Could people please give me the output of the command:
/usr/sbin/psrinfo -pv | fgrep UltraSPARC
on a machine, and tell me what the machine is.
There is some code in the ATLAS maths library which does this:
if (!CmndOneLine(NULL, "/usr/sbin/psrinfo -pv | fgrep
UltraSPARC", res))
{
if (strstr(res, "UltraSPARC-IV"))
mach = SunUSIV;
else if (strstr(res, "UltraSPARC-III"))
mach = SunUSIII;
else if (strstr(res, "UltraSPARC-II"))
mach = SunUSII;
else if (strstr(res, "UltraSPARC-I"))
mach = SunUSI;
}
I would like to extend that, so cover other processors.
On a T5240 I have access to, I see:
/usr/sbin/psrinfo -pv | fgrep UltraSPARC
UltraSPARC-T2+ (chipid 0, clock 1167 MHz)
UltraSPARC-T2+ (chipid 1, clock 1167 MHz)
but can anyone else tell me what they get on other machines? I suspect
'T1' and 'T2' without the plus sign might be possible, but I don't
actually know.

I'd like this for Solaris x86 machines too, if someone can grep the
processor type. Obviously it wont be UltarSPARC in that case.

On our T1000s and T2000 running Solaris 10 I get:
UltraSPARC-T1 (cpuid 0 clock 1000 MHz)
Nice and slow :-)

Thank you. Obvious '-p' has been added in 9 or 10.
Is there any way you can get the processor type on that machine
For my own purposes, we are only intending supporting S10 or 11, but I
was hoping to passs the mods back up to the ATLAS developer, so he can
add support for later CPUs. That's going to need some work, if the
command he uses (/usr/sbin/psrinfo -pv) does not work on Solaris 8.

Thank you.
That was particularly what I was looking for. I guess there will be a T2
too. a T3 is in development I'm aware of that, if some Sun blogs are
anything to go by.
> Nice and slow :-)
Yes, these CoolThreads don't work too well for some applications. My
Blade 2000 (1200 MHz) is a *lot* quicker than the 1167 MHz T5240 for
most of what I'm doing with these machines.
But the T5240 leaves my blade well behind on some well written
multi-threaded code.
Andrew Gabriel posted some multi-threaded code
http://groups.google.co.uk/group/comp.unix.solaris/browse_thread/thread/7041af61bab6cfd/718b4fb647765119?hl=en&ie=UTF-8&q=Single-threaded+T5240+performance&pli=1
for computing the prime less than n. The performance on the T2 was
excellent.
We do in fact have an algorithm for computing prime_pi() which is much
more sophisticated that the one used in that example code Andrew posted.
It should leave Mathematica for dead, and when converted into
multi-threaded, will be even quicker.
PS, if you are reading this Andrew, I noticed your comment about the use
of FORTRAN style variables in C code in that thread above.
I once knew a PhD student whose variables were all Disney characters!! I
tried helping here debug her code, but it is almost impossible when
lengths are variables like Snoopy, an attenuation coefficient is Sleepy,
the scattering coefficient might be Snow_White etc.
(Sorry Louise, in the unlikely event you are reading this, but your use
of variables names were 'unique'. )

Thank you very much. I need to work out if the ATLAS code uses the same
bit of code for x86 as it does sparc, but these are useful to known
Does anyone have access to a machine running a T2, but not a T2+
processor? I'd particularly like to know what that gives, although I can
take a pretty good guess.

I used to work with graduate students at Princeton. Most of them hadn't
a clue about computers. Not surprising in the early 1980s; computers of
any sort cost more than I made in several years. If not for IBM's
generosity even Princeton would have had trouble affording them.
I tried to teach "The Art of Computer Programming" with varying degrees
of success. Among the hardest things to teach were the idea that
variable names should be selected for clarity; e.g. you wrote "PRESSURE"
instead of "XYZZY". Equally difficult was the idea that anyone else
might need to be able to read and understand their code. Inevitably the
students moved on and someone new had to figure out what they had been
doing and continue or modify/improve/continue.

The number of threads makes up for it a bit...
I didn't quite get how atlas uses the results, but it feels like it
might be better to try and munge the output of isainfo/isalist than
psrinfo. Check the man pages for what flags to use.

This is possibly apocryphal, but I heard of an electrical engineer who
#defined K in their C code just so they could write things like "10K"
in their program... :-(

I got my PhD in 1999 - I think she got hers about the same time. So not
as early, and computers were a lot more common then.

It's a bit silly to use names like that. I would have thought it was
common sence not to.

ATLAS is a linear algebra library which is very CPU intensive. To get
best peformance, the installation tunes various parameters to reduce the
executation time. That tuning process is taking 8.5 hours on the T5240.
It's possible to reduce this dramatically, but having a set of default
tuning parameters for any particular archititecture.
http://math-atlas.sourceforge.net/faq.html#ArchDef
I want to add support for the T1, T2, T2+, T3 (in development) and will
take a guess there might be a T3+, T4 and T4+. If the latter processors
never exist, it's only a few bytes wasted.
Once that is done, I can generate tuning parameters once on the T2+ and
reduce the build time of ATLAS considerably.
The defaults will change with compiler version, speed of processor etc,
but having a set that is half-reasonable will be useful.
You are probably right about using other techniques. I suspect the ATLAS
develpers are not Solaris gurus and do not have access to all SPARC
systems. (One at least does have access to the T5240 I used).

