Thanks for the update!

With the new package it runs "out of the box".

In my case S=0 less than 1% CPU

From Stock 3.11 to this one my times goes from 80min to 45min.

Big improvment!
Thanks again.

cudart64_40_17.dll is a CUDA 4.0 DLL. The build is for CUDA 4.2.

So.... updating the drivers to v4.2 build 9 (cuda64_42_9.dll) would have worked. On the other hand, this is pretty good news in that using CUDA 4.0 build 17 would also work but requires renaming the 4.2 DLLs so it thinks they are v4.2 DLLs -- which works with the app_info but not very well as a standard app. I guess I should have put the driver version in the readme (e.g. 301.42 or higher).

Yes, but if I understand things correct:
collatz_3.11_windows_x86_64__cuda42.exe calls for cudart64_40_17.dll
I´ll suspect this is "hardcoded" in the build.

If I open collatz_3.11_windows_x86_64__cuda42.exe in NOTEPAD and search for cudart64_4 i find cudart64_40_17.dll not cuda64_42_9.dll

This is On MS Vista64 and a NV 560Ti

I found this in my Eventlog:
- <Event xmlns="">
- <System>
<Provider Name="Application Error" />
<EventID Qualifiers="0">1000</EventID>
<TimeCreated SystemTime="2012-07-07T05:09:05.000Z" />
<Security />
- <EventData>


I Changed the Filename cudart64_42_9.dll to cudart64_40_17.dll
and uppdated the app_info.xml with the new filename.

It seems to work for me.
