This section provides solutions to some performance problems, and describes configuration best practices.   Important: If you are running CDH over 10Gbps Ethernet, improperly set network configuration or improperly applied NIC firmware or drivers can…

1.Performance Software performance is one of software quality attributes,  it  equal to efficiency which define in latest ISO 9126 standard : Efficiency This characteristic is concerned with the system resources used when providing the required funct…

BACKGROUND OF THE INVENTION The present invention relates to a storage system offering large capacitance, high performance, and high availability through a hierarchical construction of RAID and a method for controlling the storage system; and more pa…

BACKGROUND INFORMATION In a typical data processing environment, data may be transmitted in multiple packets, e.g., words, from one element, e.g., cache, to another element, e.g., processor, over a bus, e.g., parallel bus. A hamming distance may refe…

BACKGROUND As processing resources have increased, demands to run multiple software programs and operating systems on a single microprocessor have also increased. To meet these demands virtual environments have been developed to allocate a single com…
