EuroSys Review Process
Use this to model the decision machinery around a EuroSys submission. Facts
below are the 2026/2027 cycles as rendered on 2026-07-08 from the EuroSys CFPs
and conference pages; per-round mechanics (rebuttal windows, review counts,
online PC meeting format) are set inside each HotCRP instance — 待核实 there.
One conference, two juries
Each EuroSys edition accepts papers through two temporally separate rounds —
for 2027: spring (papers May 14, 2026 → notification August 21, 2026) and fall
(papers September 24, 2026 → notification January 29, 2027). Both cohorts are
published in the same proceedings and presented at the same April conference.
Strategically this means:
- Your competition is round-local; the PC calibrates within the round it reads.
- A spring reject cannot simply "try again in the fall": the CFP bars a
rejected paper from returning until the same round of the next edition —
a full year, not one deadline.
- A revision offer, by contrast, explicitly bridges rounds: revise-and-resubmit
at the subsequent deadline, judged against the issued condition list.

"One-shot" is literal: the revision is evaluated once, against the conditions,
by a process designed for continuity with the original reviews. There is no
second revision offer downstream of the first.
Who is reading
- A double-blind HotCRP process: reviewers do not see authors, and conflicts
declared at abstract registration drive assignments.
- The PC spans the breadth of European and international systems research —
kernels, distributed systems, storage, cloud runtimes, virtualization,
systems security, and increasingly systems-for-ML. Expect at least one
reviewer whose home sub-area differs from yours; the paper's framing must
carry them.
- EuroSys has repeatedly run a Shadow PC (e.g.,
2026.eurosys.org/shadow-pc.html),
where early-career researchers review real submissions in parallel as
training. Practical consequence: write for a rigorous but possibly junior
reader, and expect the community's reviewing norms to be unusually explicit
and well-documented.
What moves a PC discussion here
- Verifiable evaluation fairness — tuned baselines, named versions,
disclosed hardware — because the deepest systems-review instinct is to
distrust a benchmark table.
- A mechanism the reviewer can retell — if the design section cannot be
summarized in three sentences at the PC meeting, no champion can defend it.
- Claims scoped to evidence — a paper that says where it loses earns the
credibility spent by every paper that doesn't.
- Deployment plausibility — EuroSys values systems that could run outside
the lab; a purely synthetic setting needs an explicit bridge to practice.
A round from the author's seat
Between the paper gate and notification (roughly fourteen weeks in the
2027 spring round: May 14 → August 21), the author-visible surface is
nearly silent. What happens behind it, in the standard HotCRP shape:
- Bidding and assignment off the registered topics and conflicts.
- First-round reviews; possibly a cut before additional reviews are
commissioned on papers still alive.
- Rebuttal or author-reviewer interaction if the round runs one (待核实
in the round's HotCRP announcements).
- Online PC discussion converging each paper into one of the three bins,
with revision-condition lists drafted for the middle bin.
- Notification, reviews, and — for the middle bin — the condition list.
The author-controllable inputs are all front-loaded: the registered
abstract (bidding quality), the conflicts (assignment sanity), and the
paper itself. Mid-round, the only lever is the response phase, if any.
Conduct boundaries
- No reviewer contact outside the platform, no identity fishing, no
parallel submission of the same work to another archival venue.
- Public talks and preprints during review are governed by the round's
anonymity wording — 待核实 before scheduling a seminar on the submitted
work under its submission title.
Reading your reviews structurally
For each review, extract:
score-driver: the sentence that explains the score (rarely the summary)
fixability: bounded experiment/rewrite -> revision-compatible
identity-level objection -> reject-compatible
round-awareness: does the reviewer propose revision conditions?
Then ask: across reviewers, is there a coherent, enumerable condition list?
yes -> argue toward the revision bin in the rebuttal (if the round has one)
no -> maximize the accept case on the strongest review's terms
Output format
[Round position] spring / fall, and days to its next gate
[Outcome forecast] accept / revision / reject, with the driving signal
[Condition-list coherence] <enumerable fixes or identity-level objections>
[Ban exposure] <date this paper may legally return if rejected>
[待核实] <this round's rebuttal window, review counts, PC-meeting form>
