| Version: 1.889.0 | Vendor: openSUSE |
| Release: bp156.1.2 | Build date: Tue May 21 03:26:04 2024 |

| Summary: Many-Core Engine for Perl providing parallel processing capabilities | |
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.

processing small input sizes.

The main difference is that these lack freeze-thaw serialization.
MCE::Channel::MutexFast, MCE::Channel::SimpleFast, and
MCE::Channel::ThreadsFast.

This update required undoing optimizations specific to scalar args.
Essentially, IPC involves serialization for everything going forward.
Install Sereal::Encoder and Sereal::Decoder for better performance
in Perl 5.8.8+.
* MCE options flush_stdout, flush_stderr, and flush_file now default to
enabled for the MCE->print, MCE->printf, and MCE->say output routines.
* Improved MCE::Child with threads-like detach capability. See POD.
* Improved IPC in MCE::Queue with permanent fast-like dequeue including
dequeue_nb. Going forward, the fast and barrier options are silently
ignored if specified (i.e. no-op).

See POD section labled "DEFER SIGNAL" in MCE::Signal.
* Reverted $child->exit back to sending the SIGQUIT signal in MCE::Child
now that MCE::Shared::Server 1.863 defers signal during IPC.
* Improved reliability for spawning MCE and MCE::Child inside threads
including nested parallelization, made possible using a global lock
$MCE::_GMUTEX.
* Updated signal handling in mce-examples/framebuffer on GitHub.

- updated to 1.844
see /usr/share/doc/packages/perl-MCE/Changes
1.844 Wed Aug 14 21:30:00 EST 2019
* Resolved MCE stalling when specifying max_retries with init_relay.
Ditto for loop_timeout with init_relay on UNIX platforms.
Thank you, Chris Denley.
* Enhanced loop_timeout to handle workers dieing uncontrollably from
any user_tasks (i.e. task_id >= 0). Previously, only task_id == 0.
* Improved IPC on the Windows platform for edge case when a worker is
awaiting input while the manager process is restarting a worker.
* MCE, MCE::Child workers exit immediately upon receiving a SIGSEGV signal.
This safeguards IPC from stalling inside the manager process.
* Enhanced the _wait_one private function in MCE::Child.
* Removed Prima from the list for auto-enabling the posix_exit option.
Prima (since 1.52) is parallel safe during global cleanup.
* Reached 100% Pod coverage.
* Wed Jul 24 2019 Stephan Kulow <coolo@suse.com>
- updated to 1.843

1.841 Sun Jul 07 23:30:00 EST 2019
* Disabled t/04_channel_threads testing on Unix platforms for Perl less than
5.10.1. Basically, the MCE::Channel::Threads implementation is not supported
on older Perls unless the OS vendor applied upstream patches (i.e. works on
RedHat/CentOS 5.x running Perl 5.8.x).
* Added LIMITATIONS section to MCE::Channel::Threads.
1.840 Sun Jul 07 05:00:00 EST 2019
* Update MCE::Channel POD documentation.
1.839 Sun Jul 07 04:30:00 EST 2019
[NEW FEATURES]
* Added MCE::Mutex::Channel2 providing two locks using a single channel.
The secondary lock is accessible by calling methods with the '2' suffix.
E.g. primary mutex ->lock, ->unlock; secondary mutex ->lock2, ->unlock2
* Added MCE::Channel providing queue-like and two-way communication
supporting threads and processes.
* Added MCE::Child and compatibility with Perl 5.8. MCE::Child is based on
MCE::Hobo, but using MCE::Channel for data retrieval without involving
a shared-manager process.
* Added MCE::Channel examples { channel1.pl and channel2.pl } using
threads and MCE::Child respectively.
https://github.com/marioroy/mce-examples/tree/master/chameneos
[ENHANCEMENTS]
* IPC update; removed unnecessary overhead including private methods
_sysseek and _syswrite from MCE::Util (no longer needed).

* Updated MCE::{ Flow, Grep, Loop, Map, Step, and Stream } documentation
on passing an array reference versus a list for deeply input data.
* Updated and re-organized the top-level MCE documentation, particularly
improved clarity for the 'MCE Models' section.

* Results were captured on a fast 8 core system running CentOS Linux 7.
The thing to take from this is that running many workers "no longer"
results in up to 5.6x penalty regarding IPC.
1.824 Sat Apr 01 01:00:00 EST 2017
* Completed validation for running MCE on a box having 100+ cores.
* Tuned the number of data-channels for IPC. Set upper limit in
MCE::Core::Input::{ Handle and Sequence } to not impact the
OS kernel. The result is better performance, yet graceful.
