NAME¶
sysdata - find basic hardware system data
SYNOPSIS¶
sysdata
DESCRIPTION¶
After the
atlc package is built, a small benchmark is run as part of the
testing procedure. This benchmark tries to get some information about the
hardware. The program
sysdata displays the same hardware information
that the benchmark will display, but runs in a fraction of a second, whereas
the benchmark can take from 19 s (quad 1.4 GHz Itainium 2 machine) to 14,906 s
(for a very old 33.3 MHz Cray Y-MP). There are no options or arguments to
sysdata
The information gathered on hardware and software both developed by the same
company (i.e. Solaris on Suns, AIX on IBM RS/6000, IRIX on SGI, ... etc etc)
is generally more informative than the free systems (Linux, NetBSD, OpenBSD,
FreeBSD) where it is usually impossible to get much hardware information.
EXAMPLES¶
Here are some examples of the use of
sysdata on a number of systems. The
large number of examples is for my own use as much as anything, so I can keep
track of the development of sysdata and see easily where it needs extending.
Examples are presented for:
1) Sun Ultra 80 running Solaris 9
2) HP C3000 running HP-UX 11
3) SGI Octane running IRIX 6.5.16
4) IBM RS/6000 running AIX 5.2
5) Dec Alpha 600a Personal Workstation running Tru64 5.1B
6) Cray Y-MP running UNICOS 9
7) Sun SPARCstation 20 running NetBSD 1.6
8) Sun SPARCstation 20 running OpenBSD 3.2
9) Sun SPARCstation 20 running Debian Linux
10) Sun SPARCstation 20 running Solaris 2.5
11) Generic PC with 350 MHz Pentium II running Redhat Linux 7.2
Here's the output from
sysdata on these 11 systems.

Here's another example this time on an SGI Octane R10000 with 2 x 195 MHz
processors. Note the CPU and FPU types reported at not the R10000 and R10010
that are reported by SGI's hinv.
sysdata is not meant to replace other
more sophisticated ways of obtaining system information (such as hinv on
IRIX), but its data is useful to record for benchmarking purposes.

Here's some data collected on a very old Cray Y-MP, which was introduced in
1991.
e.g 6 (Cray Y-MP running UNICOS)
Hardware provider: Cray
Hardware platform: Y-MP
Machine: CRAY_Y-MP
Sysname: sn5176

That is all the examples of commercial hardware running the operating systems
made by the manufacturers of the hardware. The following are free UNIX
versions. In these cases the data gathered is never as complete. In particular
the amoumt of memory reported if often less than the real amount due to memory
taken by the operating system (kernel etc). The number of processors the
system can support is never available.
Here's the first such non-commercial UNIX from a single processor Sun
SPARCstation 20 running NetBSD 1.6.
e.g. 7 (Sun SPARCstation 20 running NetBSD 1.6)
Hardware provider: unknown
Hardware platform: unknown
Machine: sparc
Sysname: NetBSD

L2 cache: unknown kb
Here's data from a Sun SPARCstation 20 running OpenBSD 3.2. The machine has 320
Mb of RAM, not 318 Mb as indicated. The number of processors the system
supports is reported as unknown, but should the system have been running
Solaris 9, as in the example 1 (sparrow), then this information would have
been determined, but it is not available under OpenBSD - or Solaris 2.5 for
that matter.
e.g. 8 (Sun SPARCstation 20 running OpenBSD 3.2)
Hardware provider: unknown
Hardware platform: unknown
Machine: sparc
Sysname: OpenBSD
Release: 3.2
Version: GENERIC#36
Nodename: crow.crow.localdomain

The next machine is a Sun SPARCstation 20 running Debian Linux. The version of
Debian is unknown, but clearly
sysdata is unable to determine this.
e.g. 9 (Sun SPARCstation 20 running Debian Linux)
Hardware provider: unknown
Hardware platform: unknown
Machine: sparc
Sysname: Linux
Release: 2.2.20

Here's data from a Sun SPARCstation 20 running Solaris 2.5 (SunOS 5.5). The
machine probably does have 352 Mb of RAM as reported. The number of processors
the system supports is reported as unknown, but should the system have been
running Solaris 9, as in the example 1 (sparrow), then this information would
have been determined, but it is not available under Solaris 2.5.
e.g. 10 (Sun SPARCstation 20 Solaris 2.5)
Hardware provider: Sun_Microsystems
Hardware platform: SUNW,SPARCstation-20
Machine: sun4m
Sysname: SunOS
Release: 5.5
