Dear SAFARI friends,

2019 and the first three months of 2020 have been very positive eventful times for SAFARI. We have welcomed new students, interns, postdocs, and visitors from all over the world. We have also said goodbye to several group members who have graduated; some who have returned to their studies and academic positions elsewhere, and some who have moved on to new positions in industry and academia. We were honored and humbled with several research and technical impact awards. We presented and published new research on computer architecture, memory systems, hardware security, bioinformatics and beyond at top venues like ISCA, MICRO, ASPLOS, HPCA, SIGMETRICS, IEEE S&P, DSN, PLDI, DAC, and Bioinformatics. We have also written various invited articles on various topics for journals and books. We started new research projects and collaborations with industry partners, as well as with other research institutions. We delivered many lectures, courses, and talks at many venues and institutions around the world; we have shared all materials publicly as much as possible, including all the lecture materials as well as the research artifacts we develop.

In this inaugural edition of our SAFARI newsletter, we would like to share some of our group highlights from the past 15 months with you to reflect on our accomplishments and fruitful collaborations, and look ahead to new and inspiring research projects, collaborations, and educational activities in 2020. We hope it is useful and informative, and welcome any feedback and new ideas, as always.

Stay safe and healthy, and keep in touch.

Enhancing Programmability, Portability, and Performance with Rich Cross-Layer Abstractions

Nandita Vijaykumar

Carnegie Mellon University, ECE
PhD Defense — October 11, 2019
Programmability, performance portability, and resource efficiency have emerged as critical challenges in harnessing complex and diverse architectures today to obtain high performance and energy efficiency. While there is abundant research, and thus significant improvements, at different levels of the stack that address these very challenges, in this thesis, we observe that we are fundamentally limited by the interfaces and abstractions between the application and the underlying system/hardware—specifically, the hardware-software interface.

Machine Learning Systems for Highly-Distributed and Rapidly-Growing Data

Kevin Hsieh

Carnegie Mellon University, ECE
PhD Defense — September 5, 2019
The usability and practicality of any machine learning (ML) applications are largely influenced by two critical but hard-to-attain factors: low latency and low cost. Unfortunately, achieving low latency and low cost is very challenging when ML depends on real-world data that are highly distributed and rapidly growing (e.g., data collected by mobile phones and video cameras all over the world). Such real-world data pose many challenges in communication and computation. For example, when training data are distributed across data centers that span multiple continents, communication among data centers can easily overwhelm the limited wide-area network bandwidth, leading to prohibitively high latency and high cost.

How to Build an Impactful Research Group

Onur was invited to give a talk during the Design Automation Conference Early Career Workshop, in Las Vegas, June 2019. He answered several questions on "How to Build an Impactful Research Group":

Q1: What are the best practices that you would suggest to your peers as being essential for the success of an academic team?

Onur: There is no single way of having impact. The critical thing is finding the way that works well for you and your goals, that you can own, cherish and optimize. Find the methods that work for you.
Start out with the right motivation and mindset: Mindset 1: change the world positively, have high influence; Mindset 2: enable students to achieve a potential that they did not even think they could ever achieve. Motivation correction may be needed at times – be ready.

Get motivated students, build a team of excellence
Focus on Learning and Scholarship:
Learning by example, learning by doing, learning by open, critical discussion
Focus on insight, encourage new ideas
Set the bar high
Choose Great Problems and guide your group toward them (but give them freedom)
Emphasize clarity and rigor in communication (critical for high impact)
Foster collaboration within group, across groups, with companies
Inspire and reach out, be resilient, follow your passion,
Build infrastructure to enable your passion (Big Projects)

Q2: How important is the heterogeneity of the group?

Onur: Diversity is very important, no two people are the same -- everyone brings perspective. It is critical to be diverse, accepting, and inclusive, e.g. age, gender, experience level, education level, geography (natural in our field).

Create an environment that values
free exploration, openness, collaboration, hard work, creativity

Q3: What are the main characteristics and skills one should take into account when choosing PhD students and researchers for new and impactful research groups?

Onur: Motivation and Mindset; Creativity; Resilience; Hard work; Boldness; Perseverance, commitment; Intellectual strength; Openness to feedback; Communicativeness

Our group is very heterogenous and diverse. This encourages creative diversity and helps to generate new and different ideas. We embrace diversity and team collaboration, and regularly host interns from all over the world. If you are interested in working with SAFARI, apply to work with us!

