... Up: Science Data Pipelines . ... The Chandra Automatic Data Processing System (AP) requires quick access to previously generated data. ... This archive interface layer includes an archive request queue, a data archiving server (darch), and an archive ``cache''. ... In our implementation, the cache is actually a directory where the data files reside, as shown in Figure 1 . ... If the data products are not in the cache, then the pipeline retrieves the files from the archive database. ...

Customers are: o PSO For all supported instrument modes, create and certify master calibration data, for following customers: o external user community (through the Archive calSelector service) o PSO (on-line pipeline system), quality feedback o QC group (for IDP projects) Collect, analyze, and report instrument QC1 parameters. ...

... You are here: start €Ё difx €Ё difx_monitor . ... difx:difx_monitor . ... Clients . ... To allow multiple clients to simultaneously receive this monitoring data, a monitor_server can be run which receives a copy of ALL visibilities and allows multiple clients to connect. The clients request which of the visibilities they require and monitor_server only sends on the products required (so e.g. a client can be run over a moderately slow link if it only requires a handful of products). ...

... A UNIX system has a lot of daemons. a database is the name given to the combination of a program that can manipulate data, together with the data that it acts upon. a record is a set of data about a person or item. Name, telephone number and postcode is an example of such a set. a field is one part of that record; the postcode for example. a delimiter character separates each field from the field preceding it and the field that follows it. ...

As it was already mentioned, the idea behind File Juggler is rather simple: using CGI scripts as processing tools and WWW browser as user interface, display the structure and content of typical anonymous FTP server in a convenient, easily navigated form. ... My P5-133 spends about 0.025 ms on one file when doing linear search with simple criterion (690 ms for 27,000 files, search for substring among file names/descriptions with 70 hits). ... Let's now look whether we can handle 1,000,000 files. ...
