// typedef single TFloatingPointPrecision;
typedef double TFloatingPointPrecision;
TFloatingPointPrecision mStopX; TFloatingPointPrecision mStopY; TFloatingPointPrecision mDirectionX; TFloatingPointPrecision mDirectionY; TFloatingPointPrecision mSpeed; TFloatingPointPrecision mCurrentX; TFloatingPointPrecision mCurrentY; int mColor;
if I switch this kernel from single to double precision the kernel fails ?
Any idea what could be wrong ?
All code is basically very simple.
Only thing I can think of is that the kernel is somehow running out of memory.
But with 1 GB of RAM that shouldn’t be happening…
Compiles tried with textpad and parameters:
cuda toolkit 5.5:
$File --ptx --device-debug --machine 32 -arch sm_20
cuda toolkit 4.2:
$File --ptx -G0 --machine 32 -arch sm_20 -Xptxas -v
Now luck with double precision.
Graphics Card is GT 520 with compute 2.1 support ?!?
(I can’t debug it at the moment… since vs2010 and cuda toolkit 5.5 is giving me the craps.)
