Dom testar ett FORTRAN program, det finns ingen fortran-kompilerare som > genererar G5-optimeringar �nnu. Det FINNS en C-kompilerare som g�r det. Enligt Veritest rapport det finns nog. I denna test anv�nde inte G5 optimeringar. > 2. Vektorisering testades inte p� n�gon av plattformarna (SSE2 eller Altivec). Inte d� platformar j�mf�rdes, en version som var handoptimerad med Altivec var testad och den var ca 10 g�nger snabbare �n utan optimeringen. -- Jussi Hagman CS in �bo Akademi University Studentbyn 4 D 33 juhagman@abo.fi 20540 �bo jhagman@infa.abo.fi Finland
