The
first Data Prefetching Championship (DPC) is a
competition for data prefetching algorithms.
Contestants will be given a fixed storage budget to implement their best prefetching algorithms on a common evaluation framework
provided by the DPC organizing committee. What's New: Objective The
goal for this competition is to compare different data prefetching
algorithms in a common framework. Prefetchers for
both the level 1 (L1) and level 2 (L2) data caches must be implemented within
a fixed storage budget as specified in the competition rules. Submissions
will be evaluated based on their performance on a set of benchmarks on the
framework provided by the organizing committee. Prizes The
champion will receive a trophy commemorating his/her triumph. Selected top
contestants will have their work published in a special issue of the Journal
of Instruction-Level Parallelism (JILP). In addition to the top performance
champion, the program committee will select the best technical paper from all
submissions, which does not necessarily have to be that of the champion. All
source code, write-ups and performance results will be made publicly
available through the DPC website. Submission Requirements Each
contestant is allowed a maximum of three submissions to the competition. Each
submission should include the following: o Abstract:
A 300-word abstract summarizing the submission. In addition, the abstract
should include the author names, their affiliations, and the email address of
the contact author. o Paper:
This will be a conference-quality write-up of the prefetching
algorithm, including references to relevant related work. The paper must
clearly describe how the algorithm works, how it is practical to implement,
and how it conforms to the contest rules. The paper must be written in
English and formatted as follows: no more than four pages, single-spaced,
two-column format, minimum 10pt Times New Roman
font. The paper should be submitted in .pdf format,
and should be printable on letter-size paper with one-inch margins. A
submission will be disqualified if the paper does not clearly describe the
algorithm that corresponds to the submitted code. Papers that do not conform
to the length and format rules will only be reviewed at the program
committee’s discretion. o Prefetcher code: A
single C++ header file that can be included in the provided infrastructure
must be submitted along with the paper as a separate file. This code must be
well-commented so that it can be understood and evaluated. Unreadable or
insufficiently documented code will be rejected by the program committee. The
file sample_prefetcher.h from the infrastructure is
distributed with a simple prefetcher, and should be
replaced with the contestant’s code. The prefetcher
code should be compiled and run on the existing infrastructure without
changing any code or Makefile, and should NOT
require any library code that is not part of C++. More details on where to submit these files will be
available soon. Competition Rules The
competition will proceed as follows. The contestant will be responsible for
implementing and evaluating their algorithm in the distributed framework. The
framework itself is provided as a binary and cannot be modified (except for
the prefetcher header file that implements the prefetching algorithm). Submissions will be taken,
compiled and run with the original version of the framework. The contestants
will be ranked on the basis of the measured performance of their prefetching algorithms. Each contestant will get three
scores, one for each of three
configurations, that measure the geometric mean
of their prefetching algorithm speedups across a
set of (undistributed) benchmarks. The overall score is the sum of these
three scores. For example, if a contestant has scores of 1.05, 1.03 and 0.99
for the three configurations, his/her overall score is 3.07. Acceptance Criteria In
the interest of assembling a quality program for workshop attendees and
future readers, there will be an overall selection process, of which
performance ranking is a key component but not the sole component. To be considered, submissions must conform to the
submission requirements described above. Submissions will be selected to appear in the
workshop on the basis of the performance ranking, novelty, and overall
quality of the paper and commented code. Novelty is not a strict requirement,
for example, a contestant may submit his/her previously published prefetchers or make incremental enhancements to
previously proposed prefetchers. In such cases,
performance is a heavily weighted criterion, as is overall quality of the
paper (for example, analysis of new results on the common framework, etc.).
Conversely, a very novel submission that is not necessarily a top performer
in the competition, will be considered not just from a performance standpoint
but also on the basis of insights etc. Description of the Simulation
