths). For example, if there exists an arbitration BTC/LTC and ETH/LTC markets or the orders, the trader finds the arbitration for all such coin pairs against the base pairs. Few milliseconds, prototype arbitration processing time achieved for hundreds of markets on cryptocurrency exchange Binance.

January 2018 - April 2018

Apart from being a researcher, I like to code and prototype my ideas in Python. I like to read about disruptive ideas and enjoy reading about investment specially public company stocks in US. If someone is building something amazing like how/where Amazon is encrypting the data for AWS/S3, I am intrigued to know more and discuss in-depth.

In terms of physical activity, I like to visit places, hike natural trails, climb to the top of mountains and sprint on the tracks. At times, Katana sword fights amazes me. During my free days, I like getting closer to nature, mountains, and exploring outdoors.

To entertain and keep my brain active, I enjoy playing computer games more specifically, League of Legends. My favorite role is jungler then fill who loves hunting with Nocturne, Xin Zhao. Binge watching a sci-fi? Share your thoughts, I might like it as well.
