16.2. parloop statement

Example 16-4. Example:

parloop
   c::=clusters!;
do
   ...
end

Example 16-5. The parloop statement is syntactic sugar to make convenient a common parallel programming idiom.

parloop
   S1
do
   S2
end;

is syntactic sugar for:

par
   loop
      S1
      fork
         S2
      end;
   end;
end;

Example 16-6. This code applies 'frobnify' using a separate thread for each element of an array.

par
   loop
      e::= a.elt!;
      fork
         e.frobnify;
      end;
   end
end

Example 16-7. Using the parloop shorthand, the same code could also be written:

parloop
   e: := a.elt!;
do
   e.frobnify;
end;
