OpenFOAM 성능비교 (윈도우 vs Linux vs Wine)

OpenFOAM Windows Timing Comparisons

Submitted by symscape on March 26, 2008 - 10:37.

Here are results of an execution time (as reported by OpenFOAM) comparison between OpenFOAM running on the same dual boot computer.
Computer specifications were:

• 2.6GHz Pentium 4 with Hyper Threading
• 32 bit
• 1GB RAM

The case was the icoDyMFoam (movingCone) OpenFOAM tutorial.

	Windows XP Pro SP2		Linux (Ubuntu 7.10)	Wine (v0.9.46)
	High Priority	Normal Priority
Time	65.708 s	68.942 s	50.8 s	67.3 s
% of Linux	129%	136%	100%	132%
Log File	windows-high	window-normal	linux	wine

Wine is a Windows emulator that runs under Linux.

 

Another Timing Comparison

Another timing comparison (suggested by Henry Weller) for a much larger 3D case using the same machine as previous.
The case was the Xoodles pitzDaily3D OpenFOAM tutorial, with the following modifications:

• on the internal cells and walls k was initialized to 2e-10 to avoid divide by zero
• limited to first 20 timesteps
• for Windows the file 0/b was renamed to 0/b_ to avoid conflict with the file 0/B (this is why the patch was updated)

	Windows XP Pro SP2	Linux (Ubuntu 7.10)	Wine (v0.9.46)
Time	739.906 s	524.84 s	702.27 s
% of Linux	141%	100%	134%
Log File	windows	linux	wine
