AFMC (Australasian Fluid Mechanics Conference) is held biannually in Australia, and the 22nd AFMC2020 was…
In a previous post we compared the run time performance for Caelus 4.10 on six of the supported operating systems (Windows 7 Pro, Windows 8.1, Ubuntu 12.04, Ubuntu 14.04, RedHat EL 6.x, RedHat EL 7.x). Thius article presents the Mac OSX 10.9.5 and 10.10.1 results for the motorbike tutorial.
To facilitate comparison each operating system was installed onto the same hardware. As it was not possible to install OSX on the hardware used for the earlier post the results for the other operating systems had to be repeated on the new hardware. The execution time was taken from the log file for each simulation and the results for each tutorial have been normalised to the RHEL6.5 result, thus the computer specifications are irrelevant for this exercise.
From the cases tested some statistics can be generated as shown in the table below:
|Windows 7 Pro||1.44|
|Red Hat EL 7||1.06|
|Mac OS X 10.9.5||1.31|
|Mac OS X 10.10.1||1.28|
It is clear from the table that the Windows operating systems are the slowest of all operating systems tested. All Linux flavoured operating systems showed similar speed. The Mac OS X operating systems were better than Windows but slower than Linux.
