A networked computer system has a plurality of servers and a plurality of distributed clients, which may be devices or computers. Each client has a boot operating system (OS). Upon startup, the boot OS in each client automatically initiates a connection to one of the servers via the Internet. The boot OS can detect the type of medium (e.g., cable modem, DSL) to which the client is connected. The server automatically downloads a base OS and dynamically configures a suite of applications on the client without running the standard installation programs. One included application is an Internet telephony application, allowing a user to plug a standard telephone into the client appliance or computer, pick up the telephone, and automatically dial out using long distance Internet telephony. Optionally, the server may download a plurality of operating systems that are automatically initiated to run concurrently on the client. The clients use a random access memory (RAM) caching technique. A first portion of each OS or application is downloaded at startup and maintained in the client RAM, containing the files needed to launch the OS or application. If the client processes a request for an OS or application program file not in the client's RAM, the requested file is automatically downloaded from the server.

Described herein is an operator-based approach to representing dataflows. A dataflow is a set of one or more operations and one or more flows of data that are processed successively by the set of operations. A dataflow is described by a generic description in which operations in a dataflow are represented by operators. An operator defines a primitive operation (e.g. join, filter), specifying not only the type of operation, but the inputs and outputs, rules, and criteria that govern the operation. From the generic description, a code implementation is generated that may be completely executed on a source database system and target data warehouse, without need for an intermediate system to participate in the execution of the code implementation, such as a data movement engine.

A network caching system has a multi-protocol caching filer coupled to an origin server to provide storage virtualization of data served by the filer in response to data access requests issued by multi-protocol clients over a computer network. The multi-protocol caching filer includes a file system configured to manage a sparse volume that “virtualizes” a storage space of the data to thereby provide a cache function that enables access to data by the multi-protocol clients. To that end, the caching filer further includes a multi-protocol engine configured to translate the multi-protocol client data access requests into generic file system primitive operations executable by both the caching filer and the origin server.

A graphics processor performs culling of invisible primitives in a vertex processing unit that includes a geometry shader or other processing engine that performs per-primitive operations. Primitives can be culled after clip space coordinates for the vertices have been computed and in some instances before at least one other vertex attribute has been computed. To the extent that this early culling reduces the number of vertices for which the full set of attributes is computed or reduces the number of primitives or vertices delivered to downstream units, throughput of the processor is increased.

A system for network accounting statistics collection including a statistics collector associated with each packet forwarding engine. Each statistics collector has one or more accounting elements, each of which includes some number of counters, such as packet and byte counters. Each statistics collector receives accounting instructions from the associated forwarding engine for packets processed by the forwarding engine, including packets that will be discarded without being forwarded. Each accounting instruction includes an identifier uniquely indicating one of the accounting elements, and information used to increment the counters within the accounting element. Upon receipt of an accounting instruction, the receiving statistics collector increments the counters in the accounting element. The accounting instruction is a relatively simple primitive operation in the disclosed system, enabling high-speed operation. Each statistics collector collects data over a fixed sampling interval that may range from a number of milliseconds to one or more minutes. Each sampling period begins with a reset of an accounting element store, and ends with at least one set of data being flushed to a management system for further processing and/or formatting.

An electronic mail (“e-mail”) system is described that provides a methodology that allows the system to determine when it is appropriate to relay e-mail messages, particularly from “roaming” users. In basic operation, the methodology of the present invention first checks whether the client has been authenticated. If not, the decision of whether relaying is allowed may be subject to other rules in the system, such as whether the user currently resides behind the company's firewall. Of interest herein is a case where the client has been authenticated. In that case, the system can allow relaying for everyone who has a certificate (“cert”) signed by certain certificate authorities (“CAs”). Additionally, the system can require specific cert subjects.

Differences between the migration operations are handled by variations in how the state of the data migration driver routine is initialized, including pointers to low-level routines. Furthermore, a table of actions can be used to direct the basic operation of object copying, external reference created, and object interning.

An application typically runs on top of an operating system. Some computing device have the ability to reboot and load a different operating system whenever an application or set of applications is run. If an old application requires an old operating system version, it is possible to load that OS instead. Every application can have its own version of the operating system. Only new applications or a small set of applications need to use the new OS—all the old applications may run their own older version of the OS. Patches or software updates can be applied only for particular applications. Other applications that need the same base OS but don't need the patch can skip using the patch. It is possible to determine what version the application is and selectively apply the patch based on the version of the application.

Systems, apparatus and methods for handling verification violations are disclosed. In one aspect, a method stores a list of fix information in addition to geometric shapes for each layer during verification, such as design rule checking For each primitive operation step performed during verification, two tasks are performed. First, if the primitive operation is a dimensional checking operation (i.e., width, spacing or enclosure), then for each violation, the first task creates fix information containing violation edge pairs and adds the created fix information to the fix information list on the output layer. Second, for all operations and after the output shapes on the output layer are generated, a second task passes the fix information on input layers which overlap any output shape of the output layer to the output layer's fix information list. Finally, fix guides for the final violation results are generated and drawn based on the final fix information list.

A multi-chip system and method are disclosed for incorporating a primitive assembler in each of one or more geometry chips and one or more rasterization chips. This system may allow per-primitive operations to be performed in the geometry chips, and also allow use of a vertex data interface for sending vertex data to the rasterization chips. The primitive assemblers in the geometry chips may assemble vertices into primitives for clipping tests. The geometry chips may also test an assembled primitive against the projected boundaries of a set of screen space regions, where each region is assigned to one of the rasterization chips. Those primitives residing in more than one region may be sub-divided into two or more new primitives so that each new primitive resides in only one screen space region. The geometry chip may then send the vertex data for each primitive to the corresponding rasterization chip.
