the details of our hosts are:
HOSTS: snorkle (sunhost), tux (linhost), beastie (bsdhost) PROMPT: host [0] Solaris INFO: Solaris 10, x86 Linux INFO: CentOS 5.4, x86 FreeBSD INFO: FreeBSD 8.1, x86CPU information In Solaris:
To determine whether the kernel is 32bit or 64bit capable:
snorkle [0] /usr/bin/isainfo -kv 32-bit i386 kernel modulesDetails on the processor of our test host (snorkle):
snorkle [0] /usr/sbin/psrinfo -vp The physical processor has 1 virtual processor (0) x86 (AuthenticAMD family 15 model 47 step 0 clock 2187 MHz) AMD Athlon(tm) 64 Processor 3500+For comparison, below are the runs from a multicore host (Sun Fire
T2000) and a multiproc host (Sun SPARC Enterprise M5000):
solT2000 [0] /usr/sbin/psrinfo -vp The physical processor has 32 virtual processors (0-31) UltraSPARC-T1 (chipid 0, clock 1000 MHz) solM5000 [0] /usr/sbin/psrinfo -vp The physical processor has 4 virtual processors (0-3) SPARC64-VI (portid 1024 impl 0x6 ver 0x93 clock 2150 MHz) The physical processor has 4 virtual processors (8-11) SPARC64-VI (portid 1032 impl 0x6 ver 0x93 clock 2150 MHz) The physical processor has 4 virtual processors (16-19) SPARC64-VI (portid 1040 impl 0x6 ver 0x93 clock 2150 MHz) The physical processor has 4 virtual processors (24-27) SPARC64-VI (portid 1048 impl 0x6 ver 0x93 clock 2150 MHz)The 'prtdiag' utility can also list out the processors, virtual
or otherwise. As with the memory post, 'prtdiag' doesn't always
list out any usable information, so your mileage may vary:

To determine whether the kernel is 32bit or 64bit capable, unlike
Solaris which has a command, for Linux and FreeBSD we have to use
kind of a hack:

Linux, for FreeBSD we use a hack:
