SAS 9.4 has parallel-processing feature in data step and other procs. Here is an example in data step.

   /* The following DATA step creates the input for the DS2 program. */
data in;

   do i = 1 to 1e8; /*5e8*/
   output;
end;
run;

proc means data=in sum;
var i;
run;

   /* This is the beginning of the DS2 program. */
proc ds2;
thread sumer / overwrite = yes encrypt=SAS;
drop i;
dcl double s;
   method run();
      set in;
      s + i;
   end;

   method term();
      output;
   end;
endthread;
run;

data ;
dcl double tot having format 16.0;
dcl double s having format 16.0;

dcl thread sumer s_inst;

   method run();
      set from s_inst threads=4;
      tot + s;
   end;
enddata;
run;
quit;

data _null_;
  set in end=end;
  s+i;
  if end then put s= 16.;
run;
