This contrasts with the traditional approach of combining manual processes, desktop project tools, and PPM applications for each project portfolio environment.
It is being widely used to collect low level performance metrics (e.g. instruction counts, clock cycles, cache misses) of computer systems running UNIX/Linux operating systems. PAPI provides predefined high level hardware events summarized from popular processors and direct access to low level native events of one particular processor.
Pages in the page cache modified after being brought in are called dirty pages. [5] Since non-dirty pages in the page cache have identical copies in secondary storage (e.g. hard disk drive or solid-state drive), discarding and reusing their space is much quicker than paging out application memory, and is often preferred over flushing the dirty pages into secondary storage and reusing their space.

Project production management (PPM) [1] [2] is the application of operations management [2] [3] to the delivery of capital projects. The PPM framework is based on a project as a production system view, [ 1 ] [ 2 ] [ 3 ] in which a project transforms inputs (raw materials, information, labor, plant & machinery) into outputs (goods and services).
A distinguishing feature of ClearCase is the MultiVersion File System (MVFS), a proprietary networked filesystem which can mount VOBs as a virtual file system through a dynamic view, selecting a consistent set of versions and enabling the production of derived objects. This was a departure from the repository-and-sandbox model because it ...
