Hello, SETTING: - There is an application, written using Boost Template library, meant for QUICK processing of bulk text files (cca 50-100Gb each). - There is a huge, quick and expensive piece of hardware with HUGE amount of RAM and multiple CPU. - There is [theoretically] any possible UNIX-like OS, even Microsoft Windows (R) is considered. - Boost Thread Pool extension is used; previously memory mapped files through memory_segment have been used, now got rid of the entire Boost::interprocess. - There are NO explicit data items in the application's algorithm to be shared by threads, each has its own piece of input file, thus - there is NO explicit concurrency. PROBLEM: - Ensure fast processing without locks and threads sleeping. Currently the threads sleep on some internal mutex. We thought it's been boost::interprocess (specifically - mmap, wrapped by a mutex), but it apparently isn't so. SPECIFIC QUESTION: - How could we get rid of Boost locks? Mike
