Abstract: Tracing of the interaction of third party processes on resources used by a program under trace is performed. A viral tag is associated with the program under trace. When the program “touches” a portion of memory, the memory manager associates the viral tag with the memory locations in this portion of memory. When subsequent processes “touch” the tagged memory locations, they acquire the viral tag and then spread it to other memory locations that these subsequent processes touch. The viral tag may be slightly modified so as to identify it as being based on the original viral tag but having been acquired by another process. Each time the viral tag is spread to another program, the viral tag may be slightly modified to indicate that the viral tag is now associated with another entity although is still associated with the original viral tag.

Abstract: In an embodiment of the invention an application provider may include “tracing elements” in a target software application. While working with the application the trace elements are detected and provide a “baseline trace” indicating proper application execution. The provider then supplies the application, which still includes the trace elements, and the baseline trace to a user. The user operates the application to produce a “real-time trace” based on the application still having trace elements that produce trace events. A comparator then compares the baseline and real-time traces. If the traces are within a pre-determined range of each other the user has a level of assurance the software is operating correctly. If the level of assurance is low, an embodiment may trigger a hardware interrupt or similar event to prevent further execution of software. Other embodiments are described herein.

In turn, a debug routine executes and retrieves the extracted data from the shared memory area.

Abstract: An approach is provided to trace a software program running in a multi-nodal complex computing environment. A trace request is sent from a requestor node to the nodes with the trace request associated with the software program and also associated with a transaction identifier. The software program is executed on the nodes. While the program is executing, trace data entries resulting from the execution of the software program are logged at the respective nodes with each trace data entry being associated with the transaction identifier. A log request is subsequently sent from the requestor node to the other nodes. The resulting trace data is then received by the requestor node from the target nodes and logged in a transaction based log. The transaction-based log is then provided to a user of the requestor node.

Abstract: The debugging of a program in a data parallel environment. A connection is established between a debugging module and a process of the data parallel environment. The connection causes the data parallel environment to notify the debugging module of certain events as they occur in the execution of the process. Upon notification of such an event, the process execution is paused, and the debugging module may query the data parallel environment for information regarding the process at the device independent virtual machine layer. Upon completion of this querying, the process may then resume execution. This may occur repeatedly if multiple events are encountered.

Abstract: Server management data describes observed operating condition of a pool of spare servers. Based on a demand forecast of a specific target system, a dynamic allocation period is determined as a period during which the target system needs additional server resources to handle an expected demand. Based on the dynamic allocation period and server management data, a set of allocation candidates are nominated from the spare server pool, by eliminating therefrom spare servers which are likely to fail during the dynamic allocation period. An appropriate allocation candidate is then selected for allocation to the target system, such that the selected candidate will satisfy a specified requirement during its allocation period.

In addition, the method determines that inter errors occur in the CPU if the interruption tag is equal to one, and determines that multi-bit errors occur in the memory if the interruption tag is greater than one.

The reset stub may also be invoked if errant direct memory access DMA operations are being performed by a hardware device. The reset stub may ensure that hardware immediately stops unfinished DMA from further transfer, and may be called by the user-mode driver module.

Abstract: A low privilege debug pipeline publisher advertises a debugging pipeline. Instead of having a client to which a debugger on the server has been attached interrogate the server for debugging information, the client requests information from the server. Control is returned to the server which can refuse to provide the requested information to the client. A debuggee server executes client code being debugged in an isolated context so that pausing the code at a breakpoint does not block the server. The server can apply transforms to compiled code to make the code cooperate with debugging services so that a privileged component to inspect the debuggee code is not needed.
