\fBsysdata\fR - find basic hardware system data
9
After the \fBatlc\fR package is built, a small benchmark is run as part of the testing procedure. This benchmark
10
tries to get some information about the hardware. The program \fBsysdata\fR displays the same hardware information
11
that the benchmark will display, but runs in a fraction of a second, whereas the benchmark can take from 19 s
12
(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
13
arguments to \fBsysdata\fR
15
The information gathered on hardware and software both developed by the same company (i.e. Solaris on Suns, AIX
16
on IBM RS/6000, IRIX on SGI, ... etc etc) is generally more informative than the free systems (Linux, NetBSD,
17
OpenBSD, FreeBSD) where it is usually impossible to get much hardware information.
19
Here are some examples of the use of \fBsysdata\fR on a number of systems. The large number of examples is for
20
my own use as much as anything, so I can keep track of the development of sysdata and see easily where it needs
21
extending. Examples are presented for:
24
1) Sun Ultra 80 running Solaris 9
26
2) HP C3000 running HP-UX 11
28
3) SGI Octane running IRIX 6.5.16
30
4) IBM RS/6000 running AIX 5.2
32
5) Dec Alpha 600a Personal Workstation running Tru64 5.1B
34
6) Cray Y-MP running UNICOS 9
36
7) Sun SPARCstation 20 running NetBSD 1.6
38
8) Sun SPARCstation 20 running OpenBSD 3.2
40
9) Sun SPARCstation 20 running Debian Linux
42
10) Sun SPARCstation 20 running Solaris 2.5
44
11) Generic PC with 350 MHz Pentium II running Redhat Linux 7.2

Here's the output from \fBsysdata\fR 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
123
reported at not the R10000 and R10010 that are reported by SGI's hinv. \fBsysdata\fR is not meant to replace other
124
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
277
hardware. The following are free UNIX versions. In these cases the data gathered is never as complete. In
278
particular the amoumt of memory reported if often less than the real amount due to memory taken by the
279
operating system (kernel etc). The number of processors the system can support is never available.
281
Here's the first such non-commercial UNIX from a single processor Sun SPARCstation 20 running NetBSD 1.6.

Here's data from a Sun SPARCstation 20 running OpenBSD 3.2. The machine has 320 Mb of RAM, not 318 Mb as
320
indicated. The number of processors the system supports is reported as unknown, but should the system have been
321
running Solaris 9, as in the example 1 (sparrow), then this information would have
322
been determined, but it is not available under OpenBSD - or Solaris 2.5 for that matter.

The next machine is a Sun SPARCstation 20 running Debian Linux. The version of Debian is unknown, but clearly

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
399
reported. The number of processors the system supports is reported as unknown, but should the system have been
400
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.
