-----Original Message----- On Behalf Of Roman Dementiev Subject: [boost] A library: out-of-core containers and algorithms
Hello,
I am developing a library called Stxxl. It is an implementation of 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.
Currently I have implemented vector, stack, and priority_queue. External memory map, list, and queue are coming soon. The containers take only specified (given) fixed amount of main memory, but can contain more elements than can fit into the main memory. The containers are compatible with STL algorithms, an example:
#include <stxxl>
// ten billion doubles stxxl::vector<double> HugeVector(10ULL * 1000000000ULL); std::fill(HugeVector.begin(), HugeVector.end(), 0.0);
[Brian Braatz] Roman- Thank you for submitting this. I am interested in this library and encourage you onward in bringing this to boost. Question: In a nutshell, if you could please describe * How it works * what the implications\dark corners are Are you using memory map files? What other libraries or os specific functions does your library need. Thank You Brian Braatz