There's an example in K+R where an Algol programmer could write Algol
and the C compiler accept it, given a set of #define's. Each to their
own I guess.

Nod. It just seems more useful to check for CPU features
(isainfo/isalist) rather than CPU names (psrinfo). But this is probably
down the list after actually getting the thing to build at all :-)
How do they cope with x86 chips with their variety of CPU extensions
and SSE versions?

ATLAS does build, but it is only one of about 100 components of Sage.
The problem is the length of time ATLAS takes to build + tune. ATLAS is
probably taking 40% of the total build time. (8.5 hours for ATLAS on a
T5240). It takes a bit less on my Blade 2000 to build ATLAS (probably
4-5 hours). It should be possible to reduce both dramatically by
avoiding all this tuning.
There is an issue with ATLAS dumping core on the T5240, the reason for
which we don't know, but we have a work-around. (Basically return a
sensible default for one of the parameters, rather than try to get an
optmised value, which results in a core dump).
ATLAS build fines on my Blade 2000 - it just takes many hours to do so.

There is particular code written for particular processors for Linux. I
don't think there is much at all done for Solaris on x86, but I am not
sure.
There's currently no native windows port of Sage, though Microsoft are
sponsoring one.
My main interest is in the SPARC port of Sage. The OpenSolaris is
another issue, and I will address, but SPARC is my main priority. If I
can cut the build time of ATLAS a lot, quicker progress can be made on
other issues. Hence despite the fact ATLAS build, and other things like
ecl (lisp interpreter do not), I'd like to resolve the ATLAS issues first.

When I was teaching maintenance of a sonar system with an embedded
computer, I found in the schematics, that a button I had been taught
does nothing actually had a wire back to an interrupt input.
I asked the manufacturer's rep what that did, and he didn't know but
showed me where the assembly language source for the system was stored.
The jump labels looked like the graphics in the old Batman TV series:
Biff
Bang
Pow
boom
crash
etc.
I showed it to the rep. "Oh, that must be Bob's code.
He's not with us any more."

In a language where a Duration of 1.0 is one second, it can be
VERY useful to declare
Minute : constant Duration := 60.0;
Hour : constant Duration := 60.0 * Minute;
Day : constant Duration := 24.0 8 Hour;

I once had to look at a system where the programmers had heard of the
DoD "Ada mandate" but were not aware of how easy it was to get a waiver
when the situation justified.
So they wrote an Ada package containing subprograms which you could
insert into LISP to make it acceptable to an Ada compiler yet
still have it resemble the original LISP.
And another group that wrote a pre-processor that translated straight
LISP into functionally equivalent Ada.
Sorry, guys, you are developing in LISP, not Ada. Without a waiver,
the so-called mandate said DEVELOP in Ada, not develop in LISP and
convert to Ada.

UltraSPARC-IIIi ... on a V240 and V440
UltraSPARC-III+ ... on a V480 and 280R
UltraSPARC-IIe ... on a SunBlade 150, Netra X1 and SunFire V100
UltraSPARC-IIi ... on an Ultra5
All these should already be covered by the tests for UltraSPARC-II and
UltraSPARC-III that you listed (unless you need to differentiate
between, for example, a III, III+ and a IIIi).

Thank you. Currently the tests don't differentiate these, but there
might be some advantage to doing so. I'll discuss this with the main
ATLAS developer.
My immediate aim is to make the changes necessary to get ATLAS to build
in a reasonable time on the T5240. For that, I will make patches for
ATLAS inside Sage. I suspect the ATLAS developer will integrate my
patches for the newer processors once I've added the changes and
supplied him with the tuning data for at least a T2+.
He might be more reluctant to change code which has been tested for a
number of years, especially as we wont have the tuning data. Gathering
the data takes a long time and I don't have access to machines with all
these processors. I've personally got access to a Sun Ultra 60, Ultra
80, Blade 2000, Blade 2500 and T5240.
UltraSPARC-II .. Ultra 60 (Ultra 80 should be the same)
UltraSPARC-III+ .. Blade 2000
UltraSPARC-T2+ .. T5240
I don't know the output from a Blade 2500, but I can get that.

The code in Sage is aimed to be portable across many systems (M$ are
paying for a port to Windoze for example). Hence it's much preferable
for us to use the ATLAS code.

btw, rather than using system() try sysinfo()
For example, to pull the platform:
char larch[0x100];
if (sysinfo(SI_PLATFORM, larch, sizeof(larch)) > 0)
/* it worked */
larch will then contain a string like "SUNW,Sun-Fire-V210"
There are also SI_ISALIST, SI_MACHINE and various SI_ARCHITECTURE
ones..
