The JSSPP workshop addresses all scheduling aspects of parallel computing, including cloud, grid, HPC & HTC, as well as "mixed/hybrid" or otherwise specific systems.

For the last 30 years, such parallel systems have grown in capacity and complexity, creating the need for new scheduling systems to govern them. JSSPP focuses both on such problems for traditional parallel cluster/HPC/HTC systems as well as more recent cloud-based systems.

Nowadays, parallel computing supports extremely heterogeneous workloads in very dynamic and connected environments. Many workloads are interactive and make use of variable resources over time. Complex parallel infrastructures can now be built on the fly, sourcing compute capacity from different providers simultaneously, while each offers different prices and quality of services. Capacity planning has become 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 below). 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 but not limited to:

Call for Open Scheduling Problems (OSP)

NEW topic logo

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:

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 venue

JSSPP 2023 is being planned for May 19 in in St. Petersburg, Florida USA. However, remote paper presentation and attendance will be likely 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 celebrate 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, 2021 and JSSPP 2022, with great participant attendance and engagement with the presenters.
