Dear SAFARI friends & colleagues,
We are pleased to share our group highlights from Jan 2022 - July 2023 with you in this next edition of our newsletter. 2022 saw a full return of in-person teaching and conference talks, travel, regular office presence, and collaborations abroad. Our research, education, service, and outreach activities continued at full speed and rigor. Although we were back to teaching in the classroom, we continued to livestream our lectures on our YouTube channel, allowing a global audience to attend our classes, while continuing to democratize education and research. We also continued our SAFARI Live Seminar Series, hosting talks by researchers worldwide, with many exciting talks from leaders in both industry and academia. Our lecture and seminars will continue to be livestreamed, and you can continue to find our seminar recordings, and most of our educational and outreach activities on our YouTube channel.
In our research, we enjoyed presenting work at many top conferences, many in person, and have continued to produce high-quality research at high quantity, thanks to rigorous and close collaboration within our group and with our industrial & academic partners. Our group also took over new offices in the ETH OAT building in Oerlikon, where we are now settling in and sharing the space with many new groups and collaborators. We look forward to continuing our productive and impactful work in the rest of 2023 and beyond (collaboratively with hopefully many of you), expanding to new opportunities and collaborations, and always maintaining a continued dedication to sharing our passion in both research and teaching globally.
We wish you a wonderful second half of 2023 filled with good health, happiness, creativity, optimism, and many great ideas that can change the world positively!

Feb 2022: An Intel 2021 Outstanding Researcher Award went to Onur Mutlu and the SAFARI team for Efficient Compute-in-Memory Architectures. His emerging-workload-driven research has led to open-source benchmark suites that help hardware-software co-design and exploration for near-memory architecture. His team’s research has also led to innovative near-memory architectures for deep learning and genomics applications.

June 2022:
EU Horizon Project BioPIM kick-off
We kicked off our newly funded EU Horizon research project, BioPIM, led by Can Alkan at Bilkent University, together with 6 other institutions this spring. Juan Gómez Luna and Mohammed Alser are leading the research activities at ETH.
|
|
|
The goal of BioPIM is the realization of cheap, ultra-fast, and ultra-low energy mobile genomics that eliminates the current dependence of sequence analysis on large and power- hungry computing clusters/data centers commonly based on FPGAs or GPUs.

SAFARI Workshops and Tutorials 2023
|
|
|
|
|
|
Our Real-world PIM tutorial focuses on the latest advances in PIM technology, workload characterization for PIM, and programming and optimizing PIM kernels. We (1) provide an introduction to PIM and taxonomy of PIM systems, (2) give an overview and a rigorous analysis of existing real-world PIM hardware, (3) conduct hand-on labs about important workloads (machine learning, sparse linear algebra, bioinformatics, etc.) using real PIM systems, and (4) shed light on how to improve future PIM systems for such workloads.
