Additional Notes:
Earlier submitted results for SPECclimate_MD with our SUN UE4000 were compiled with the Workshop 4.0 compiler with an optimization level of -O4 due to precision errors. With the newer Workshop 5.0 compiler does we can compile with -O5 which improves the performance by a factor of 4.
