triqs::stat::accumulator::log_bin_errors_all_reduce

#include <triqs/stat/accumulator.hpp>

Synopsis

auto log_bin_errors_all_reduce (communicator c) const

Returns the standard errors for data with different power-of-two capacity, reduced from data over all MPI threads. The final answer is reduced only to the zero MPI thread (not all reduce).

Parameters

• c TRIQS MPI communicator

Returns

std::vector, where element v[n] contains the standard error of data binned with a bin capacity of $$2^n$$. The return type is deduced from nda::real(T), where T is the type defining the accumulator. Reduced only to zero MPI thread.
