MCE spawns a pool of workers and therefore does not fork a new process per each element of data. Instead, MCE follows a bank queuing model. Imagine the line being the data and bank-tellers the parallel workers. MCE enhances that model by adding the ability to chunk the next n elements from the input stream to the next available worker. %package tools Summary: Many-core Engine command line tools Requires: %{name} = %{?epoch:%{epoch}:}%{version}-%{release} Requires: grep, gzip %description tools This package delivers command line tools like mce_grep(1) that utilize the Many-core Engine (MCE) Perl library. %prep %setup -q -n MCE-%{version} # Fix sharp-bang line %patch -P 0 %build MCE_INSTALL_TOOLS=1 perl Makefile.PL INSTALLDIRS=vendor make %{?_smp_mflags} %install make pure_install DESTDIR=%{buildroot} find %{buildroot} -type f -name .packlist -delete %{_fixperms} -c %{buildroot} # Add symlinks for grep variants ln -s mce_grep %{buildroot}%{_bindir}/mce_egrep ln -s mce_grep %{buildroot}%{_bindir}/mce_fgrep ln -s mce_grep %{buildroot}%{_bindir}/mce_zgrep ln -s mce_grep %{buildroot}%{_bindir}/mce_zegrep ln -s mce_grep %{buildroot}%{_bindir}/mce_zfgrep %check make test %files %license LICENSE Copying %doc Changes Credits README.md %doc %{perl_vendorlib}/MCE.pod %doc %{perl_vendorlib}/MCE/Core.pod %doc %{perl_vendorlib}/MCE/Examples.pod %dir %{perl_vendorlib}/MCE/ %dir %{perl_vendorlib}/MCE/Core/ %{perl_vendorlib}/MCE.pm %{perl_vendorlib}/MCE/Candy.pm %{perl_vendorlib}/MCE/Channel/ %{perl_vendorlib}/MCE/Channel.pm %{perl_vendorlib}/MCE/Child.pm %{perl_vendorlib}/MCE/Core.pm %{perl_vendorlib}/MCE/Core/Input/ %{perl_vendorlib}/MCE/Core/Manager.pm %{perl_vendorlib}/MCE/Core/Validation.pm %{perl_vendorlib}/MCE/Core/Worker.pm %{perl_vendorlib}/MCE/Flow.pm %{perl_vendorlib}/MCE/Grep.pm %{perl_vendorlib}/MCE/Loop.pm %{perl_vendorlib}/MCE/Map.pm %{perl_vendorlib}/MCE/Mutex.pm %{perl_vendorlib}/MCE/Mutex/ %{perl_vendorlib}/MCE/Queue.pm %{perl_vendorlib}/MCE/Relay.pm %{perl_vendorlib}/MCE/Signal.pm %{perl_vendorlib}/MCE/Step.pm %{perl_vendorlib}/MCE/Stream.pm %{perl_vendorlib}/MCE/Subs.pm %{perl_vendorlib}/MCE/Util.pm %{_mandir}/man3/MCE.3* %{_mandir}/man3/MCE::Candy.3* %{_mandir}/man3/MCE::Channel.3* %{_mandir}/man3/MCE::Channel::Mutex.3* %{_mandir}/man3/MCE::Channel::MutexFast.3* %{_mandir}/man3/MCE::Channel::Simple.3* %{_mandir}/man3/MCE::Channel::SimpleFast.3* %{_mandir}/man3/MCE::Channel::Threads.3* %{_mandir}/man3/MCE::Channel::ThreadsFast.3* %{_mandir}/man3/MCE::Child.3* %{_mandir}/man3/MCE::Core.3* %{_mandir}/man3/MCE::Core::Input::Generator.3* %{_mandir}/man3/MCE::Core::Input::Handle.3* %{_mandir}/man3/MCE::Core::Input::Iterator.3* %{_mandir}/man3/MCE::Core::Input::Request.3* %{_mandir}/man3/MCE::Core::Input::Sequence.3* %{_mandir}/man3/MCE::Core::Manager.3* %{_mandir}/man3/MCE::Core::Validation.3* %{_mandir}/man3/MCE::Core::Worker.3* %{_mandir}/man3/MCE::Examples.3* %{_mandir}/man3/MCE::Flow.3* %{_mandir}/man3/MCE::Grep.3* %{_mandir}/man3/MCE::Loop.3* %{_mandir}/man3/MCE::Map.3* %{_mandir}/man3/MCE::Mutex.3* %{_mandir}/man3/MCE::Mutex::Channel.3* %{_mandir}/man3/MCE::Mutex::Channel2.3* %{_mandir}/man3/MCE::Mutex::Flock.3* %{_mandir}/man3/MCE::Queue.3* %{_mandir}/man3/MCE::Relay.3* %{_mandir}/man3/MCE::Signal.3* %{_mandir}/man3/MCE::Step.3* %{_mandir}/man3/MCE::Stream.3* %{_mandir}/man3/MCE::Subs.3* %{_mandir}/man3/MCE::Util.3* %files tools %{_bindir}/mce_grep %{_bindir}/mce_egrep %{_bindir}/mce_fgrep %{_bindir}/mce_zgrep %{_bindir}/mce_zegrep %{_bindir}/mce_zfgrep %changelog * Mon Jan 20 2025 Paul Howarth - 1.901-2 - Rebuilt for https://fedoraproject.org/wiki/Fedora_42_Mass_Rebuild * Fri Jan 3 2025 Paul Howarth - 1.901-1 - Update to 1.901 (rhbz#2335354) - Add MCE::Core package for future development * Tue Sep 10 2024 Paul Howarth - 1.900-1 - Update to 1.900 (rhbz#2310966) - Improve MCE::Child exiting when signaled * Fri Sep 6 2024 Paul Howarth - 1.899-1 - Update to 1.899 - Fix for MCE::Child and MCE::Channel signal anomaly (GH#24) * Thu Aug 22 2024 Paul Howarth - 1.898-1 - Update to 1.898 - Fix for MCE::Child, Can't call method "len" on an undefined value during global destruction (GH#22) * Sun Jul 21 2024 Paul Howarth - 1.897-2 - Rebuilt for https://fedoraproject.org/wiki/Fedora_41_Mass_Rebuild * Thu Jun 20 2024 Paul Howarth - 1.897-1 - Update to 1.897 - In scalar context, the init function in MCE Child and models Flow, Grep, Loop, Map, Step, and Stream returns a guard to call finish automatically upon leaving the { scope } (i.e. omitting finish) - Add out_iter_callback to MCE::Candy * Wed Jun 12 2024 Paul Howarth - 1.896-1 - Update to 1.896 (rhbz#2291411) - Weaken internal core MCE reference to reap workers automatically upon leaving the scope i.e. omitting shutdown - Note: No change to MCE models Flow, Grep, Loop, Map, Step, and Stream - Call finish explicitly to reap workers - This resolves the case when omitting calling $mce->run(), $mce->run(1) or $mce->shutdown() inside a scope, causing workers to linger around until completion of the script * Tue Jun 11 2024 Paul Howarth - 1.895-1 - Update to 1.895 (rhbz#2291112) - Revert back to calling CORE::rand() to set the internal seed;

