[R] Open source project that needs performance optimizations

I am not up on the internals of R but there does seem some run for 
parallelism. Are we talking about special hardware? or running this on 
an Intel Box? If it is the second, then I am thinking threads would be 
the way to go. Please consider the following
R statements:
     for( i in 1:30 )    a[i] = f1(i)
Would it make sense to  setup a separate thread for each call to f1?  I 
think it in most cases, the answer is no but on some machines and 
depending on the running time of f1, it could be a big win. Also, does 
the user have to change his code, or would R be
smart enough to do the work behind the scenes. I consider the second to 
be significantly better than the first.
