Hi,
I have this error by changing static value in the kernel by arg value :
Log = ptxas application ptx input, line 57; error : Argument 1 of instuction ‘selp’: must be register
ptxas application ptx input, line 57; error : Argument 2 of instuction ‘selp’: must be register
ptxas fatal : Ptx assembly aborted due to errors
error : Ptx compilation failed: gpu=‘sm_13’, device code=‘anonymous_jit_identity’
: Retrieving binary for ‘anonymous_jit_identity’, for gpu=‘sm_13’, usage mode=’’
: Considering profile ‘compute_10’ for gpu=‘sm_13’ in ‘anonymous_jit_identity’
: Control flags for ‘anonymous_jit_identity’ disable search path
: Ptx binary found for ‘anonymous_jit_identity’, architecture=‘compute_10’
: Ptx compilation for ‘anonymous_jit_identity’, for gpu=‘sm_13’, ocg options=’’
My kernel :
Code:
#define TYPE short
__kernel void threshold(__global const TYPE *inputBuffer, __global TYPE *outputBuffer, const TYPE insideValue, const TYPE outsideValue, const TYPE thresholdHighValue, const TYPE thresholdLowValue)
{
int location = get_global_id(0);
TYPE pixel ;
if(inputBuffer[location] < thresholdHighValue && inputBuffer[location] > thresholdLowValue)
{
pixel = insideValue; // works if pixel =1000
}
else
{
pixel = outsideValue;
}
outputBuffer[location] = pixel;
}
The following codes work if pixel value is static:
Code:
if(inputBuffer[location] < thresholdHighValue && inputBuffer[location] > thresholdLowValue)
{
pixel = 1000;
}
else
{
pixel = 0;
}
Code:
if(inputBuffer[location] < thresholdHighValue && inputBuffer[location] > thresholdLowValue)
{
pixel = insideValue;
}
else
{
pixel = 0;
}
Code:
if(inputBuffer[location] < thresholdHighValue && inputBuffer[location] > thresholdLowValue)
{
pixel = 1000;
}
else
{
pixel = outsideValue;
}
, but not with both, insideValue, outsideValue together.
Every part of code for “insideValue, outsideValue, thresholdHighValue, thresholdLowValue” are the same and all values are read well before sending to GPU.
GPU : GTX 285
Did you have any idea on this issue.
Thanks.
