Traces Synchronization in Distributed Networks

Eric Clément, Michel Dagenais
2009 Journal of Computer Systems, Networks, and Communications  
The time offset computation imprecision, associated with asymmetric network delays and operating system latency in message sending and receiving, is amortized over a large time interval through a linear  ...  The resulting accuracy is such that it is possible to estimate the clock offsets in a distributed system, even with a relatively low volume of messages exchanged, to within the order of a microsecond while  ...  The message in each direction with the smallest time is thus retained to compute the roundtrip time and then the time offset and error margin between the two nodes.  ...

HopsFS: Scaling Hierarchical File System Metadata Using NewSQL Databases [article]

Salman Niazi , Mikael Ronström KTH - Royal Institute of Technology
2017 arXiv   pre-print
In this paper, we introduce HopsFS, a next generation distribution of the Hadoop Distributed File System (HDFS) that replaces HDFS' single node in-memory metadata service, with a distributed metadata service  ...  Recent improvements in both the performance and scalability of shared-nothing, transactional, in-memory NewSQL databases have reopened the research question of whether distributed metadata for hierarchical  ...  During this time no file system metadata operation can be performed. Our failover tests were favorable to HDFS, as the amount of metadata stored by NNs in the experiment is minimal.  ...
