International Symposium on Highly Efficient Accelerators and Reconfigurable Technologies (HEART 2021)

Follow us on Twitter: @heart_symp

We are happy to announce the HEART'21 Virtual Conference Program that includes two exciting keynotes, 8 regular research talks and a Phd forum with lightning talks and a virtual poster session.

In addition, we will have three special sessions on current hot topics:

To facilitate informal discussions between participants we will provide an interactive space to socialize in the conference breaks.

Thanks to our generous sponsors, the HEART'21 symposium can be held as a free online event for all participants. To attend the conference, a registration is required due to legal reasons (privacy policy, etc.). The registration portal will be open from June 11.


The International symposium on Highly Efficient Accelerators and Reconfigurable Technologies (HEART) is a forum to present and discuss new research on computing systems utilizing acceleration technology. The main theme of HEART is achieving high efficiency with accelerators, which is of utmost importance across a wide spectrum of computing systems. In the high performance computing and data center domains, high efficiency mostly relates to performance, while in the mobile and IoT space research communities think about accelerators more from a power/energy perspective.

The eleventh edition of HEART will take place as a virtual conference. The symposium will be held from June 21–23 2021.
