1st PEaCE workshop in Vienna

I’d like to draw attention to the 1st International Workshop on Performance and Conformance of Workflow Engines (PEaCE), which is co-located with the 5th European Conference on Service-Oriented and Cloud Computing (ESOCC 2016) and takes place on September 5th, 2016, in Vienna, Austria. The workshop is a joint initiative with colleagues from the universities of Stuttgart and Lugano, all of whom are working on workflow engine benchmarking. We welcome not only scientific contributions, but are also looking for contributions from industry. Here is the CfP:


1st International Workshop on Performance and Conformance of Workflow Engines (PEaCE)
at the
5th European Conference on Service-Oriented and Cloud Computing (ESOCC 2016)
2016-09-05 to 2016-09-07, Vienna, Austria

Workflow management systems provide platforms for delivering complex service-oriented applications that need to satisfy enterprise-grade quality of service requirements such as dependability and scalability. Benchmarking is an established practice that helps to drive continuous improvement of technology by setting a clear standard and measuring and assessing its performance. For example, transaction processing benchmarks have been introduced since a long time and over decades they have been instrumental to achieve an enormous performance improvement of database technology, e.g., with the TPC family of benchmarks. Conversely, benchmarks for service oriented computing in general and workflow management systems in particular have started to appear only recently and there is no currently accepted standard benchmark.

Any vendor can claim that their product is standard compliant while still implementing different subsets or interpretations of the standard, since there is no certification authority for both of the most popular and widespread business process languages standards BPEL and BPMN. The different interpretations and implementations of the standards led and still lead to vendor lock-ins as porting a standard compliant workflow involves too much effort, and sometimes is not possible at all – effectively killing the standard inherent argument for portability. Benchmarks for standard conformance have not been around for long in the area of WfMSs, and still lack scientific foundation in their creation and execution.

This workshop aims to bring researchers and industry together in the topics benchmarking and standard conformance in the area of workflow management systems. Workflows is an established way of implementing service composition. The benefit for the community will be to learn about the state of the art in services composition using workflows, both from the research and the industry perspective. Therefore, we also welcome experience reports of industry.

## Topics

Authors are invited to submit novel contributions in the above mentioned problem domain. Relevant topics include, but are not limited to:

1. Benchmarking performance of workflow management systems, e.g.,
– Performance metrics for workflow management systems
– Applications for benchmarking performance of workflow management systems
– Performance benchmarks and evaluations for workflow management systems
– Impacts from other performance areas on workflow engine performance measurement, e.g. underlying databases
– Workflow management systems architecture and its impact on performance
2. Measuring conformance of workflow management systems, e.g.,
– Applications for benchmarking conformance of workflow management systems
– Conformance benchmarks and evaluations for workflow management systems
– Static analysis capabilities of workflow management systems
– Expressiveness and workflow pattern support in workflow management systems
3. Benchmarking and measuring workflow management systems in the cloud, e.g.,
– Methods for testing cloud-based workflow management systems
– Evaluations of workflow management systems in the cloud
– Cloud-specific performance indicators for workflow management systems
– Cloud-specific challenges to workflow management systems benchmarking
4. Benchmark design, e.g.,
– Workload models of workflows
– Micro benchmarks for workflows
– Domain models for workflow benchmarks
– Methods for deriving conformance test suites
– Methods for deriving representative workflow models from workflow collections
– Benchmark reproducibility
– Benchmark efficiency
5. Benchmark use cases, e.g.,
– Workflow management systems comparison, e.g., proprietary vs. open source
– Workflow management systems selection
– Industrical case studies on workflow management systems evaluation
– Standardization initiatives for workflow engine benchmarks
– The impact of benchmarks on workflow management systems evolution
– Benchmarks for ensuring the quality of evolving systems
– Benchmarking of components of workflow engines

## Submission

The workshop accepts regular research papers and industry talks. Submissions will be reviewed by at least three reviewers each in order to assure general fitness regarding content, readability and scope and to give feedback to the authors. Papers may be accepted or rejected depending on innovation, technical soundness and presentation clarity. All accepted contributions will be published in the on-site proceedings, but only research papers will be included in the post-workshop proceedings. The post-workshop research proceedings are planned to be published in Springer CCIS (acceptance pending).

Regular research paper submissions should be formatted according to the LNCS proceedings guidelines and the template and they should not exceed 12 pages. A paper might be accepted as a full paper (12 pages) or as a short paper (8 pages). Accepted papers will be included in the on-site and the post-workshop proceedings.

Industry talks may be submitted as two page overview paper or an extended abstract and should follow the LNCS proceedings guidelines and the template. Industry talks provide a forum to demonstrate implementations of techniques and algorithms in the topic area of the workshop. We also welcome and encourage experience reports from industry. Industry talks will receive a regular presenation slot at the workshop. The paper should outline the main idea of the talk and what the audience can expect during the presentation. All accepted talks will be published in the on-site proceedings.

Papers can be uploaded via the submission system:
