Hi All,

 

I installed my new redaon hd4870 1Gb and tested the sdk exemple, ans they seems to work fine.

 

I then installed acml-gpu and gcc 4.1.2.

 

my code is as follow :

#include "acml.h"
#include <stdlib.h>

main(){

    float *fA,*fB,*fC;

    fA = (float*)malloc(i*i*sizeof(float));
    fB = (float*)malloc(i*i*sizeof(float));
    fC = (float*)malloc(i*i*sizeof(float));

   ->FILL fa and fb

    sgemm('N', 'N', i, i, i, 1.0, fA, i, fB, i, 0.0, fC, i);

    free(fA);
    free(fB);
    free(fC);

}

 

I compile this :

gcc run.cxx -I/opt/ati/acmlg1.0/gfortran64/include -L/opt/ati/acmlg1.0/gfortran64/lib -lacml -lacml_mv -L. -lgfortran -lCALBLAS -laticalcl -laticalrt -lm -lg2c

The execution gives the following :

ERROR: unable to allocate minimum uncached system (GART) memory

Does anyone have any idea/suggestion ?

 

thanks
