Function Documentation

◆ GetCurrentRSS()

size_t cbm::algo::GetCurrentRSS ( )

Get the current resident set size (pyhysical memory usage) of the process.

Returns: The current resident set size in bytes

Note: Returns zero if the value cannot be determined

Definition at line 15 of file System.cxx.

Referenced by cbm::algo::MemoryLogger::Log().

◆ GetGlobalSTLThreadPool()

task_thread_pool::task_thread_pool & cbm::algo::GetGlobalSTLThreadPool ( )

Get the global thread pool for parallel stl algorithms.

This function returns a reference to the global thread pool used by the parallel stl algorithms. At the beginning it's initialized with the number of available threads. Otherwise this function should only be used in conjunction with the parallel stl algorithms via poolstl.

Definition at line 8 of file Algorithm.cxx.

Referenced by main(), and Sort().

◆ GetPeakRSS()

size_t cbm::algo::GetPeakRSS ( )

Get the peak resident set size (pyhysical memory usage) of the process.

Returns: The peak resident set size in bytes

Note: Returns zero if the value cannot be determined

Definition at line 35 of file System.cxx.

Referenced by cbm::algo::MemoryLogger::Log().
