sysdata - find basic hardware system data

sysdata
 

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.

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.
e.g. 1 (Sun Ultra 80 running Solaris 9)

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.

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
 
Release: 1.6

Nodename: blackbird
 
#CPUs supported: unknown
 
#CPUs online: 1
 
CPU type: rg:/autobuild/sparc/OBJ/autobuild/src/sys/arch/sparc/compile/GENERIC
 
FPU type: unknown

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

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

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
