However, I don't believe much about TSCP's results because this program is quite small and simple, comparing with so-so chess engines. Some results of TSCP differ from ones of others. For example, TSCP can run faster on some Intel CPU than equivalent AMD. Thus, do you have comparations between compilers for other engines, say Crafty? > >The Intel compiler is also available to students for (I think) $30.
