Me still waitin'. Maybe still flying over the ocean.
What partner card? Asus/EVGA/Gainward/Zotac?

flashjh 2013-02-27 07:21

EVGA - I had a pre-order in for Asus, but I checked at Newegg earlier today and they had the EVGAs in stock, so I ordered that one and cancelled the other order. It's supposed to be here on Friday.

CUDA 5.0 compile
 
I've reset up my build environment for CUDA 5.0 on Win64.
Here's a [URL="https://dl.dropbox.com/u/72392549/CUDALucas-2.04%20Beta-5.0-x64.exe.zip"]ZIP[/URL] with CUDALucas@latest SVN and @SM={2.0,3.5} and the necessary dlls (8.5 MB).
I've tested 2.0 with 216091: OK
I've tested 3.5 with 216091: CUFFTERR (Titan version but I don't have mine yet).
I only did these 2 tests as it's late.

Maybe this is useful for somebody. I'd love to hear from successful Titan runs. ;-)
Greetings, Sebastian

The latest stuff on SF has some serious problems with the fft changing code. That has hopefully been fixed, but I don't see the new code with the fix anywhere up there. If it has the x_packed variable in it, its ok.

I'll update your changes in a few hours. (Did you get my email about getting committ access?)

owftheevil 2013-02-28 23:23

Yes, got the email, but have been too busy to do anything about it yet. Sounds like a good idea.

Have you started the update? I can take the changes and test and upload... I have some time tonight.

The most recent CUDALucas.cu file is giving me a problem compiling:

[CODE]Line 703: struct stat FileAttrib;
Line 717: if(stat(chkpnt_cfn, &FileAttrib) == 0) fprintf (stderr, "\nUnable to open the checkpoint file. Trying the backup file.\n");
Line 737: if(stat(chkpnt_cfn, &FileAttrib) == 0) fprintf (stderr, "\nUnable to open the backup file. Restarting test.\n");
[/CODE]

Compiler output:
[CODE]C:\CUDA\src>make -f makefile.win
makefile.win:12: Extraneous text after `else' directive
"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v5.0/bin/nvcc" -c CUDALucas.

CUDALucas.cu(703): error: incomplete type is not allowed

CUDALucas.cu(717): error: incomplete type is not allowed

CUDALucas.cu(737): error: incomplete type is not allowed[/CODE]

If you let me know what you're trying to do with the struct maybe I can figure out how to make MSVS happy.

ZIP removed due to code problems mentioned above.

I'm using a .cu file that was emailed to me. I haven't uploaded to svn yet because I want to get it to compile first. If you want to take a look at it, PM me your email address.

owftheevil 2013-03-01 12:31

Flash, you can take those lines out if you want. They are just checking if the file exists before printing the message that they can't be opened.
