In these clusters, the dominate programming model is the Message Passing Interface (MPI), so the MPI library has a key role in resource usage and performance. To obtain maximal performance, many clusters deploy a high-speed interconnect between compute nodes. One such interconnect, InfiniBand, has been gaining in popularity due to its various features including Remote Data Memory Access (RDMA), and high-performance. As a result, it is being deployed in a significant number of clusters and has been chosen as the standard interconnect for capacity clusters within the DOE Tri-Labs. As these clusters grow in size, care must be taken to ensure the resource usage does not increase too significantly with scale. In particular, the MPI library resource usage should not grow at a rate which will exhaust the node memory or starve user applications. In this paper we present our findings of current memory usage when all connections are created and design a message coalescing method to decrease memory usage significantly. Our models show that the default configuration of MVAPICH can grow to 1GB per process for 8K processes, while our enhancements reduce usage by an order of magnitude to around 120 MB per process while maintaining near-equal performance. We have validated our design on a 575-node cluster and shown no performance degradation for a variety of applications. We also increase the message rate attainable by over 150%.","PeriodicalId":278535,"journal":{"name":"Seventh IEEE International Symposium on Cluster Computing and the Grid (CCGrid '07)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123936292","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 parallel applications and supporting cluster services often need to share system-wide resources. The coordination of these applications is typically managed by a distributed lock manager. The performance of the lock manager is extremely critical for application performance. Researchers have shown that the use of two sided communication protocols, like TCP/IP (used by current generation lock managers), can have significant impact on the scalability of distributed lock managers. In addition, existing one sided communication based locking designs support locking in exclusive access mode only and can pose significant scalability limitations on applications that need both shared and exclusive access modes like cooperative/file-system caching. Hence the utility of these existing designs in high performance scenarios can be limited. In this paper, we present a novel protocol, for distributed locking services, utilizing the advanced network-level one-sided atomic operations provided by InfiniBand. Our approach augments existing approaches by eliminating the need for two sided communication protocols in the critical locking path. Further, we also demonstrate that our approach provides significantly higher performance in scenarios needing both shared and exclusive mode access to resources. Our experimental results show 39% improvement in basic locking latencies over traditional send/receive based implementations. Further, we also observe a significant (up to 317% for 16 nodes) improvement over existing RDMA based distributed queuing schemes for shared mode locking scenarios.","PeriodicalId":278535,"journal":{"name":"Seventh IEEE International Symposium on Cluster Computing and the Grid (CCGrid '07)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122170011","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}

Little of it, however, has addressed the more challenging issue of dynamically establishing spontaneous, multihop ad hoc mobile grids, and then only in preliminary form. In such grids, resource discovery and scheduling have been traditionally approached separately in the literature. In our view, this is an inappropriate dichotomy as regards multihop ad hoc mobile grids. In this paper, we propose a resource discovery and scheduling protocol for mobility (DICHOTOMY), which allows resource provisioning to be scheduled among the most resourceful nodes in the mobile grid, while mitigating the overhead of discovery messages exchanged among them. Our experimental results in a testbed and in a simulation platform show that the protocol provides efficient load balancing between nodes under an increasing number of requests, and scales well with respect to an increasing number of nodes in comparison with traditional broadcast-based solutions for service discovery.","PeriodicalId":278535,"journal":{"name":"Seventh IEEE International Symposium on Cluster Computing and the Grid (CCGrid '07)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117335415","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}
