The object is obtained with the Unix::Processors::processors call. the operating system in a OS independent manner. .IP max_online 4 .IX Item "max_online" Return number of threading processors currently online. On hyperthreaded Linux systems, this indicates the maximum number of simultaneous threads that may execute; see max_physical for the real physical CPU count. .IP max_physical 4 .IX Item "max_physical" Return number of physical processor cores currently online. For example, a single chip quad-core processor returns four. .IP max_socket 4 .IX Item "max_socket" Returns the number of populated CPU sockets, if known, else the same number as max_physical. For example, a single chip quad-core processor returns one. .IP max_clock 4 .IX Item "max_clock" Return the maximum clock speed across all online processors. Not all OSes support this call. .IP processors 4 .IX Item "processors" Return an array of processor references. See the Unix::Processors::Info manual page. Not all OSes support this call. .SH DISTRIBUTION .IX Header "DISTRIBUTION" The latest version is available from CPAN and from . .PP Copyright 1999\-2017 by Wilson Snyder.
