Issue when using GPU accelerators
Posted: Wed Sep 28, 2016 12:53 pm
Hello,
There seems to be something wrong outside my code as I edit the default C compiler flags(CFLAGS) to "-ta=tesla", and the feedback is accelerate the part of code as follow.
But when I run the command which is ./SaturneGUI, I get some errors about accelerators. Here is the errors:
Is there an option to choose the available accelerators?
Best Regards,
Jackie

Current region was compiled for:
NVIDIA Tesla GPU sm30 sm35
Available accelerators:
device[1]: Native X86 (CURRENT DEVICE)
The accelerator does not match the profile for which this program was compiledBest Regards,
