Just do it the same way as in the writer, but read your data into your
"local copy" (was "a" in my writer example) and copy it to the distributed
array A. Note that this copying has to be done by all contexts, i.e.

if (Pooma::context() == 0)
  read into a (using a.engine().localEngine())
A(domain) = a;
