Abstract: Techniques for modeling a data center are provided. In one aspect, a method for modeling a data center is provided. The method comprises the following steps. Spatially dense three-dimensional thermal distribution and air flow measurements made in the data center using a mobile off-line surveying system are obtained. A temperature and air flow model for the data center is created using the spatially dense three-dimensional thermal distribution and air flow measurements. The temperature and air flow model is used to make thermal distribution and air flow predictions of the data center. The thermal distribution and air flow predictions are compared with the thermal distribution and air flow measurements made using the mobile off-line surveying system to produce a validated model for the data center.

Abstract: A method and apparatus is described for parallel debugging on the data nodes of a parallel computer system. A data template associated with the debugger can be used as a reference to the common data on the nodes. The application or data contained on the compute nodes diverges from the data template at the service node during the course of program execution, so that pieces of the data are different at each of the nodes at some time of interest. For debugging, the compute nodes search their own memory image for checksum matches with the template and produces new data blocks with checksums that didn't exist in the data template, and a template of references to the original data blocks in the template. Examples herein include an application of the rsync protocol, compression and network broadcast to improve debugging in a massively parallel computer environment.

A second signal-filtering subsystem substantially filters out the signals in the first frequency band from the second transceiver subsystem.

Abstract: Equivalent oxide thickness (EOT) scaled high k/metal gate stacks are provided in which the capacitance bottleneck of the interfacial layer is substantially eliminated, with minimal compromise on the mobility of carriers in the channel of the device. In one embodiment, the aforementioned EOT scaled high k/metal gate stacks are achieved by increasing the dielectric constant of the interfacial layer to a value that is greater than the originally formed interfacial layer, i.e., the interfacial layer prior to diffusion of a high k material dopant element therein. In another embodiment, the aforementioned scaled high k/metal gate stacks are achieved by eliminating the interfacial layer from the structure. In yet another embodiment, the aforementioned high k/metal gate stacks are achieved by both increasing the dielectric constant of the interfacial layer and reducing/eliminating the interfacial layer.

The manageable component engine queries one or more data sources, and accesses data required for creating a manageable component object instance. One or more manageable component objects are registered in a manageable component repository. The manageable component bridge model is created and displayed via a graphical user interface.

Abstract: A computer implemented method and program product for configuring and prioritizing local network print requests. In one embodiment, a printer shared on multiple networks is configured to a set of parameters defined by an administrator for prioritizing the print requests received from users on a local network. A first print request is received from a first user on a remote network. The first print request originating from the first user on a remote network is printed. A second print request is received from a second user on a local network. A determination is made whether a match to the set of parameters is present. In response to determining a match to the set of parameters is present, the first print request is interrupted in order to print the second print request on the printer. The first print request from the remote network is resumed once the second print request from the local network is completely printed.

Abstract: A method of estimating a transit demand graph includes collecting conditional information that includes at least one condition that when satisfied converts at least one non-rider into a rider, generating a non-rider transit demand graph by satisfying one of the conditions, and generating a normalized transit demand graph from the non-rider transit demand graph and a rider transit demand graph. The riders use public transit and the non-riders do not use public transit. The non-rider transit demand graph shows the demand of the non-riders for a public transit route. The rider transit demand graph shows the demand of riders for the same public transit route.

Abstract: A system for blending synchronous and asynchronous computer communication applications that determines when a user of a synchronous communication application, such as an instant messaging application, attempts to send a message to another user that is unavailable for synchronous communications, and that forwards the message from the synchronous communication application to an asynchronous communication application for delivery. The forwarded message may be an email message, and the system may operate to determine a destination electronic mail address of the destination user for inclusion in the forwarded message, and include an indication in the forwarded message that it has been forwarded from the synchronous communication application. This indication enables the asynchronous communication application to perform special processing when the receiving user retrieves the forwarded message from the asynchronous communication application.

Abstract: A method and system for recognizing a character affected by a noise or an obstruction is disclosed. After receiving an image with characters, a character being affected by a noise or an obstruction is determined. Then, areas in the character where the noise or obstruction affected are precisely located. Templates representing every possible character in the image are updated by removing equivalent areas to the areas in the character being affected by the noise or obstruction. Then, the character is classified in a template among the updated templates by finding the template having the highest number of matching pixels with the character.

Abstract: An on-demand virtual drive from dedicated storage on a plurality of partners in a peer-to-peer network uses an agent installed on each of the partners. The agent has a contributing program and a requesting program. The contributing program creates a first storage unit and a second storage unit, formatting the second storage unit so that it is not visible to the operating system of the partner and transmitting the size of the second storage unit to the other partners. The requesting partner creates a virtual drive using space on selected partner's second drives, and directs data blocks in and out of the virtual drive. A rules engine incorporating RAID algorithms governs the selection of the partners and allocation of available space.
