Revision history for MCE
1.403 Sun Feb 17 15:00:00 EST 2013
* Wrap sub PDL::CLONE_SKIP into a no warnings 'redefine' block
MCE now works with PDL::Parallel::threads without any warnings
* Added missing examples/matmult/matmult_pdl_n.pl to MANIFEST
* Refactored strassen examples, memory consumption reduced by > than 50%
* Added matmult_pdl_o.pl -- uses PDL::Parallel::threads to share matrices
* Added matmult_pdl_p.pl -- matrix b is read from shared memory, not mmap
* Added strassen_pdl_n.pl -- additional improvements to memory reduction
* Added strassen_pdl_h.pl -- shown running with 4 workers (half and half)
* Re-ran matrix multiplication examples and updated results in README file
* Added -no_setpgrp option to MCE::Signal.pm
Ctrl-C does not respond when running /usr/bin/time mce_script.pl
* Added undef $buffer in a couple of places within MCE.pm
* Added David Mertens and Adam Sjøgren to CREDITS
* The send method now checks if sending > total workers after spawning
not before
1.402 Thr Feb 14 07:30:00 EST 2013
* Updated matrix multiplication examples including README
* Added examples/matmult/matmult_pdl_n.pl
1.401 Tue Feb 12 19:00:00 EST 2013
* Added sub PDL::CLONE_SKIP { 1 } to MCE.pm. Running PDL + MCE threads no
longer crashes during exiting.
* Updated matrix multiplication examples. All examples now work under the
windows environment no matter if threading or forking. Unix is stable as
well if wanting to use PDL + MCE and use_threads => 1 or 0.
* Added benchmark results for 2048x2048, 4096x4096, and 8192x8192 to the
README file under examples/matmult/
* Updated documentation
1.400 Mon Feb 11 07:00:00 EST 2013
* Slight optimization in the _do_callback method
* Added 2 new options: user_args and RS (record separator)
* Added new send method for sending data to workers after spawning and
prior to running
* The sequence option can now take an ARRAY reference
* Updated documentation on new features
* Added matrix multiplication examples
1.306 Sat Jan 05 18:00:00 EST 2013
* Added if statement around setpgrp(0,0). That function is not supported
under Windows.
* Updated logic for removing any remaining MCE session directories inside
MCE::Signal.
1.305 Sat Jan 05 16:00:00 EST 2013
* Added check for $^S to the DIE handler inside the _worker_main method
* Added setpgrp(0,0) to MCE::Signal's BEGIN block
* MCE::Signal points to a _mce_sess_dir hash in the event of a signal,
will remove the sess_dir(s) as well. This is needed when tmp_dir is
specified during instantiation and pointing to another location than
MCE::Signal::tmp_dir.
1.304 Wed Jan 02 22:00:00 EST 2013
* Added Oliver Gorwits to CREDITS for identifying 2 issues

* Bump version -- MCE.pm VERSION now matches with META.yml

* Task ID is never undef, therefore removed check inside
restart_worker and worker_do methods

$display_die_with_localtime and $display_warn_with_localtime
