mNFS: Multicast-Based NFS Cluster
نویسندگان
چکیده
NFS is a distributed file system which is widely used in UNIX environments. Many studies have been worked to improve its I/O performance and scalability. However, existing architectures, which have either single load balancer or meta server, could suffer from single-pointof-failure and unnecessary network delay. We propose a new NFS architecture called mNFS cluster to improve its scalability. Experimental results show that mNFS outperforms both Linux NFS and NFSp by 64% and 99%, respectively.

New Complexity Trade-Offs for the (Multiple) Number Field Sieve Algorithm in Non-Prime Fields
The selection of polynomials to represent number fields crucially determines the efficiency of the Number Field Sieve (NFS) algorithm for solving the discrete log problem in a finite field. An important recent work due to Barbulescu et al builds upon existing works to propose two new methods for polynomial selection when the target field has a composite order. These methods are called the gener...
متن کاملThe Multiple Number Field Sieve with Conjugation and Generalized Joux-Lercier Methods
In this paper, we propose two variants of the Number Field Sieve (NFS) to compute discrete logarithms in medium characteristic finite fields. We consider algorithms that combine two ideas, namely the Multiple variant of the Number Field Sieve (MNFS) taking advantage of a large number of number fields in the sieving phase, and two recent polynomial selections for the classical Number Field Sieve...
متن کاملInterference-Aware and Cluster Based Multicast Routing in Multi-Radio Multi-Channel Wireless Mesh Networks
Multicast routing is one of the most important services in Multi Radio Multi Channel (MRMC) Wireless Mesh Networks (WMN). Multicast routing performance in WMNs could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. In this paper we want to address the multicast routing problem for a given channel assignment in WMNs. The channels...
متن کاملUsing multicast to pre-load jobs on the ParPar cluster
The ParPar system is a high-performance cluster environment supporting a multiuser parallel workload. Its design follows a master-nodes structure, where the master controls all aspects of system activity using a dedicated control network. As nearly all control messages are multicast to a set of nodes, we implemented a reliable multicast protocol for this network based on UDP. This was then used...
متن کاملTower Number Field Sieve Variant of a Recent Polynomial Selection Method
At Asiacrypt 2015, Barbulescu et al. performed a thorough analysis of the tower number field sieve (TNFS) variant of the number field sieve algorithm. More recently, Kim and Barbulescu combined the TNFS variant with several polynomial selection methods including the Generalised Joux-Lercier method and the Conjugation method proposed by Barbulescu et al. at Eurocrypt 2015. Sarkar and Singh (Euro...
