Table 1.
Comparison of SKT and GY timings (microseconds). L is the angular momentum of the functions, which have been chosen to be identical for the purposes of tabulation. The computer code was written in FORTRAN 95 and compiled with the Intel FORTRAN COMPILER Version 10.0 with the options -arch sse2 -tune pn4 -xN -static -O3, and timings were performed on an Intel Pentium 4 2.4 GHz processor with 512 kbytes of cache and 1 Gbyte of random access memory.