this addresses CPAN RT#105557 and CPAN RT#105559 - Added new MCE option loop_timeout to prevent the MCE Manager process from hanging perpetually; the manager process wrongly assumes a worker is still running when the worker died in an uncontrollable manner (CPAN RT#111780) ENHANCEMENTS - Perl 5.10.1 or later is required to run MCE 1.7; Perl < 5.10.1 lacks 'overloading.pm' - Added code in MCE::Grep's documentation for parsing huge files - Added support for running MCE with Perl under MobaXterm on Windows - MCE/examples and MCE/images are no longer included with the distribution: these are maintained separately at https://github.com/marioroy/mce-examples and https://github.com/marioroy/mce-assets respectively - MCE performs channel locking via a pipe or socket depending on platform; previously, locking was through file locking using flock - this resolves the slow locking performance on Cygwin - Optimized signal handling including improved support on Windows - Reduced overhead during spawning and job submissions on Windows and Cygwin; this enables IPC to complete up to 20x faster, thus benefiting Monte-Carlo simulations; e.g. calling ->run(0) or ->process(...) repeatedly - The MCE::Flow and MCE::Step Models can take an anonymous array for specifying use_threads uniquely for sub-tasks NEW FEATURES - Added MCE::Hobo for running code asynchronously, which provides async/join functionality for processes similarly to async/join in threads;

this is necessary for running with Tk and child processes or with use_threads => 0 - Seeds the Math::Random generator automatically when present for non-threads to avoid child processes sharing the same seed value as the parent and each other; the new seed is computed using the current seed, thus it's okay to set the seed at the application level for predictable results - Simplify find command using -delete - Reduce scope of requires filter, drop redundant provides filter * Mon Jun 15 2015 Paul Howarth - 1.608-2 - Perl 5.22 rebuild * Fri Apr 10 2015 Paul Howarth - 1.608-1 - Update to 1.608 BUG FIXES - Updated t/01_load_signal_arg.t to address false-positive from bug fix in 1.606 ENHANCEMENTS - Replaced (-e) with (perl) for the $prog_name value in MCE::Signal;

these preserve output order and cover the two general use cases * Wed Mar 18 2015 Paul Howarth - 1.603-1 - Update to 1.603 ENHANCEMENTS - A safer solution for the die handler in MCE::Signal and MCE::Core::Worker - Moved ->forchunk, ->foreach, and ->forseq sugar methods to MCE::Candy; stubs exist in MCE so there's no breakage to existing apps - Removed the link to MCE::Shared on the main page * Tue Mar 17 2015 Paul Howarth - 1.602-1 - Update to 1.602 BUG FIXES - Updated die handler inside MCE::Core::Worker and MCE::Signal (CPAN RT#102802) ENHANCEMENTS - MCE child processes call CORE::exit during exiting; previously CORE::kill - Improved IPC stability on Windows and Cygwin - Multiple calls to mutex->lock by the same process or thread is now safe; the mutex will remain locked until mutex->unlock is called * Mon Mar 16 2015 Paul Howarth - 1.601-1 - Update to 1.601 BUG FIXES - Updated Makefile.PL allowing installation of bin/mce_grep (CPAN RT#102040);
