Call for Papers
The JSSPP workshop addresses all scheduling aspects of parallel processing, including cloud, grid, HPC & HTC as well as “mixed/hybrid” or otherwise specific systems.
Large parallel systems have been in production for 30 years, creating the need of scheduling for such systems. JSSPP focus both on traditional parallel cluster/HPC/HTC systems as well as more recent cloud-based systems.
Nowadays, parallel processing is much more dynamic and connected. Many workloads are interactive and make use of variable resources over time. Complex parallel infrastructures can now be built on the fly, using resources from different sources, provided with different prices and quality of services. Capacity planning became more proactive, where resources are acquired continuously, with the goal of staying ahead of demand. The interaction model between job and resource manager is shifting to one of negotiation, where they agree on resources, price, and quality of service. Also, “hybrid” systems are often used, where the (virtualized) infrastructure is hosting a mix of competing workloads/applications, each having its own resource manager that must be somehow co-scheduled. These are just a few examples of the open issues facing our field.
From its very beginning, JSSPP has strived to balance practice and theory in its program. This combination provides a rich environment for technical debate about scheduling approaches including both academic researchers as well as participants from industry.
Building on this tradition, JSSPP welcomes both regular papers as well as descriptions of Open Scheduling Problems (OSP) in large scale scheduling (see bellow). Lack of real-world data often substantially hampers the ability of the research community to engage with scheduling problems in a way that has real world impact. Our goal in the OSP venue is to build a bridge between the production and research worlds, in order to facilitate direct collaborations and impact.
Call for Regular Papers
JSSPP solicits papers that address any of the challenges in parallel scheduling, including:
- Design and evaluation of new scheduling approaches.
- Performance evaluation of scheduling approaches, including methodology, benchmarks, and metrics.
- Workloads, including characterization, classification, and modeling.
- Consideration of additional constraints in scheduling systems, like job priorities, price, accounting, load estimation, and quality of service guarantees.
- Impact of scheduling strategies on system utilization, application performance, user friendliness, cost efficiency, and energy efficiency.
- Scaling and composition of very large scheduling systems.
- Cloud provider issues: capacity planning, service level assurance, reliability.
- Interaction between schedulers on different levels, like processor level as well as whole single- or even multi-owner systems
- Interaction between applications/workloads, e.g., efficient batch job and container/VM co-scheduling within a single system, etc.
- Experience reports from production systems or large scale compute campaigns.
Call for Open Scheduling Problems (OSP)
JSSPP welcomes descriptions of open problems in large scale scheduling. We believe that clearly described real-world scheduling problems will help both the production and the scientific community to bridge the gap that often prevents adoption of newly proposed scheduling techniques in practice.
Effective scheduling approaches are predicated on three things:
- A concise understanding of scheduling goals, and how they relate to one another.
- Details of the workload (job arrival times, sizes, shareability, deadlines, etc.)
- Details of the system being managed (size, break/fix lifecycle, allocation constraints)
Submissions must include concise description of the key metrics of the system and how they are calculated, as well as anonymized data publication of the system workload and production schedule. Detailed descriptions of operational considerations (maintenance, failure patterns, fault domains) are also important. Ideally, anonymized operational logs would also be published, though we understand this might be more difficult.
We envision that these papers will provide sufficiently detailed information to be able to develop new scheduling approaches, which can be robustly compared with the schedules used in production facilities, and other approaches to solve the same problems.
Paper formatting requirements for OSP-related submissions are the same as for regular papers and are available in the Submission section.
Venue and virtual venueJSSPP 2021 is being planned for Portland, Oregon May 21. However, remote paper presentation and attendance will be allowed to accommodate various constraints and restrictions caused by the pandemic. A fully virtual workshop is being planned at the same time, in case it is not possible to cellebrate JSSPP presentially at all. In virtual format, we will use videoconferencing and upload workshop-ready versions of papers at the workshop website beforehand. After the workshop the recording of the talks and the slides of all presentations will be shared on the JSSPP website and JSSPP youtube channel. The virtual format was very successful in JSSPP 2020, with great participant attendance and engagement with the presenters.
