A user interface is described that displays a hierarchical structure of a computer system. The hierarchical structure of a system configuration for a computer system is formed by the upward and downward connections between various levels of symbolic and real hardware components. In particular, the user interface displays a graphical model of the hierarchical tree-like structure of the configuration in a single computer window. An individual hardware component may have multiple upward connections...

An embodiment of the present invention is a method for generating a simulated processor load on a system of CPU's, and introducing a controlled workload into the system that is spread evenly across the available CPU resources and may be arranged to consume a precise, controllable portion of the resources.

Bypassing loading of memory in accessing large data objects in a relational database. A relational database may include a plurality of first type data items and associated second type data items. In response to an update-type access request, requester memory is bypassed in writing to the relational database a second type data item referenced by a file location specified in the update-type request. In response to retrieve-type request, requester memory is bypassed in reading from the relational d...

Variable compensation for part to part skew of components in a substrate-mounted circuit is described. The variability may be provided through a computer software program acting on a programmable delay buffer such that compensation for a skewed signal may be continuously checked against a reference signal or through other methods. The skewed signal may be delayed until the signal matches, within a predetermined margin of error, the reference.

A system, apparatus and method enabling common memory pool tests to be conducted in a multiprocessing system by using substantially the same system components that are used during a normal mode of operation. Under normal mode of operation, a data cache interface facilitates data transfer between processors of a multiprocessor system and the common memory pool. In test mode of operation, an integrated data cache exerciser assumes control of the data cache interface to facilitate test data write a...

Various approaches for updating system monitoring policy parameters. In one approach, updates to the monitoring policy parameters are transmitted to an event server via an event report. The event server transmits the event report to a subcomponent manager executing on the monitored system. The subcomponent manager determines to which of a plurality of monitoring subcomponents the update is to be applied. The subcomponent manager then suspends the execution thread of the monitoring subcomponents,...

Code coverage questions are addressed by a code coverage method that instruments an electronic module source design file with coverage probes and gives hierarchical names to the probes, then provides therefrom an instrumented gate level netlist. The instrumented netlist is run on a hardware emulator, executing reset trigger scripts to reset the branch and statement probes, and then a fully initialized design is driven in emulation on a simulated testbench from which the probe values are retrieve...

Methods and apparatus for providing electromagnetic interference (EMI) shielding for a module receiving area within a computer server housing configured to receive an input/output (IO) module are disclosed. The module receiving area is covered with a door. EMI shielding is provided by transitioning the door from a closed position to an open position in response to a force applied by the IO module, maintaining contact between the IO module and the door while the door is open to provide EMI shield...

A method for transmitting information in a KStore system having a KStore, an application programming interface and an application layer wherein the information is transmitted between the KStore and the application layer includes transmitting the information between the KStore and the application layer by way of the application programming interface. The KStore is constrained by way of the application programming interface with at least one constraint to provide at least one selected K path. The ...

An emulation system that provides the functionality of an emulated computer on a host computer pre-processes the object code file to be emulated to reduce the run-time overhead due to parsing the object code. The emulator uses pre-programmed functions that model each instruction of the emulated computer. An object code file is pre-parsed to generate a translated file which includes a sequence of function calls corresponding to the sequence of instructions in the code file. The translated file is...
