20120011491EFFICIENT RECORDING AND REPLAYING OF THE EXECUTION PATH OF A COMPUTER PROGRAM - To monitor the execution path of executable code, only non-deterministic jump instructions of the executable code are instrumented by replacing them with respective recording instructions that record the results of executions of the non-deterministic jump instructions and then emulate those executions, thereby providing instrumented code, and the instrumented code is executed. Preferably, the recording instructions are one byte long and invoke an interrupt service routine that does the recording and the emulating. Optionally, selected instructions of the executable code are replaced with trigger instructions for turning the recording on and off. Preferably, after the instrumented code is executed, the addresses of the instrumented instructions and the results of their executions are played back either forward or backward. Optionally, the instrumented code is executed a second time and the results of the executions of the instrumented instructions in the two executions of the instrumented code are compared.01-12-2012

20080301371Memory Cache Control Arrangement and a Method of Performing a Coherency Operation Therefor - A memory cache control arrangement for performing a coherency operation on a memory cache comprises a receive processor for receiving an address group indication for an address group comprising a plurality of addresses associated with a main memory. The address group indication may indicate a task identity and an address range corresponding to a memory block of the main memory. A control unit processes each line of a group of cache lines sequentially. Specifically it is determined if each cache line is associated with an address of the address group by evaluating a match criterion. If the match criterion is met, a coherency operation is performed on the cache line. If a conflict exists between the coherency operation and another memory operation the coherency means inhibits the coherency operation. The invention allows a reduced duration of a cache coherency operation. The duration is further independent of the size of the main memory address space covered by the coherency operation.12-04-2008

20090006594Method and system for remote manageability of networked computers - A method and system may allow a management server in a first network to communicate via a mediator server with a management module of a computing system in a second network. The mediator server may establish a communication connection to the management module and the data transferred from the management server to the management module may be associated with the communication connection.01-01-2009
20090070467Enabling access to remote entities in access controlled networks - In network access control networks, it may be difficult to provide certain remote accesses such as remote boot or remote storage access. An available network connection established through chipset firmware (e.g. active management technology (AMT)) may be utilized to establish a connection and to enable the remote access. Then as soon the completion of the activity is detected, such as remote booting, then the connection may be immediately terminated to prevent access by improper agents.03-12-2009
20090083844Synchronizing between host and management co-processor for network access control - In network access controlled networks, it is desirable to prevent access to the network by any non-authenticated entities. Access control may be established through a trusted agent that, in some embodiments, may be implemented with a management co-processor. In some cases, active management technology may establish a connection while a host is inactive. Then, after the host becomes active, the host can attempt to use the management co-processor connection without obtaining the necessary authentications. This may be prevented, in some embodiments, by scanning for an active host and, if such an active host is found, blocking the host from using a layer 2 authentication channel unless the host is properly authenticated and has a proper Internet Protocol address.03-26-2009
20090165099PROVISIONING ACTIVE MANAGEMENT TECHNOLOGY (AMT) IN COMPUTER SYSTEMS - Active management technology (AMT) may be provisioned in a client device automatically, which may provide a secure connection between the provisioning server and the client device. The client device comprising the active management technology may support zero-touch provisioning and one-touch provisioning.06-25-2009
