tachyon example

[rheiland]

When I run the tachyon example (tbb21_20080605/examples/parallel_for/tachyon on OSX 10.4), it seems to run fine on my 2-core machine, showing the expected speedup, but I'm curious about the visual output. The first rendering has a narrow sliver (single row of pixels?) of color at the very bottom, otherwise black; the next rendering has a narrow sliver in the middle row; the third has a "fat L" shaped block in the left-center.

Anyone have similar experience? Is this expected?

thanks, Randy

I don't know how it is possible on Mac. We've seen something similar with old versions of TBB on Linux.
Please, give more information about your system, run:
sw_vers; system_profiler SPApplicationsDataType | grep Xcode

P.S. I'll be out for a couple of weeks.

The same happens on my system.

Output from sw_vers; system_profiler SPApplicationsDataType | grep Xcode:

ProductName: Mac OS X
ProductVersion: 10.5.6
BuildVersion: 9G55
Xcode:
Get Info String: Xcode version 3.1.2
Location: /Developer/Applications/Xcode.app

Any ideas why this is happening?
