GpuGrid acemdlong 6.16 (cuda42) i686/win 1WU

[Christopher Herr]

Hi everyone,

since there seems to be a 'desire'/need for a working GpuGrid app_info with CUDA 4.2 support I will give one here:

Download http://www.gpugrid.net/download/acemd.2562.cuda42
and http://www.gpugrid.net/download/cudart32_42_9.dll
and http://www.gpugrid.net/download/cufft32_42_9.dll
and http://www.gpugrid.net/download/tcl85.dll

and put all those files into the GpuGrid project folder.

For Windows 7 open System settings, Advanced system settings, Environment variables and enter 'SWAN_SYNC' as new variable for the system with value '0' (exactly written that way without the quotation marks, of course).
Rumor had it, this was no longer necessary or of any use, but I respectfully disagree, it will shave off a couple/dozens of minutes of the runtimes in average, though it makes my systems at least a little unresponsive at times! Well, it is "good" ole CUDA...

Another good idea is to reserve the thread/core via ProLasso ( http://bitsum.com/prolasso.php ), say thread/core 0 to 'acemd*' and give this wildcard string also high CPU priority and restrict the other say CPU applications run by BOINC to the remaining threads/cores.

Content of the app_info, running one at a time with one CPU thread/core support, to be saved into a text file named 'app_info.xml' (again without quotation marks) in the GpuGrid project folder:

Hope this works out for you!

Note that older cards (with Compute Capability beneath 2.0) can not run the CUDA 4.2 application!
--> For those I will post the CUDA 3.1 application and app_info as well.
Note as well that Fermi generation cards will need 25 mV more voltage on the core with the same otherwise stable OC to run this CUDA 4.2 application reliably!
