Pascal Tannhof - Fontainebleau, FR

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F012/00

US Classification:

711/217000, 711/171000

Abstract:

A method and apparatus for compressing a reference pattern (RP) with repeated substrings by encoding produce compressed reference patterns (CRPs) with reduce storage requirements. Operation codes and a flag are stored with the CRPs. During comparison of reference elements of the CRP to input elements (IEs) of an input pattern (IP), the operation codes are read and the reference pattern is decoded allowing all reference elements including those of the repeated substrings to be compared to IEs in the IP to determine if the RP appears within the IP.

Assignee:

INTERNATIONAL BUSINESS MACHINES CORPORATION - Armonk NY

International Classification:

G06F 17/30

US Classification:

707687, 707E17005

Abstract:

An apparatus for dynamically redirecting a file descriptor includes an identification module, a disassociation module, and an association module. The identification module identifies a first executing process using a second executing process. The first executing process may include a file descriptor and the first executing process may be independent of the second executing process. The disassociation module disassociates the file descriptor from a first data stream using the second executing process without involvement of the first executing process. The association module associates the file descriptor with a second data stream using the second executing process without involvement of the first executing process in response to the disassociation module disassociating the file descriptor from the first data stream.
