The individual applications are composed of one or more threads to fully utilize the available CPU cores, but this approach can incur serious overheads. The thread-per-core architecture has emerged to reduce these overheads, but it also has its challenges from thread synchronization and OS interfaces. Applications can mitigate both issues with different techniques, but their impact on application tail latency is an open question. We measure the impact of thread-per-core architecture on application tail latency by implementing a key-value store that uses application-level partitioning, and inter-thread messaging and compare its tail latency to Memcached which uses a traditional key-value store design. We show in an experimental evaluation that our approach reduces tail latency by up to 71 % compared to baseline Memcached running on commodity hardware and Linux. However, we observe that the thread-per-core approach is held back by request steering and OS interfaces, and it could be further improved with NIC hardware offload.","PeriodicalId":405320,"journal":{"name":"2019 ACM/IEEE Symposium on Architectures for Networking and Communications Systems (ANCS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134273042","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}

Such flexibility opens up the possibility to move data processing inside network elements for high-performance computation, known as in-network processing. However, existing ICN architectures are limited in terms of (i)in-network processing and (ii)data plane programming abstractions. Such architectures can benefit from Complex Event Processing (CEP), an in-network processing paradigm to efficiently process data inside the data plane. Yet, it is extremely challenging to integrate CEP because the current communication model of ICN is limited to consumer-initiated interaction that comes with significant overhead in number of requests to process continuous data streams. In contrast, a change to producer-initiated interaction, as favored by CEP, imposes severe limitations for request-reply interactions. In this paper, we propose an in-network CEP architecture, INETCEP that supports unified interaction patterns (consumer- and producer-initiated). In addition, we provide a CEP query language and facilitate CEP operations while increasing the range of applications that can be supported by ICN. We provide an open source implementation and evaluation of INETCEP over an ICN architecture, Named Function Networking, and two applications: energy forecasting in smart homes and a disaster scenario.","PeriodicalId":405320,"journal":{"name":"2019 ACM/IEEE Symposium on Architectures for Networking and Communications Systems (ANCS)","volume":"90 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126219379","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}

Most of current GPGPU Network-on-Chips (NoCs) employ topology adapted from CPUs, such as mesh and crossbar. However, the trade-off between performance and cost for such networks is sub-optimal, due to the unique traffic pattern of GPUs. In this work, we propose a novel NoC architecture called fused fat tree which modifies the fat tree to match GPU traffic pattern. By separately connecting memory controllers and computing cores to tree roots and leaves, protocol deadlocks can be avoided using just one physical network. However, this modification removes the advantage of path diversity in the original fat tree topology and makes the network vulnerable to hotspot-caused congestion. To solve this problem, we propose to fuse routers with side links to create multiple paths. A load-balancing routing algorithm is also proposed in order to increase network throughput. We also propose a novel preemptive bandwidth allocation scheme to improve resource utilization by taking advantage of request message slacks. Our evaluation results show that our design can improve performance by 46% while achieving 27 % and 25 % area and energy savings on the average.","PeriodicalId":405320,"journal":{"name":"2019 ACM/IEEE Symposium on Architectures for Networking and Communications Systems (ANCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130861708","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}

The participating institutions can share distributed P4 resources over international research and education networks, as well as initiate international P4 research collaboration projects. Initial network scenarios in this research testbed are Software-Defined Network Exchanges (SDXs), Network and Cloud Testbed Networks, Science Networks, and Campus Research Networks. These four network scenarios require multi-tenant support. Current P4Runtime specifications include a Multi-Controller design for twofold: Control Plane Partition and Redundancy [2]. However, the current P4Runtime does not implement Control Plane partition to support multi-tenant service on a switch.
