firstprivate clause in OpenACC

Accelerated Computing HPC Compilers Legacy PGI Compilers

Hello,

I can not use firstprivate with a parallel clause.
This is the code:

for (i=0; i < size; i++){
   j = i;
   #pragma acc parallel loop copy(a[0:size*size]) firstprivate (j)
   for (j=i; j < size; j++){
      a[i] =a[j*size+i];
   }
}

An the output from PGI (12.5) compiler:

[ivan@garoe testcase]$ make
pgcc -fast -Minline -Minfo:all -Mcuda -acc -ta:nvidia lud_acc.c -o lud
PGC-S-0036-Syntax error: Recovery attempted by inserting before identifier firstprivate (lud_acc.c: 20)

I have tried with this syntax too:

for (i=0; i < size; i++){
   #pragma acc parallel copy(a[0:size*size]) firstprivate (j)
   #pragma acc loop independent
   for (j=i; j < size; j++){
      a[i] =a[j*size+i];
   }
}

But I get some problems as well:

PGC-S-0035-Syntax error: Recovery attempted by replacing identifier firstprivate by accparallel (lud_acc.c: 20)

Does anyone has any idea about how to use firstprivate?

Thanks in advance for your time and assintance.

Support for the firstprivate clause will not be available until the 12.6 release.
