Windows benhcmark differences between VS 2003 and VS 2005

Reported by: romw Owned by: romw
Priority: Blocker Milestone: 5.10
Component: Client - Daemon Version:
Keywords: Cc: davea

Description (last modified by Nicolas)

Default optimizations have changed between Visual Studio 2003 and Visual Studio 2005 which has lead to people reporting that their benchmark scores are worse then before.

Rebirther states: 

Benchmark results:
Number of CPUs: 2
829 floating point MIPS (Whetstone) per CPU (before 1400)
1119 integer MIPS (Dhrystone) per CPU (before 1200)

Looks like we'll need to play around with the optimization settings in 2005 a bit.

Anybody else want to report their scores?

(In [12465]) Rom 24 Apr 2007

  • fixes #122 - Windows benhcmark differences between VS 2003 and

VS 2005.

The default FP model has changed since 2003, so change how the

BOINC components are compiled so that they use /fp:fast instead of /fp:precise.

Take these with a grain of salt though... this computer has always benchmarked on the low side

MarekZ, Could you also post the 5.8.16 benchmark scores?

comment:9 Changed 17 years ago by marekz

The same box:
5.8.16 results:
Number of CPUs: 2
2015 floating point MIPS (Whetstone) per CPU
3687 integer MIPS (Dhrystone) per CPU <--- (looks quite strange, but I get it 4 times +/- 5 points)

Results for the 5.9.x are also medians calculated from four measurements (each after computer restart)

comment:10 Changed 17 years ago by marekz

I see, the variability of the Dhrystone score for the 5.9.5 is big enough:

I'm not sure why, but no other strong CPU-using programs running, no mouse or keyboard use, no strong network activity (like eMule etc.), no computer restarts this time. Really don't know what's happening here. :-)

Okay it appears the slower benchmark problem is now resolved.

At this point a 5-6% increase in benchmark scores it alright, it'll provide an incentive to upgrade to the latest release.

Now we'll just need to normalize the scores between Windows and Linux.

The first run was done with nothing extraneous running in the background and no activity on the computer. Skype and Firefox were shut down. Second run was done with normal programs running and typing in Open Office.

Compared to the the results for 5.9.5, they are consistent but still higher than 5.8.16.

As previously mentioned an increase of 5-6% in scores over VS 2003 is alright.

If anything it'll encourage people to upgrade.

What makes it so much better is we closed the FLOP scores to within 1% of the linux benchmark scores.

Note: See TracTickets for help on using tickets.
