C++ STL drop-in replacement for extremely large datasets

STXXL provides an STL replacement using an abstraction layer to storage devices to allow for the optimal layout of data structures. This allows for multi-terabyte datasets to be held and manipulated in standard C++ data structures, whilst abstracting the complexity of managing this behaviour efficiently. STXXL utilises multi-disk I/O to speed up I/O bound calculations. STXXL has been developed at the University of Karlsruhe.
Package version:1.3.1-4



STXXL is an implementation of the C++ standard template library STL for
external memory (out-of-core) computations, i. e. STXXL implements containers
and algorithms that can process huge volumes of data that only fit on disks.
While the closeness to the STL supports ease of use and compatibility with
existing applications, another design priority is high performance.

libstxxl (1.3.1-3) unstable; urgency=low

  * Team upload.
  * Fix build failure with GCC 4.7, thanks to Matthias Klose (Closes: #672055)
  * Bump standards version to 3.9.3
  * Remove useless quilt references in debian/control & debian/rules.


Version 1.3.1 (10 March 2011)

* Possibly breaking changes
  - No longer open syscall files with O_SYNC|O_DSYNC|O_RSYNC by default when
    doing direct I/O, to avoid a write performance decrease starting with Linux
    kernel version 2.6.32.
    A stxxl::file::SYNC flag has been added to allow forcing the O_*SYNC flags
    when opening files.
  - Lock files by default (if implemented for this fil


* asynchronous pipelining 
  (currently being developed in branch parallel_pipelining_integration)
