6360282, Mar 19, 2002

Filed:

Mar 24, 1999

Appl. No.:

09/275203

Inventors:

Alan B. Langerman - Watertown MA
David A. Ford - Waban MA

Assignee:

Network Appliance, Inc. - Sunnyvale CA

International Classification:

G06F 1314

US Classification:

710 3, 710129

Abstract:

A user program directly accesses a storage device for I/O operations, bypassing the operating system. The user registers a virtual memory region and an âextentâ, or region, of the storage device with a host bus adapter. A virtual interface is created between the user and the storage device including a queue for transmitting commands from the user to the storage device. To perform I/O, the user creates a descriptor including command information identifying the type of I/O operation, a buffer handle identifying the registered virtual memory region, virtual memory address information identifying the locations of data buffers in the registered virtual memory region to be used for the I/O operation, an extent handle identifying the registered extent, and disk address information identifying an area within the registered extent to or from which data is to be written or read. The user posts this descriptor to the virtual interface by placed it on the associated queue. The adapter reads the descriptor and verifies that the descriptor and the data buffers are located within the registered virtual memory region identified by the buffer handle.

International Classification:

G06F 946

US Classification:

395275

Abstract:

Disclosed is a multiprocessor computer system including a plurality of processor modules with each of the processor modules including at least one processor and a cache memory which is shared by all of the processors of each processor module. The processor modules are connected to a system bus which comprises independent data, address, vectored interrupt, and control buses. A system memory which is shared by all the processor modules is also connected to the buses, and the cache memories in each processor module store those memory locations in the main memory most frequently accessed by the processors in its module. A system control module controls the operation and interaction of all of the modules and contains the bus arbiters for the vector, data and address buses. The system control module also controls the retrying of requests which are not completed and should any requester fail to obtain access to a bus, the system control module also unjams this deadlock. Each of these multiprocessor computer systems can be connected to another multiprocessor computer system through an interface which includes a cache for housing frequently accessed locations of the other multiprocessor system.

Abstract:

The present disclosure relates to a computer-implemented method for analyzing a product stream of a chemical reaction. The method includes withdrawing a portion of the product stream of the chemical reaction from a reactor, the portion of the product stream having a volume of less than about 200 μL. The method further includes mixing the portion of the product stream with a diluent to produce a sample and then transferring the sample to a liquid chromatography device. A measured chemical profile is then developed, via the liquid chromatography device, which can be used for process monitoring or real time decision making. In some embodiments, the method can include adjusting a reaction condition in the reactor based on differences between the measured chemical profile and a desired chemical profile.
