AllegroGraph 64-bit RDFStore
Efficiently Processing Billions of RDF Triples

AllegroGraph efficiently performs the three most important tasks for a
triple store: to load, store, and query data.

- Loading of triples, through its highly optimized RDF/XML and N-
Triples parsers, is best-of-breed, particularly on large files. With
just standard x86 64-bit hardware, it can load gigabytes of RDF data
in minutes.

- Storage is persistent, including between application launches in
on-disk binary trees. There is no additional serialization or
deserialization overhead.

- Querying is both flexible and performant. Multiple indices support
fast access through a simple triple-level API, Allegro Prolog, or
SPARQL (the emerging W3C standard RDF query language). When querying
for a particular subject with ten triples, AllegroGraph can retrieve
about 40,000 triples per second, from disk.

2. Fair multiprocessing example

If you run multiple processes in a Lisp application, this example
illustrates how to efficiently allocate processor time between the
processes and how often to switch between processes. In this article,
we discuss the allocation issue and demonstrate a couple of ways to
control the frequency of process switching.