Meet our members: on research and career

Nandita Vijaykumar defended her PhD in October, and will start a position as Assistant Professor at the University of Toronto in 2020.

Q1:
What are the main things you learned during your PhD on how to do great research, write well, and publish strong papers
?
nandita
Selecting topics well is very important. Half the battle is won by choosing the right problems to work on and by asking the right questions. This is unfortunately a slightly esoteric art that only comes with experience, continuously learning from other people, and persistence. An easy way to avoid pitfalls here is to always get *early* feedback on your work.

Write for your readers not for yourself. This has many aspects: using simple and very concise language; structured writing (SAFARI has great guidelines for this); articulating contributions well and up front; avoiding red herrings; and focusing on what you want to convey to the reader.

Persistence, persistence, persistence. Regardless of how good the idea is or how interesting the problem is, publishing a great paper requires tremendous hard work and persistence. This includes many late nights, dealing with failures, improving your work by taking criticism constructively, and relentless optimism.

Q2: What are the main tips you could give for a successful job search?

My thoughts here are focused on an academic or research-oriented job search. Some tips:

Preparation is key: It is absolutely critical to position your research contributions well and to be able to articulate it very effectively in different settings -- whether a 1 minute elevator pitch, 30 minute 1:1 discussion, a job talk, or a research statement. Doing this requires a *lot* of practice and getting feedback from different people. It helps tremendously to position and establish yourself as a leader/expert in some small and important sub-area within the broader field. Similarly, it is important to position and articulate future research directions well.

Networking and connecting with people
: I cannot stress the importance of this, not only in an academic job search but also in industry (more so for jobs higher up the ladder). It is tremendously helpful to use every opportunity right from the beginning (conferences, visits, etc.) to meet people, leave good impressions, and build useful connections. This is probably the hardest and most overlooked part of being a PhD student. The only way to learn is to observe how others do it and work on doing it well right from the beginning. It gets easier with time.

Be confident:
A professor/researcher is a leader in research and a mentor to budding researchers. It is thus very important to believe in yourself and your research. If you yourself do not believe in your abilities to be a leader at the forefront of research, it’s hard to convince others to invest in you and believe in your future success. Building confidence comes from understanding your own strengths and abilities to grow in the future, avoiding direct comparisons to others, and learning to internalize criticism constructively.
minesh_full
Q: What writing advice can you give to students who might be drafting their first paper?
Minesh Patel is the lead author on a recent paper that won the Best Paper Award at DSN in June 2019:
Understanding and Modeling On-Die Error Correction in Modern DRAM: An Experimental Study Using Real Devices, DSN, June 24 - 27, 2019, Portland, Oregon

Minesh: We try to approach writing with the audience always in mind. Readers range from expert reviewers to unfamiliar students, and every sentence balances on an edge between presenting a convincing argument and opening up potential attacks, whether this be through poor writing or misleading and incorrect claims. I am pleased that we have a diverse enough group to help ensure that the final paper is sufficiently polished to bring out the best in our work while retaining the voice and style of the project lead.
Haocong_Foto
Haocong Luo is a bachelor student at ShanghaiTech University and was an intern with SAFARI for 8 months in 2019:

Q: How was your experience as an intern with SAFARI?
How do you think the internship might help you in your future studies and future career path?
As an undergraduate student, my internship at SAFARI was an invaluable experience of getting my hands on computer architecture research, cultivating a proper research mindset, and working with other smart minds.

Doing research differs a lot from regular course works. To be honest, not every part of research is as ideal as I expected. However, SAFARI has taught me to enjoy the creative part of generating ideas and critical thinking while working hard and rigorously to make sure that the value of the work is demonstrated at its best. Professor Mutlu was a great help to me in guiding me on research methodologies and providing vital feedback and insights.

Learning is also an essential part of SAFARI. I have significantly extended my horizon on various computer architecture topics through reading groups and frequent discussions with other members of the group. People in SAFARI have diverse backgrounds, but all of them are very kind and helpful when I turned to them. My work could have been much tougher without their generous sharing of expertise and experiences. I really enjoyed the easy-going atmosphere where group members are encouraged to share their progress, and the discussions of new ideas, no matter big or small, are always promoted.

My experience at SAFARI plays an essential role in determining what to do next for me. By having some substantial research experience, I have verified that I do like doing research and would like to continue doing so in my graduate studies.
