According to various embodiments, a heating system for heating a building and/or for preparing hot water is provided. The heating system can comprise a heat distributing device; and a computer, which is coupled to the heat distributing device in such a way that the heat produced by the computer is distributed in the building by means of the heat distributing device; wherein the computer is designed in such a way that the computer produces a message for a computing load distribution computer, wherein the message contains a piece of information about the heat demand of the heating system and/or of the building.

In one embodiment, a method is provided for data processing in order to provide a value for determining whether an error has occurred in the execution of a program. The method may include: determining a numerical value on the basis of a plurality of reference numbers determined by a checking circuit outside the program; determining a signature of at least one instruction of the program by means of an arithmetic code; updating a cumulative value on the basis of the numerical value and the signature; and transferring the updated cumulative value to the checking circuit in order to determine whether an error has occurred in the execution of the program, on the basis of the plurality of reference numbers and the cumulative value.

Method for providing a value for determining whether an error has occurred in the execution of a program

A topology discovery process is used to discover all of the links in an ad hoc network and thereby ascertain the topology of the entire network. One of the nodes of the network, referred to as the coordinator, receives the topology information which can then be used to, for example, distribute a routing table to each other node of the network. The process has a Diffusion phase in which a k-resilient mesh, k&#x3e;1, is created by propagating a topology request message through the network. Through this process, the nodes obtain information from which they are able to discern their local neighbor information. In a subsequent, Gathering phase, the local neighbor information is reported upstream from a node to its parents in the mesh and thence to the parents' parents and so forth back to the coordinator. The robustness of the Diffusion phase is enhanced by allowing a node to have more than one parent as well as by a number of techniques, including use of a so-called diffusion acknowledgement message. The robustness of the Gathering phase is enhanced by a number of techniques including the use of timeouts that ensure that a node will report its neighbor information upstream even if it never receives neighbor information from one or more downstream neighbors and the use of a panic mode that enhances the probability that a node will get its neighbor information, and its descendents' neighbor information, reported upstream even if that node has lost connectivity with all of its parents.

Adaptive topology discovery in communication networks

The present embodiments provide methods for detecting errors and vulnerabilities in software without access to its source code. The method entails extracting functions from dynamically linked applications, determining error return codes and error numbers for the extracted functions, and forming a wrapper using the extracted functions. The wrapper is used to intercept some of the function calls, wherein the intercepted functions are manipulated to fail. The embodiments further relate to an article of manufacture to detect errors. The article of manufacture utilizes an extraction module to extract functions from dynamically linked applications, software to compile error return codes and error numbers for functions, and a wrapper module to form a wrapper with the extracted functions.

Method for detecting software errors and vulnerabilities

A method includes a step of executing a software function using a set of test arguments and obtaining a result corresponding to each of the set of test arguments, each result indicating one of a set of robust and non-robust results, a subset of test arguments corresponding to robust results. The method further includes defining a set of arguments based on the results and the set of test arguments, the set of arguments including the subset of test arguments. Thereafter, arguments of subsequent calls to the software function may thereafter be examined to determine whether they fall within the set of arguments.

Robust software library wrapper method and apparatus

A method and apparatus for detecting a heap smashing condition. A call to a library function, such as a request to write a data block to the heap section of a memory, is intercepted from a program being executed. In an embodiment, a fault-containment wrapper module determines whether performing the write request would smash the heap. If it would smash the heap, an error handling procedure is executed instead of writing the data block. If it would not smash the heap, the fault-containment wrapper module causes the data block to be written to the memory as requested.
