Generalized file system dependencies

Christopher Frost, Mike Mammarella, Eddie Kohler, Andrew de los Reyes, Shant Hovsepian, Andrew Matsuoka, Lei Zhang
2007 Proceedings of twenty-first ACM SIGOPS symposium on Operating systems principles - SOSP '07  
A patch-based file system implementation expresses dependencies among writes, leaving lower system layers to determine write orders that satisfy those dependencies.  ...  We present a general abstraction, the patch, that makes write-before relationships explicit and file system agnostic.  ...  In particular, Steve VanDeBogart provided extensive help with Linux kernel details, memory semantics, and drafts.  ...

HF_IDS_Cam: Fast Video Capture with ImageJ for Real-Time Analysis

2018 Journal of Imaging  
Here we present an ImageJ plug-in: HF_IDS_Cam, which allows for video capture at very high speeds using IDS (Imaging Development Systems GmbH) cameras and image analysis software ImageJ.  ...  The software has been optimized for real time video analysis with ImageJ native function and other plug-ins and scripts. The plug-in was written in Java and requires ImageJ 1.47v or higher.  ...  We thank Imaging Development Systems (IDS France) for providing us the UI−3060CP camera. Conflicts of Interest: The authors declare no conflict of interest.  ...

A SURVEY ON CLOUD STORAGE – IMPACT OF STORAGE ON THE PERFORMANCE

Prapti Panigrahi .
2018 International Journal of Research in Engineering and Technology  
Storing and micromanaging data is an integral part of any application.  ...  Bandwidth usage can also be reduced, by sharing access-links instead of the complete files.  ...  Large Read/Write Architecture similar to Google File System would be a fitting choice in such a case. The whole system has been designed specially assuming large sequential read and write.  ...

NVthreads

Terry Ching-Hsiang Hsu, Helge Brügner, Indrajit Roy, Kimberly Keeton, Patrick Eugster
2017 Proceedings of the Twelfth European Conference on Computer Systems - EuroSys '17  
NVthreads' page level mechanisms result in good performance: applications that use NVthreads can be more than 2× faster than state-of-the-art systems that favor fine-grained tracking of writes.  ...  Non-volatile memory technologies, such as memristor and phase-change memory, will allow programs to persist data with regular memory instructions.  ...  Finegrained logging techniques micromanage NVM writes and introduce non-negligible slowdown.  ...

Advanced unit testing

Cyrille Artho, Armin Biere
2006 Proceedings of the 2006 international workshop on Automation of software test - AST '06  
Automated support for log files made it possible to track the internal state of objects, which is often much more expedient than writing test code.  ...  In the JNuke project, automated regression tests combined with coverage measurement ensured high code quality throughout the project.  ...  It allows testing of large data structures by writing their content to a log file and then manually inspecting it.  ...
