US Patent:

20100180002, Jul 15, 2010
Filed:

Mar 24, 2010
Appl. No.:

12/730280
Inventors:

Imran Ahmed - Arlington VA, US
John J. Auvenshine - Tucson AZ, US
Justin Blackburn - Surprise AZ, US
Assignee:

INTERNATIONAL BUSINESS MACHINES CORPORATION - Armonk NY
International Classification:

G06F 15/16
G06F 15/173
US Classification:

709207, 709224, 709226
Abstract:

A system for maintaining a high availability data transmission and processing environment. The system includes a network of clusters and a control server. Each cluster of the network includes at least two identical servers. Each cluster of the network is directly connected to at least one other cluster of the network. Each pair of clusters directly connected to each other is characterized by each server in a first cluster of the pair of clusters being directly connected to at least one server in a second cluster of the pair of clusters via a communication link. The control server is configured to monitor an operational status of the communication link (i.e., the communication link is operational or non-operational). The control server is directly linked to at least one server in each cluster via a communication channel between the control server and the at least one server.

US Patent:

20090100247, Apr 16, 2009
Filed:

Oct 12, 2007
Appl. No.:

11/871659
Inventors:

William C. Moyer - Dripping Springs TX, US
Imran Ahmed - Austin TX, US
Dan E. Tamir - Austin TX, US
International Classification:

G06F 9/30
G06F 9/02
US Classification:

712 4, 712E09002, 712E09024
Abstract:

A processor in a data processing system executes a permutation instruction which identifies a first source register, at least one other source register, and a destination register. The first source register stores at least one in-range index value for the at least one other source register and at least one out-of-range index value for the at least one other source register. The at least one other source register stores a plurality of vector element values, wherein each in-range index value indicates which vector element value of the at least one other source register is to be stored into a corresponding vector element of the destination register. Each out-of-range index value is used to indicate which one of at least two predetermined constant values is to be stored into a corresponding vector element of the destination register. Partial table lookups using a permutation instruction shortens the time required to retrieve data.

US Patent:

20070239968, Oct 11, 2007
Filed:

Apr 5, 2006
Appl. No.:

11/278725
Inventors:

William Moyer - Dripping Springs TX, US
Imran Ahmed - Austin TX, US
Dan Tamir - Austin TX, US
International Classification:

G06F 9/44
US Classification:

712221000
Abstract:

A method for operating a data processing system is provided. The method includes providing a first operand stored in a first register, providing a second operand stored in the register, providing a third operand stored in the register. The method further includes executing a first instruction, where executing the first instruction comprises: (1) retrieving the first operand, the second operand, and the third operand from the first register; (2) performing an operation using the first operand, the second operand, and the third operand to generate a bit exact result.

Justin Blackburn - Surprise AZ, US
International Classification:

G06F015/173
US Classification:

709223000
Abstract:

A method for maintaining a high availability data transmission and processing environment. A network of clusters is provided. Each cluster of the network includes at least two identical servers. Each cluster of the network is directly connected to at least one other cluster of the network. Each pair of clusters directly connected to each other is characterized by each server in a first cluster of the pair of clusters being directly connected to at least one server in a second cluster of the pair of clusters via a communication link. Provided is a control server adapted to monitor an operational status of the communication link (i.e., the communication link is operational or non-operational). The control server is directly linked to at least one server in each cluster via a communication channel between the control server and the at least one server.
