Title
Report on workshop on operating systems support for next generation large scale NVRAM (NVRAMOS 2009)
Abstract
1. MOTIVATIONS NAND Flash memory solid state disk (hereafter SSD) technology is advancing rapidly in capacity and speed. Also, we envision that byte-addressable NVRAM devices, which is being thought as the future replacement of Flash memory technology will be commercially viable for storage within the next 3-7 years. Modern computer system takes hierarchical organization. It consists of CPU, Main Memory and Storage. This hierarchical organization is natural outcome of economic concern. Modern Operating System is designed to effectively exploit the physical characteristics of the device in each system hierarchy. Process management, memory management, and storage management subsystems are all designed to fill the gaps (speed and space) among the layers in different hierarchies while maximizing cost performance ratio. Current operating system paradigm draws clear line between memory and storage and handles them in very different way. Large scale byte-addressable NVRAM combines the physical characteristics of main memory with the non- volatility of storage, presenting new challenges for system designers. From the DBMS and Operating System's point of view, the advancement of this device calls for a reconsideration of legacy operating system architectures that have been designed based upon the notion of system hierarchy: CPU, memory and storage. NVRAMOS Workshop (Workshop on Systems Support for large Scale NVRAM) is biannual event which invites leading experts from academia as well as industry in the area of large scale NVRAM, Flash Storage, Storage Class Memory, NVRAM device technology and related areas. The workshop specifically focuses on Operating Systems aspect of exploiting new semiconductor technology (FLASH, PRAM, MRAM, FRAM, Solid Electrolyte) as storage device or memory/storage device. The primary goal of this workshop is to form a community in this field and provide a forum where the experts in this area can put forth their vision, share views, exchange ideas and have intensive discussions on the technical challenges we may face (or are facing already) in the next several years. The first NVRAMOS workshop was held in Nov. 2007. NVRAMOS workshop now successfully positions itself as prime forum which achieves the original goal. NVRAMOS workshop has been two day event and has been allocating extensive time slot for each presentation so that speaker and the workshop participants can have interactive and intense technical discussion about the talk theme in in-depth manner.
