Re: random access memory cycle runs ten times faster on win32 platform than on linux - strange

[Joern Rennecke]

Quoting Béla MIHALIK <bela.miha...@gmail.com>:

If I compile it with mingw32 compiler, or VisualC++ then it gives good result.

Here are my results for memory bandwith test:

Linux: 373.574249 MB/s
Win32: 4468.297363 MB/s

I don't think that has anything to do with the code generated by the compiler;
rather, I think the random function you use on Windows is broken.
The bandwidth is way too high for pages misses in most loop iterations.
