Limit TileDB core use to a given number of coresSource:
By default, TileDB will use all available cores on a given machine. In multi-user or multi-process settings, one may want to reduce the number of core. This function will take a given number, or default to smaller of the ‘Ncpus’ options value or the ‘"OMP_THREAD_LIMIT"’ enviroment variable (or two as hard fallback).
Value of CPUs used, if missing the smaller of a fallback of two, the value of ‘Ncpus’ (if set) and the value of environment variable ‘"OMP_THREAD_LIMIT"’ is used.
Optional logical toggle; if set, a short message is displayed informing the user about the value set.
As this function returns a config object, its intended use is as argument to the context
ctx <- tiledb_ctx(limitTileDBCores()). To check that the values
are set (or at a later point, still set) the config object should be retrieved via the
corresponding method and this
cfg <- config(ctx).
