About Me

I am a Ph.D. student at the IT University of Copenhagen, Denmark. My research focus is on Resource-Aware Data Systems, developing mechanisms for improving the utilization and efficiency of the underlying hardware infrastructures.

I obtained a Master's degree in Computer Architecture from the Sharif University of Technology, Tehran, Iran. During my Master's, I conducted extensive research on designing and implementing an energy efficient design for on-chip memories of GPUs, which resulted in two submissions.

My primary field of interest is Computer Architecture, particularly GPUs, parallel computing systems, energy-efficient designs, and heterogeneous systems. Also, I am perfectly eager to contribute to work on hardware accelerators, especially for Machine Learning and Deep Learning applications.

November 2021 - Present

Doctor of Philosophy (Ph.D.)

Currently, I am a Ph.D. student working on Resource-Aware Data Systems under Prof. Pınar Tözün's supervison.

The focus is on developing mechanisms for higher utilization and efficiency of underlying hardware infrastructures for Data-Science, especially for Deep Learning applications.

Sharif University of Technology

Tehran, Iran

September 2016 - September 2018

Masters of Sciences (M.Sc.)

Working under supervision of Prof. Hamid Sarbazi-Azad. The focus of my research has been to introduce an energy efficeint on-chip memories design with negligible performance overhead for GPUs. I proposed and implemented an Unified on-chip memory for shared and global accesses that increases on-chip resources utilization by on-chip resources dynamic management. I implemented and analyzed proposed designs using simulators such as GPGPU-Sim, and self-written C and Python codes. This work resulted in two consecutive submissions. Also, I contributed to another work on developing a mechanism for providing higher utilization of GPUs on-chip resources.

Working under Prof. Pınar Tözün's supervison in Data-Intensive Systems and Applications (DASYA) research team.

I work on designing and developing mechanisms for higher utilization and efficiency of commodity hardware (CPU-GPU) for Data-Sciene applications, especially Deep Learning applications.

Sharif University of Technology

September 2016 - August 2019 | September 2020 - February 2021

Working under Prof. Hamid Sarbazi-Azad's supervision in High-Performance Computing Architectures & Networks (HPCAN) research team.

I worked on an energy efficeint on-chip memory design with negligible performance overhead for GPUs. The proposed and implemented mechanism was an Unified on-chip memory for shared and global accesses that increases on-chip resources utilization by on-chip resources dynamic management. I implemented and analyzed proposed designs using simulators such as GPGPU-Sim, and self-written C++ and Python codes. For studying the behavior of shared memory accesses, generated address by the simulator traced and fed to the self-written C++ and Python codes. Then, based on the observations, the source code of the GPGPU-Sim simulator manipulated to reflect the proposed architecture. This work resulted in two consecutive submissions. Also, I contributed to another work on developing a mechanism for providing higher utilization of GPUs on-chip resources.

Projects

⬗ Unified On-chip Memory for Shared and L1 Cache Accesses for GPUs

– For my master's thesis, I implemented a unified on-chip memory to serve both the shared memory and level one data cache accesses. I logged the addresses generated by the GPGPUSim simulator, and then I fed them to my self-written Python script to study their locality, liveness, and read-after-write frequency charactersitics. Then, based on the observations, the proposed mechanism was implemented by manipulating the GPGPU-Sim simulator.

⬗ Cache with different Configs

– I implemented direct-mapped and set-associative cache for my advanced computer architecture course. Then, I did experiments on it to observe the effects of different policies on hit/ miss rate. It is accessible on my Github page with this link.

⬗ Morris Mano's Basic Computer

– During my bachelor's computer architecture course, I designed and implemented a basic computer (called Mano's basic computer) in the Quartus II Schematics. Then when I was doing my master's, and I was a computer architecture course's TA, I implemented this basic computer in Verilog HDL with more details once more, the GitHub link.

⬗ Python Basics, Data Structures and Algorithms, Parallel Programming with GPUs etc. Tutorials on Github

– In my free time,I work on preparing tutorials for those who want to learn fast and easily. You can check them out on my GitHub page.

⬗ Web Development Projects

– I worked as a back-end developer in several web development teams. I was preparing queries to the databases to get out the wanted data for the designed forms by the front-end team. Additionally, I was responsible for providing APIs to send the needed data to the mobile programmers. Also, I contributed to a URL Shortener on GitHub. I developed an API in Go programming language to ease the job of people who want to write API endpoints in Go, and they don't know how and where to start.

⬗ Design and Implementation of An Efficient Archiving System and some other automation systems in MS

– During my conscription, I designed, implemented, and organized an efficient archiving system in Excel with VBA regarding the documents type and their transactions. Before my system, most of the work was done manually, by automizing the processes, the working crew had more free time.
