<div dir="ltr"><p>The 20th Workshop on Hot Topics in Operating Systems hopes to
bring together researchers and practitioners in computer systems
to engage in a lively discussion on the principles and practices
of building systems software. Continuing the HotOS tradition,
participants will present new ideas and debate future research
agendas in systems research.</p>
<p>We solicit position papers that propose new directions of systems
research, advocate innovative approaches to long-standing
problems, or report on deep insights gained from experience with
real-world systems. We seek early-stage work where the authors can
benefit from community feedback. An ideal submission has the
potential to open a line of inquiry that results in multiple
conference papers by different authors in related venues, rather
than a single follow-on conference paper. The program committee
will explicitly favor papers likely to stimulate reflection and
discussion.</p>
<p>HotOS takes a broad view of systems research. This includes
operating systems, storage, distributed systems, mobile and
embedded systems, virtualization, programming languages,
networking, security, dependability, and manageability, as well as
new systems contributions influenced by other fields such as
hardware design, training and serving machine learning,
verification, economics, social organization, and biological or
other nontraditional computing systems.</p>
<p>Research and position papers as well as panel proposals must be
received by Thursday January 15, AoE. This is a hard deadline.
Papers and proposals should be submitted as PDF files via <span><a href="https://www.google.com/url?q=https://hotos25.hotcrp.com/&sa=D&source=editors&ust=1726851695132824&usg=AOvVaw3SrvjPqf9j2_vpsyLZn0NL" target="_blank">the
web submission form</a>. Please select your submission type on
the form (paper or proposal).</span></p>
