I'm testing the Release 4.0 (5th Oct, 2017) binaries for macOS
(macOS.zip) on a Mac High Sierra (10.13) virtual machine from
TechsViewer
(https://techsviewer.com/install-macos-high-sierra-virtualbox-windows/).
I'm using the homebrew version of GNU sort/split utilities. The host
machine is an 8 virtual core i7 4 Ghz with 32GB RAM and 500GB SSD. The
virtual guest is configured with 24 GB RAM and six cores.
I've found two problems and I hope someone can help.
1. train-model.perl works all of the way through. The sort/split
utilities work fine. The problem is mgiza in step 2 took almost 3
hours to complete with a small 15,000 segment parallel corpus. Step
2 using the same corpus on the native Windows host takes less than
10 minutes. That step with the Ubuntu 16.04 binaries running on
Windows Subsystem for Linux (WSL) takes 9 1/2 minutes.
Observing the Mac's Activity Monitor during step 2 shows that mgiza
was running 6 threads, but the total CPU load was only 115%. All the
other macOS binaries ran at a comparable speed to the other
platforms' binaries. for example, when the moses binary runs with 6
threads, the monitor shows it's consuming nearly 550%.
Last year, we cross-compiled our own macOS binaries on Linux host
using circa Moses 3 source. We experienced the same slow performance
with mgiza binary on an old Mac notebook hardware. At the time, we
wrote delayed work because we thought slow performance was due to
the cross-compile settings and/or the slow hardware. After slow
results with the Moses4 mgiza binary, I re-cross-compiled the mgiza
binary on our system and it was also dead slow on the 10.13 guest
taking almost 3 hours.
These tests were run on a very fast host machine with a virtual
guest. Using Hieu's binaries or mine seems to run against those
assumptions that hardware/cross-compiler are totally at fault. Has
anyone else experienced this kind of slow performance?
2. The lmplz binary fails on this host with this message. Was this not
compiled with static links for a reason? Where can I find the
necessary libraries?
$ ./lmplz
