cufft using pgi compiler

Can I call cufft using pgi compiler?

My code is:

#include <stdio.h>
#include <math.h>
#include <cuda.h>
#include <cuda_runtime.h>
#include <cufft.h>

#define NX 1200
#define NY 1200

int main(int argc, char *argv)
{
cufftHandle plan;
cufftComplex devPtr;
cufftComplex data[NX
NY];
int i;
struct timeval t1,t2,t3,t4;
long c_fft,c_all;

/* source data creation /
for(i= 0 ; i < NX
NY ; i++){
data_.x = 1.0f;
data.y = 1.0f;
}

gettimeofday(&t1,NULL);

/* GPU memory allocation /
cudaMalloc((void
*)&devPtr, sizeof(cufftComplex)NXNY);

/* transfer to GPU memory /
cudaMemcpy(devPtr, data, sizeof(cufftComplex)NXNY, cudaMemcpyHostToDevice);

gettimeofday(&t2,NULL);

/
creates 2D FFT plan /
cufftPlan2d(&plan, NX, NY, CUFFT_C2C);

/
executes FFT processes /
cufftExecC2C(plan, devPtr, devPtr, CUFFT_FORWARD);

/
executes FFT processes (inverse transformation) */
cufftExecC2C(plan, devPtr, devPtr, CUFFT_INVERSE);

gettimeofday(&t3,NULL);
c_fft=(t3.tv_sec-t2.tv_sec)1000000+(t3.tv_usec-t2.tv_usec);

/
transfer results from GPU memory /
cudaMemcpy(data, devPtr, sizeof(cufftComplex)NXNY, cudaMemcpyDeviceToHost);

/
deletes CUFFT plan /
cufftDestroy(plan);

/
frees GPU memory /
cudaFree(devPtr);

gettimeofday(&t4,NULL);
c_all=(t4.tv_sec-t1.tv_sec)1000000+(t4.tv_usec-t1.tv_usec);

printf("%13ld microseconds for fft\n",c_fft);
printf("%13ld microseconds for all\n",c_all);

/
for(i = 0 ; i < NX
NY ; i++){
printf(“data[%d] %f %f\n”, i, data.x, data.y);
}
*/

return 0;
}


I compiled with “pgcc -I /opt/pgi/linux86-64/10.2/cuda/include/ -L /usr/local/cuda/lib/ fft2d.c -lcufft” and got the error message like this:
PGC-F-0249-#error – — !!! UNSUPPORTED COMPILER !!! — (/opt/pgi/linux86-64/10.2/cuda/include/host_defines.h: 41)
PGC/x86-64 Linux 10.2-0: compilation aborted

This code works with “gcc -I /usr/local/cuda/include/ -L /usr/local/cuda/lib/ fft2d.c -lcufft”

Could anyone suggest what I can do to solve fft using the pgi compiler?

Thank you._

Hi nutty,

While we have the rights to redistribute NVIDIA’s CUDA header files, we don’t have the right to modify them. Hence, we aren’t allowed to remove the “#if !defined(GNUC)” guard nor port the headers to work around the GNU specific C constructs.

It’s possible that this will change in the future, for now you’ll need to use gcc or nvcc to compile this code.

Sorry,
Mat
