Thank you, liz and woolfy for keeping Perl alive. I do not know why but persisted until reaching completion with the MCE and MCE::Shared modules. I know that Perl is used a lot in science. Recently, received a nice email message.
MCE is a major feature of the HPC::Runner::Command libraries, which are is currently a production software that runs all of our projects across the HPC. It is used daily, more than daily if you count actual compute hours instead of just projects. It definitely would not have come as far without your awesome help when it was first starting and you wrote out the thread management.
