  • 24 Bringing Order to Chaos: Barrier-Enabled I/O Stack for Flash Storage
    Bringing Order to Chaos: Barrier-Enabled I/O Stack for Flash Storage YOUJIP WON and JOONTAEK OH, Hanyang University, Korea JAEMIN JUNG, Texas A&M University, USA GYEONGYEOL CHOI and SEONGBAE SON, Hanyang University, Korea JOOYOUNG HWANG and SANGYEUN CHO, Samsung Electronics, Korea This work is dedicated to eliminating the overhead required for guaranteeing the storage order in the modern IO stack. The existing block device adopts a prohibitively expensive approach in ensuring the storage order among write requests: interleaving the write requests with Transfer-and-Flush. For exploiting the cache bar- rier command for flash storage, we overhaul the IO scheduler, the dispatch module, and the filesystem sothat these layers are orchestrated to preserve the ordering condition imposed by the application with which the associated data blocks are made durable. The key ingredients of Barrier-Enabled IO stack are Epoch-based IO scheduling, Order-Preserving Dispatch,andDual-Mode Journaling. Barrier-enabled IO stack can control the storage order without Transfer-and-Flush overhead. We implement the barrier-enabled IO stack in server as well as in mobile platforms. SQLite performance increases by 270% and 75%, in server and in smartphone, respectively. In a server storage, BarrierFS brings as much as by 43× andby73× performance gain in MySQL and SQLite, respectively, against EXT4 via relaxing the durability of a transaction. CCS Concepts: • Software and its engineering → File systems management; Additional Key Words and Phrases: Filesystem, storage, block device, linux ACM Reference format: Youjip Won, Joontaek Oh, Jaemin Jung, Gyeongyeol Choi, Seongbae Son, Jooyoung Hwang, and Sangyeun Cho. 2018.

  • Open Source Software and Goverment Policy in South
    OPEN SOURCE SOFTWARE AND GOVERNMENT POLICY IN SOUTH AFRICA Minnaar Pieters Thesis submitted in fulfilment of the requirements for the degree of Magister Artium (Socio‐Informatics) © Stellenbosch University 2008 Supervisor: Prof Johann Kinghorn March 2008 Stellenbosch University http://scholar.sun.ac.za Declaration I, the undersigned, hereby declare that the work contained in this thesis is my own original work and that I have not previously in its entirety, or in part, at any university for a degree. Signature: ………………………………. Date: ………………………………. ii Stellenbosch University http://scholar.sun.ac.za Summary Open-source software is not something new; however, it has come into the spotlight in the last few years, mostly due to hyped initial cost savings of the Linux operating system. Consumers and businesses were made aware of shortcomings in the traditional proprietary software model and this has in turn created a surge in popularity of open-source. The migration to open-source requires efficient research of options available and thorough analysis of the migratory process through all levels of the organization. Initial independent cost analysis has not been conclusive, with unreliable, skewed results and below average performance due to poor implementation. The focus of this study is whether open-source software is a suitable alternative to current proprietary software packages utilized by the government sector. The government sector offers unique challenges to which open-source software can be ideally suited. These include high initial costs of hardware and proprietary software, vendor lock-in, file format “future proofing” and the need for high security. Open-source software has addressed most of these issues admirably, but requires proper implementation.

Conventional supe rcomputers achieve their speed using extremely optimized hardware that operates at very high speed. Then, how do the clusters out-perform them? Simple, they cheat. While the supercomputer is optimized in hardware, the cluster is so in software. The cluster breaks down a problem in a special way so that it can distribute all the little pieces to its constituents. That way the overall problem gets solved very efficiently. - A Brief Introduction To Commodity Clustering Ryan Kaulakis IMSc -Jan 2005 [email protected] What is MOSIX? ● MOSIX is a software solution to minimise OS level bottlenecks - originally designed to improve performance of MPI and PVM on cluster systems http://www.mosix.org Not open source Free for personal and academic use IMSc -Jan 2005 [email protected] MOSIX More Technically speaking: ● MOSIX is a Single System Image (SSI) cluster that allows Automated Load Balancing across nodes through preemptive process migrations.
