Event

I recently attended SC23, one of the largest conferences in HPC. It was my first time attending such a large conference in person and I was amazed at the variety of topics, including ones I had never heard of before!

I really enjoyed listening to some of the talks on healthcare, privacy, and machine learning as well as speaking with some of the presenters. Going through the exhibit hall was also an interesting experience as I had the chance to talk at a more relaxed pace. While I spent most of my time at booths for research institutes, I also had the chance to see how some companies are developing research ideas in to commercial products.

Overall, I had a great time attending the conference. I hope other students get the chance to go to similar conferences and broaden their knowledge on research topics in HPC.

Our new supercomputer “AOBA-S,” which started operation in August 2023, has been registered in the November 2023 Top500 list.  The list was announced on November 14, 2023 (local time) at SC23, an international conference on high-performance computing held in Denver, USA. AOBA-S was ranked 10th in the HPCG list and 50th in the Top500 list.

Assistant Professor Takahashi presented the following paper at the Fourth International Workshop on Quantum Computing Software held in conjunction with SC23. In this paper, we prototyped and evaluated a batched state vector simulator on a vector processor for simulating many quantum circuits in parallel, for the purpose of studying noisy quantum computers and variational quantum algorithms.

We held a Imoni Festival in our laboratory!
We made two kinds, one miso-flavored and the other soy sauce-flavored, and both were delicious!
It was a little cold, but everyone who attended seemed to enjoy it very much!

Assistant Professor Keichi Takahashi presented the following paper at the 191st IPSJ SIGHPC meeting held at the Graduate School of Information Science and Technology, Tohoku University on September 26-27, 2023. This paper reports the initial performance evaluation of Cyberscience Center’s new supercomputer, AOBA-S, which started operation in August 2023.

As a welcome party for B3 and a farewell party for Dominik and Sun, we had a BBQ with our lab members.
Everyone enjoyed the BBQ very much after a long absence!

Koda, M1 student in our laboratory, received the Outstanding Effort Award for his paper presented at xSIG 2023.

This award recognizes “the time and effort spent on the implementation and data acquisition related to the technical contribution of the paper”, and is an objective recognition of Koda’s efforts. We hope that this award will encourage him to aim higher!

Koda of M1 and Asia of B4 in our laboratory presented the following papers at xSIG 2023 and 190th HPC meeting held at SWoPP 2023, respectively.

After the presentation, there were many questions from the audience, indicating that there was a lot of interest in the presentation.
Let’s use this as a springboard for further development of our research!

Tohoku University Cyberscience Center had a unveiling visiting tour of new supercomputer AOBA-1.5. Prof. Takizawa explained the detail of the supercomputer, and the explanations appeared in some newspapers and TV programs.
