Networks of Workstations (NOW) have become an attractive alternative platform for high performance computing. Due to the commodity nature of workstations and interconnects and due to the multiplicity of vendors and platforms, the NOW environments are being gradually redefined as Heterogeneous Networks of Workstations (HNOW) environments. This paper presents(More)
Storage systems are the next frontier for providing protection against intrusion. Since storage systems see changes to persistent data, several types of intrusions can be detected by storage systems. Intrusion detection (ID) techniques can be deployed in various storage systems. In this paper, we study how intrusions can be detected at the block storage(More)
Recent advances in solid state technology have led to the introduction of solid state drives (SSDs). Today's SSDs store data persistently using NAND flash memory and support good random IO performance. Current work in exploiting flash in database systems has primarily focused on using its random IO capability for second level bufferpools below main memory.(More)
Networks of Workstations (NOW) have become an attractive alternative platform for high performance computing. Due to the commodity nature of workstations and interconnects and due to the multiplicity of vendors and platforms, the NOW environments are being gradually redefined as Heterogeneous Networks of Workstations (HNOW). Having an accurate model for the(More)
Sharing resources such as caches and main memory bandwidth in multi-core systems requires a more sophisticated scheduling scheme which takes the characteristics of such systems into account. PAM is a lowoverhead, user-level meta-scheduler which does not require any hardware or software changes. In particular, it operates by detecting resource congestions(More)
The IBM RS/6000 SP system is one of the most costeffective commercially available high performance machines. IBM RS/6000 SP systems support the Message Passing Interface standard (MPI) and LAPI. LAPI is a low level, reliable and efficient one sided communication API library, implemented on IBM RS/6000 SP systems. This paper explains how the high performance(More)
ions provide new tools to enable the richer networking functionalities demanded by recent industry trends including dynamic virtual server workloads, multi-tenant cloud computing, and warehouse-scale data centers. Existing standards and abstractions have proven inadequate for delivering this functionality Bat scale[; for example, 12-bit virtual local area(More)
Networks of Workstations (NOW) have become an attractive alternative platform for high performance computing. Due to the commodity nature of workstations and interconnects, the NOW environments are being gradually redeened as Heterogeneous Networks of Workstations (HNOW) environments.
