GNOSIS follows a query-driven approach where users can write complex event queries using Multimodal Event Processing Language (MEPL). The system models incoming multimodal data into an evolving Multimodal Event Knowledge Graph (MEKG) using an ensemble of deep neural network (DNN) and machine learning (ML) models and applies a neuro-symbolic approach for event matching. GNOSIS follows a serverless paradigm where its different components act as independent microservices and can be deployed across different nodes with optimized edge support. The paper demonstrates two multimodal use case queries from Occupational Health and Safety and Accessibility domain.","PeriodicalId":246858,"journal":{"name":"Proceedings of the 22nd International Middleware Conference: Demos and Posters","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122100232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These attributes make them a natural substrate for data analytics workflows. However, the impossibility of direct communication between functions makes the execution of workflows challenging. The current practice to share intermediate data among functions is through remote object storage (e.g., IBM COS). Contrary to conventional wisdom, the performance of object storage is not well understood. For instance, object storage can even be superior to other simpler approaches like the execution of shuffle stages (e.g., GroupBy) inside powerful VMs to avoid all-to-all transfers between functions. Leveraging a genomics pipeline, we show that object storage is a reasonable choice for data passing when the appropriate number of functions is used in shuffling stages.","PeriodicalId":246858,"journal":{"name":"Proceedings of the 22nd International Middleware Conference: Demos and Posters","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117151919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study conducts an analysis of Kafka's network fault tolerance capabilities, one of the widely used distributed stream processing system (DSPS). Across different Kafka configurations, we observed that Kafka is fault-tolerant towards network faults to some degree, and we report observations of its shortcomings. We also define a network fault-tolerance benchmark on which other DSPSs can be evaluated.","PeriodicalId":246858,"journal":{"name":"Proceedings of the 22nd International Middleware Conference: Demos and Posters","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123338713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tracking such call graphs is crucial to diagnose and resolve performance issues. This paper presents DyMonD, a holistic framework that dynamically monitors the software layer of the cloud network to track dependencies between application components and derive performance metrics. It adapts a deep learning model to identify the service type of each component, and visualizes all information in form of a call graph. Our evaluation results confirm that DyMonD can infer the proper call graph and identify the services at run-time with acceptable overhead and good accuracy.","PeriodicalId":246858,"journal":{"name":"Proceedings of the 22nd International Middleware Conference: Demos and Posters","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125799314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This short note discusses the integration of the ZK-STARK-based proof system into the OpenLibra blockchain.
