摘要： Method and apparatus for creating benchmark programs for the analysis of java virtual machine implementations are implemented. Java applications and applets are compiled into an intermediate code referred to as byte code. The Java byte code forms the machine code for the Java Virtual Machine. The Java Virtual Machine running on top of a hardware platform translates the byte code into native machine code for execution on the hardware platform on which the Java Virtual Machine is running. The performance of a Java Virtual Machine is improved by the use of a so-called "just in time" (JIT) compiler that translates commonly occurring sequences of bytes codes in the native instruction sequences which are then stored for later execution. Critical to the performance of the JIT is the ability of the JIT to optimally compile for the most commonly occurring sequences of byte codes. The method and apparatus for creating benchmark programs provides a means for performance measurements with respect to such sequences.

摘要： A method and system that reduces the length of time required to complete antivirus scans. An enhanced journal file system (JFS) includes an antivirus utility function, which utilizes a low level log of the JFS to store a history of transactions that occur since a previous scan operation. The log is immune from normal purge operations by the JFS and cannot be circumvented without driver level access. Thus, a virus that changes the timestamp on the file or otherwise attempts to hide its viral activity does not affect the log. When the antivirus scanning utility initiates an antivirus scan of the system, the antivirus scanning utility obtains the history since the last scan from the persistent log. The antivirus scanning utility “replays” the log and carries out the antivirus scan on all files, directories, etc. associated with any transactions that occurred since the last scan.

摘要： Methods, systems, and products are provided that display memory statistics for a keydrive that do not require the keydrive to be plugged into another device. Displaying memory statistics according to embodiments of the present invention include receiving a command resulting in a change to the memory usage of the keydrive, calculating memory statistics describing the current state of memory usage of the keydrive, storing the memory statistics in memory on the keydrive, and displaying the memory statistics on a display on the keydrive. Calculating memory statistics describing the current state of memory usage of the keydrive may be carried out by calculating a total memory usage of the keydrive. Calculating memory statistics describing the current state of memory usage of the keydrive may also be carried out by calculating a percent of total memory used.

摘要： A method and system that provides a pass through block device that is utilized to redirect all the writes bound to the system drive(s) to an overlay skin device. Reads are performed on overlay device contents and the overlay device contents take precedence over the contents of the base device. Applications of a particular theme may be installed on the overlay device. The overlay device is provided on a removable media and thus allows for creation of a set of exchangeable skins. Nested overlays are utilized to create separation of the OS data, application data, and user data. Switchable user skins enable writes into overlays and allow a user to create operating environments which can be utilized to change the use of a computer system. Since the overlays are provided on a removable media, the user only needs to substitute the overlay to switch the user's operating environment.

摘要： A method, system, apparatus, and computer program product is presented for processing instructions. A processor is able to receive multiple types of interruptions while executing instructions, such as aborts, faults, interrupts, and traps. A set of processor fields are used to indicate whether or not one or more trap modes are active, such as a single-step trap mode or a taken-branch trap mode. The activity of a trap mode is conditioned, i.e., restricted, modified, or qualified, with a trap mode conditioning field that indicates whether or not the trap mode should remain active during interruption processing. The use of a trap mode conditioning field allows an interruption handler to run at full speed without being interrupted by the trap mode, yet the trap mode is preserved so that other processing, such as instruction tracing, may continue after interruption processing.

摘要： A method and system that enables anti-virus scanning protection of a computer system by placing all changes/updates/installations on a system-wide skin and performing the scan and clean operation on the skin before allowing the components to be merged with those of the base system. A system-wide skin is provided, which covers the entire base system of a computer. A complete scan and clean operation is first performed on the base system before a first skin is placed over the base system. Then any new applications, files, or data are installed on the skin, which overlays the entire base system, such that no updates are actually made to the base system while the system-wide skin is present. All subsequent scan and clean operations are conducted only on the system-wide skin, thus significantly reducing the time for completing such operations. Multiple skins may be provided and clean data merged from one skin to another.
