Member Function Documentation

void graphchi::stripedio::allow_preloading ( std::string  filename )

inline

Call to allow files to be preloaded. Note: using this requires that all files are accessed with same path. This is true if standard chifilenames.hpp -given filenames are used.

template<typename T >

void graphchi::stripedio::managed_pwritea_async ( int  session, T **  tbuf, size_t  nbytes, size_t  off, bool  free_after  )

inline

Memory managed versino of the I/O functions.

bool graphchi::stripedio::pinned_session ( int  session )

inline

Pinned sessions process files that are permanently pinned to memory.
