There is an urgent need for an effective performance anomaly detection method that can be used within the production environment to avoid any late detection of unexpected system failures. To address this challenge, we introduce, TRACK, a new black-box training workload configuration optimization with a neural network driven methodology to identify anomalous performance in an in-memory Big Data Spark streaming platform. The proposed methodology revolves around using Bayesian optimization to find the optimal training dataset size and configuration parameters to train the model efficiently. TRACK is validated on a real Apache Spark streaming system and the results show that the TRACK achieves the highest performance (95% for F-score) and reduces the training time by 80% to efficiently train the proposed anomaly detection model in the in-memory streaming platform.","PeriodicalId":419829,"journal":{"name":"Proceedings of the 13th EAI International Conference on Performance Evaluation Methodologies and Tools","volume":"39 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120910370","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}

An immersive experience of high quality, however, requires a high bandwidth connection. The latest generation of these headsets support wireless connectivity and rely on a battery to power the headset. With advancements in 5G technology, soon these headsets would be able to connect to the network directly. To provide a similar immersive and uninterrupted experience to the users, the headsets would need to take into account the intermittent behavior of the wireless channel. In this paper we model the streaming of 360° videos on a VR headset using a wireless channel. We model both the intermittent behavior of the wireless channel as well as the prediction of the head position of the user. The MDP based streaming algorithm we present, guarantees a high Quality of Experience (QoE) for the headset users while ensuring that the resource usage is minimised.","PeriodicalId":419829,"journal":{"name":"Proceedings of the 13th EAI International Conference on Performance Evaluation Methodologies and Tools","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133722674","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 pattern creates product transformation cycles, that allow to re-use parts and renew energy, defining Circular Economy Ecosystems. Such cycles, are very interesting systems from a performance evaluation point of view: in this paper we give a Colored Petri Net perspective to circular economy. In particular, we focus on an example taken from the literature that considers car manufacturing, and we show how we can deal with the problem using standard performance evaluation techniques. Results from performance analysis of the case study, allow to focus on new interesting metrics and performance indicators, that might not be fully studied with conventional techniques applied by expert of the economical domain.","PeriodicalId":419829,"journal":{"name":"Proceedings of the 13th EAI International Conference on Performance Evaluation Methodologies and Tools","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115544832","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}

In fork-join systems, dynamic adaptation of the server speeds can significantly reduce system power consumption while maintaining high throughput. In previous work, we studied a rate adaptation policy that dynamically chooses server speeds based on the difference in join-queue lengths, with each server knowing only its own join-queue length and that of one other server. In this work, we increase the information available to each server, and choose speeds based on the knowledge of the join-queue lengths of two other servers. We show that, under a specific canonical configuration of the service rates, the new system has exactly the same throughput and subtask dispersion as before, but with reduced power consumption. We use time-reversal analysis to derive the exact stationary performance of this new model under saturation conditions, and use simulation to study more general cases.","PeriodicalId":419829,"journal":{"name":"Proceedings of the 13th EAI International Conference on Performance Evaluation Methodologies and Tools","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128776848","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}

We propose to bound the output distribution in order to overcome the distribution size explosion.

Previous work extended the continuous dynamics to linear time-invariant systems, simulated via a quantized state space approach in the tool HYPEG. This method discretizes the state space to approximate solutions of the linear time-invariant systems. This paper extends the set of equations to non-linear ordinary differential equations (ODEs) by adding well known time-discrete methods. These can now be integrated in an extendable way, since HYPEG has been adapted to deal with time-discretization as part of this work. The results of the new implementation are validated on a battery model with linear ODEs and furthermore used to compute results for a heating model with non-linear ODEs.","PeriodicalId":419829,"journal":{"name":"Proceedings of the 13th EAI International Conference on Performance Evaluation Methodologies and Tools","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126518699","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}

Due to this dual role of the machines, the system exhibits an intricate relation between the processing rate of products and the performance of the repairer. To characterize this relation, we analyze this model under a Halfin-Whitt inspired scaling regime, where we amplify the arrival rate of products, the repair speed of the repairer and the number of machines appropriately. The resulting limiting stationary distribution is elegant, allows for a closed-form expression and provides intuition on the system's behavior resulting from the machines' dual role. With numerical results we illustrate the convergence, and assess under which conditions the limiting distributions lead to accurate approximations. Next to this valuable insight, the analysis in this paper can be viewed as a first step towards a unifying scaling analysis for general closed queueing networks.","PeriodicalId":419829,"journal":{"name":"Proceedings of the 13th EAI International Conference on Performance Evaluation Methodologies and Tools","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131685904","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}

MDCStream is built on MDCGen, therefore showing a high flexibility for creating a wide diversity of data scenarios.
