DataBlitz’ is a main-memory storage management toolkit that supports the development of highperformance and fault-resilient applications requiring concurrent access to shared data. By combining transactions, data organization, and fault-resilience with direct access to data, DataBlitz bridges the gap between the speed of data structures in shared memory and the safety and convenience of a tradi...

Many modern applications rely on high-performance processing of spatial data. Examples include location-based services, games, virtual worlds, and scientific simulations such as molecular dynamics and behavioral simulations. These applications deal with large numbers of moving objects that continuously sense their environment, and their data access can often be abstracted as a repeated spatial ...

Update technique is an important issue related to database recovery. In a main memory database environment, transaction execution can be processed without any I/O, and all I/O operations involved are for recovery purposes. The efficiency of update techniques therefore has an important impact on the performance of main memory database systems. In this paper, we compared the techniques of immedia...

M 2 RTSS is a main-memory storage system, which has been under recent development at Seoul National University as a vehicle for high-performance and real-time database application research. To deal with requirements from various applications, M 2 RTSS architecture is designed to have extensibility in many aspects of storage system functionality. One crucial aspect of such extensibility is that ...

Most applications running on supercomputers achieve only a fraction of a system’s peak performance. It has been demonstrated that co-scheduling applications improves overall system utilization. In this case, however, applications being co-scheduled need to fulfill certain criteria such that mutual slowdown is kept at a minimum. In this paper we present a set of libraries and a first HPC schedul...

The growth in variety and volume of OLTP (Online Transaction Processing) applications poses a challenge to OLTP systems to meet performance and cost demands in the existing hardware landscape. These applications are highly interactive (latency sensitive) and require update consistency. They target commodity hardware for deployment and demand scalability in throughput with increasing clients and...

We present design and implementation techniques for storage management in main memory database systems. ALTIBASE is the relational main memory DBMS that enables us to develop the high performance and fault tolerant applications requiring predictable response time and high availability. It provides the short and predictable execution time and the storage for the various type of enormous data as ...

A database system optimized for in-memory storage can support much higher transaction rates than current systems. However, standard concurrency control methods used today do not scale to the high transaction rates achievable by such systems. In this paper we introduce two efficient concurrency control methods specifically designed for main-memory databases. Both use multiversioning to isolate r...
