The Mach3* <BR> microkernel was ported first, followed by the Linux* 2.2.0 kernel, and <BR> these have helped track the overall health of the Itanium RTL model <BR> for the last two years. These operating system (OS) kernels also <BR> helped pre-silicon performance analysis and compiler-generated code <BR> analysis." <BR> <BR> "The Mach3 kernel (the IA-64 port was called Munster internally) was <BR> ported because it contained features similar to Microsoft Windows NT*, <BR> such as tasks, threads, interprocess communication (IPC), and <BR> symmetric multiprocessing (SMP). Mach3* allowed us to exercise parts <BR> of the Itanium model in a similar way to Microsoft Windows NT, but at <BR> a reduced scale and without device support." <BR> <BR> "Linux (the IA-64 port was called IPD-Linux internally) was ported <BR> because its source is readily available and 64-bit clean, it is highly <BR> configurable, and it would exercise the model in a different way than <BR> Mach3. We started with a released 2.2.0 version of the source and <BR> ported the kernel using a non-GNU C Compiler (GCC). The difficulty of <BR> porting the Linux kernel without GCC made the task more challenging." <BR> <BR>========== End ================= <BR>-- <BR>|======================+========================+====================| <BR>| 以无法为有法 , | 拳本无法,有法也空; | 我爱GNU/Linux, | <BR>| 以无限为有限 | 一法不立,无法不容。| 因为我爱自由! | <BR>| | | | <BR>| 截拳道宗师-李小龙 | 意拳宗师-王芗斋 | 土人 Linuxrat | <BR>|======================+========================+====================| <BR> <BR>※ 来源:·BBS 水木清华站 smth.org·[FROM: 202.112.168.253] <BR><CENTER><H1>BBS水木清华站∶精华区</H1></CENTER></BODY></HTML>
