ISCA 2025

Welcome to Tokyo and the 2025 International Symposium on Computer Architecture! This year, the conference will be held at Waseda University, a private university founded in 1882 by Prime Minister Shigenobu Okuma. It is home to 13 undergraduate schools and 19 graduate schools. As of 2024, it is attended by 38,987 undergraduate students and 8,499 graduate students. Its famous alums include eight prime ministers, Masaru Ibuka (Sony Founder), Tadashi Yanai (UNIQLO Founder), and many other notable graduates. This rich academic environment will provide an intellectually fertile backdrop to our meeting

ISCA offers an extraordinary technical program this year, and we know that all attendees, including authors, academic researchers, and practitioners, will significantly benefit from it. First, we will have 20 workshops and 13 tutorials on June 21st and 22nd. At the end of the two days, in the afternoon on June 22nd, as an ISCA’25 special event, Yale Patt (University of Texas at Austin) will inspire us with an invited talk, “Solving the Sustainability Problem -- What must come first. ...and 2nd. ...and 3rd." It will then be capped by a special panel of distinguished panelists, organized and moderated by Dejan S. Milojičić (HPE) on “Sustainable Computer Architecture.” The panelists will include Wen-Mei Hwu (NVIDIA), Norm Jouppi (Google), Hironori Kasahara (Waseda University), Yale Patt (University of Texas at Austin), Guri Sohi (University of Wisconsin-Madison), and Carole-Jean Wu (Meta). Over the three following days, June 23rd-25th, the main symposium will feature a strong set of papers, punctuated by a remarkable lineup of invited speakers, luminaries in our field: Satoshi Matsuoka (RIKEN, Japan) on June 23rd, Todd Austin (University of Michigan) and Fitsum Assamnew Andargie (Addis Ababa University, Ethiopia) on June 25th. We expect that all the activities on this whole program will contribute to making ISCA a continued leading influence on the computer research field.

But it won’t be all work and no play: we hope that you and any companion will enjoy at least some of the social activities we have arranged for you:

• Reception: After the panel on June 22nd, Rihga Loyal Hotel Tokyo, next to the main venue,
• Family sightseeing bus tour for up to 30 people: In the afternoon of June 23rd, offered by TCVB (Tokyo Convention & Visitors Bureau),
