摘要： An apparatus is provided for sampling instructions in a processor pipeline of a computer system. The pipeline has a plurality of processing stages. Instructions are fetched into a first stage of the pipeline. A subset of the fetched instructions are identified as selected instructions. Event, latency, and state information of the system is sampled while any of the selected instructions are in any stage of the pipeline. Software is informed whenever any of the selected instructions leaves the pipeline to read the event and latency information.

摘要： A method is provided for estimating execution rates of program executions paths. The method samples path-identifying state information of selected instructions while executing the program in a processor. A control flow graph of the program is supplied, the control flow graph includes a plurality of path segments. The control flow graph is analyzed using the path-identifying state information to identify a set of path segments that are consistent with the sampled state information. The set of paths segments can be counted to determine their relative execution frequencies.

摘要： In a shared navigable workspace that is presented at more than one workstation, a region is made private in response to a user request. The user can also indicate the region's level of privacy by indicating levels of access of different users. The private region's contents are displayed only to users that have visual access; a non-informative pattern covers the region's area on the displays of other users. The private region and its contents can be modified only by a user with access to modify. When a user requests movement of a pointer into the private region, the pointer can be presented in the private region if the user has sufficient access; otherwise, the pointer would be kept outside the private region's boundary. If a user requests a transition into the private region by selecting a selectable transition unit, called a teleporter, the request would be denied unless the user has sufficient access. The pointer can operate according to a physical metaphor in which it picks up, holds, and puts down other objects, and the user can be permitted to move an object into the private region or to pick up an object within the private region only if the user has sufficient access. Within such a metaphor, a key display object held by a user's pointer can indicate that the user has sufficient access to move the pointer into a corresponding private region; if the user's pointer is not holding the key, it cannot move into the private region.

摘要： Security of information—both code and data—stored in a computer's system memory is provided by an agent loaded into and at run time resident in a CPU cache. Memory writes from the CPU are encrypted by the agent before writing and reads into the CPU are decrypted by the agent before they reach the CPU. The cache-resident agent also optionally validates the encrypted information stored in the system memory. Support for I/O devices and cache protection from unsafe DMA of the cache by devices is also provided.

摘要： Read requests to a commonly accessed storage volume are conditionally issued, depending on whether or not a requested data block is already stored in memory from a prior access or to be stored in memory upon completion of a pending request. A data structure is maintained in memory to track physical memory pages and to indicate for each physical memory page the corresponding location in the storage volume from which the contents of the physical memory were read and the number of virtual memory pages that are mapped thereto.

摘要： A method and tangible medium embodying code for allocating resource units of an allocatable resource among a plurality of clients in a computer is described. In the method, resource units are initially distributed among the clients by assigning to each of the clients a nominal share of the allocatable resource. For each client, a current allocation of resource units is determined. A metric is evaluated for each client, the metric being a function both of the nominal share and a usage-based factor, the usage-based factor being a function of a measure of resource units that the client is actively using and a measure of resource units that the client is not actively using. A resource unit can be reclaimed from a client when the metric for that client meets a predetermined criterion.

摘要： Methods and systems for managing distribution of host physical memory (HPM) among virtual machines (VMs) executing on a host via a hypervisor are presented, where each VM has guest system software including an operating system. A method includes an operation for reserving, by a balloon application executing in a first VM, a guest virtual memory (GVM) location in the first VM. The GVM location is mapped to a guest physical memory (GPM) location, which is mapped to a host physical memory (HPM) location. The balloon application is responsive to the hypervisor for reserving memory. Further, the method includes operations for writing a value to the reserved GVM location and for remapping a plurality of GPM locations containing the value to a single HPM location. The remapping is performed by a content-based page sharing component of the hypervisor. Additionally, the method reclaims the HPM location when the HPM location is freed due to the remapping, and assigns the reclaimed HPM location to a different VM or to a pool of available HPM locations.
