Computerhistorie: Linpackmetingen
Linpackmetingen
In de loop der tijd bepaalden we de relatieve CPU performance van de meeste computer systemen die wij bij TNO Waalsdorp gebruikten met LINPACK 100*100 en LINPACK 1000*1000. De onderstaande tabel geeft de resultaten:
| Computer | OS/Compiler | LINPACK N=100(Mflops) | LINPACK N=1000(Mflops) | Peak(Mflops) |
