Aug 1, 2002

Appl. No.:

10/210438

Inventors:

Steven E. Krueger - Raleigh NC, US

Assignee:

SAS Institute Inc. - Cary NC

International Classification:

G06F 9/44

US Classification:

Abstract:

A computer-implemented system and method for handling run-time exceptions. Source code is provided as input to a compiler. The source code includes an exception branching statement and an exception catching statement. The compiler generates machine code from the source code. During execution of the machine code, an exception occurs and execution branches to the exception catching statement in accordance with the exception branching statement.

Steven E. Krueger - Raleigh NC, US

Assignee:

SAS Institute Inc. - Cary NC

International Classification:

G06F 9/44

US Classification:

717106, 717107, 717108, 717109

Abstract:

A computer-implemented system and method for generating code. The system and method receive source code that includes a higher order computer language statement. Machine code is generated from the received source code. The generated machine code is placed directly into volatile memory for access by a computer program.

Appl. No.:

11/555147

Inventors:

Steven Krueger - Raleigh NC, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L 12/26

US Classification:

370232, 709232, 709233, 3702301, 370231

Abstract:

In one embodiment, a device includes: a transceiver operable to transmit packets to and receive packets from a modem; and a logic engine configured to transmit first packets at a rate through an upstream path for a modem to an Internet node such that no throttling is triggered in the modem, the logic engine being further configured to transmit second packets through the upstream path for the modem to the Internet node at a rate sufficient to trigger throttling in the modem if the modem implements throttling, the logic engine being further configured to compare an average transmission time for first packets to an average transmission time for the second packets to determine whether the modem implements throttling.

Inventors:

- Cary NC, US
Gordon Lyle Keener - Raleigh NC, US
Steven E. Krueger - Raleigh NC, US

Assignee:

SAS Institute Inc. - Cary NC

International Classification:

G06F 17/30
G06F 9/50

Abstract:

An apparatus including a processor to index data records within a data cell, wherein for each data record, the processor retrieves data values from first and second data fields; determines whether the first and second data fields store unique data values; in response to the first data field storing a unique data value, adds an identifier of the data record to a first unique values index, in response to the second data field storing a unique data value, adds the identifier to a second unique values index, wherein identifiers of data records within the unique values indexes are ordered based on corresponding unique data values; and generates an indication of ranges of data values of the first and second data fields to enable a determination of whether a data value specified in search criteria is present within at least the data cell.

G06F 9/50

Abstract:

An apparatus includes a processor component caused to: retrieve metadata of organization of data within a data set, and map data of organization of data blocks within a data file; receive indications of which node devices are available to perform a processing task with a data set portion; and in response to the data set including partitioned data, compare the quantities of available node devices and of the node devices last involved in storing the data set. In response to a match, for each map data map entry: retrieve a hashed identifier for a data sub-block, and a size for each of the data sub-blocks within the corresponding data block; divide the hashed identifier by the quantity of available node devices; compare the modulo value to a designation assigned to each of the available node devices; and provide a pointer to the available node device assigned the matching designation.

Assignee:

SAS Institute Inc. - Cary NC

International Classification:

G06F 9/48

Abstract:

An apparatus includes a processor and a storage storing instructions causing the processor to determine whether an analysis routine is multi-threaded and calls a library function of a non-threadsafe library, and if so, causes the processor to: instantiate an analysis process for executing the analysis routine on multiple threads; instantiate an instance of the library for execution within a isolated library process; instantiate another instance of the library for execution within another isolated library process; retrieve library metadata providing a function prototype of the library function; employ the function prototype to generate an instance of a bridge routine to enable a call from the analysis routine on a first thread to the library function; employ the function prototype to generate another instance of the bridge routine to enable a call from the analysis routine on a second thread to the library function; and begin execution of the analysis routine.
