Hello,

Just my notes:

1. SPARC Servers (a) - Sun SunFire V480 Server or higher requested. UltraSPARC 
T1 or higher are highly preferred.

2. Hosting (b,c) - There are a few organizations, ISVs, and academia that 
already host 'hundreds' of SPARC servers. 
3. Shipping - Not an issue for most real SPARC host providers and sponsors. 
They already have legacy and some modern hardware.

4. Support - Tongue in cheek, it is much easier to support existing SPARC 
hardware than 'off-the-shelf' PC hardware.
5. LiveCD/DVD SPARC distro - Existed through the Martux project for over EIGHT 
years. I have the older 0.1 Live DVDs >=Y2006.
6. SPARC emulators - See OpenSPARC project
7. Resources (human) - Illumos/OpenCSW/GSoC/etc? Host provider maintainer(s) 
can take care of most things.

Note on shipping: Mostly I see this as donating hardware to organizations and 
ISVs wanting to help and willing to contribute on a serious level to provide 
software on SPARC-based platforms. If I get some funding, I can 
install/rebuild/ship servers 'anywhere' in the world. 

Note on professional hosting solution providers/human resources: Most hosters 
provide automated Solaris administration tools and staff expertise allowing 
them to provide a comprehensive approach to managing business-critical Solaris 
environments.
 

Is the Illumos-based SPARC port healthy? Define your benchmarks of health. Now, 
modernization. The OpenSXCE SPARC distro can provide a more recent Illumos_gate 
b13e6c26bd03 kernel userland snapshot. A recent monthly snapshot is already 
included and can be updated through the project's repository. This can also 
become a weekly or nightly build of the distro (or on demand through web 
request) for personal development or bug testing purposes. A 'no fluff' 
snapshot version with just GRUB/GRUB2 bootloader and the Illumos kernel 
userland can be reviewed, tested, and discussed - keeping it simple.


With such talents from the key distro providers and key partners, SPARC 'may' 
be on the brink - but this is not the Titanic...
Also, keep in mind most ordinary developers/advocates don't have 
(1-8)x(4-16)-core x64-based workstations/servers either. Those eight physical 
x64-based CPU motherboards are still quite expensive for most people.... 

Hope that helps...

Subject: [developer] Status of SPARC
 
I'm sorry to open a thread that I'm sure will cause a lot of discussion most of 
which will probably be fruitless and pointless.  And yet, I feel compelled to 
do this.  Please think before you respond, and only reply if you have some 
thing useful to add to this conversation.

Recently, I advocated (as in RTI advocacy), a change to a program - kstat.  
After I integrated this change, another advocate pointed out that the SPARC 
port was broken by this otherwise worthwhile change.  In that particular 
instance, the advocate took it upon himself to fix the problem.

However, its clear to me that this particular advocate (Richard Lowe) may be 
the only advocate with regular access to SPARC.   Its also clear to me that the 
vast majority of ordinary developers lack such access to SPARC.

SPARC is on the brink.

There in the past have been numerous offers of SPARC hardware.  However, as far 
as I can see, these offers have come without any hosting, or even shipping to 
get the hardware to somewhere where it can be useful.

Historically, if a SPARC problem arose that broke the build, the change would 
be backed out.  Sun engineers were expected to build and test their changes on 
both architectures before integration.  illumos has never had this requirement, 
because we have always understood that most developers don't have SPARC access; 
but we have still tried hard to keep the SPARC port working.

Now the choice is not mine to make alone, but I'm going to strongly advocate 
that we simply stop making that effort unless sufficient SPARC resources are 
made available to keep the port "healthy".  The resources that we need:

a) Hardware - we need at least three fairly decent configurations (4 CPUs or 
better ideally) -- a build system for advocates, a build system open to all 
illumos developers, and a reservable "test" system.   (A sufficiently beefy 
system - e.g. a 12 way system, could be used to serve both of the build system 
needs, but I'd still prefer two separate boxes if possible.)  In the past there 
have been many people who have offered to donate -- in some cases pretty high 
end -- SPARC hardware to illumos.   We've failed to find a location for it 
though.

b) Rack space for the systems, with sufficient power, cooling, and network 
bandwidth for 24x7 operation.  We also need remote console access to all three 
systems, and ideally some kind of remote power control for at least the test 
system.  I think we should like to see a 12-month commitment to keep these 
things running; we don't want to go to the expense and trouble of setting them 
up only to find we have to vacate a few weeks later.  Recognize that two of 
these systems are going need very wide access to allow any illumos developer to 
have access.  (We'll do some basic validation of email addresses, and use 
public key SSH authentication, and we an even arrange for a "click to agree" 
legal agreement process before granting access.)

c) If "a" and "b" are not co-located, then funds to ship the servers to the 
hosting location.

d) Human resources (administrative) to perform basic system administration and 
setup of the above resources, including a calendaring system for managing the 
test reservations.  I *suspect* that this is the one resource we will find in 
plenty once the others are answered.  So please wait to reply to this until we 
see if a - c are forthcoming.

So, if we don't have these resources, and nobody is able to provide them, then 
I believe we don't have the resources to keep the SPARC port healthy, and I 
don't think we should continue to try.  In such a case, I'll recommend that we 
consider SPARC a secondary port, and not consider its functionality in deciding 
whether to integrate new changes or not.  (That said, I think we'll always be 
happy to accept fixes for SPARC from volunteers who submit them with 
documentation demonstrating that they have tested such fixes, but I imagine 
that SPARC support will quickly degenerate if we stop requiring SPARC 
functionality to work during the RTI process.)

I do know that some people have been working hard to get a viable SPARC 
distribution going.  My hat is off to those people.  I don't know if we yet 
have such a distribution.  I know no small level of effort has been invested 
there, and it is not my intention to denigrate that effort.

But even if everything worked perfectly for SPARC today, without the above 
resources I don't think we can truly consider the SPARC port healthy.  We need 
to be able to point developers at resources that they can use to fix and test 
their code for this platform.  Without that, its not fair or reasonable to 
insist that all changes be correct on SPARC. 

Nor is it fair or reasonable to ask the single RTI advocate (who by the way is 
also the only RTI advocate who doesn't get a paycheck for illumos related 
work!) to maintain this port all on his own.

In the past I tried be a middleman for this conversation -- it didn't work out 
so well.  Lots of offers for hardware came, but nobody with resources to host 
them, or an ability to ship hardware to the destination.  So instead I'm going 
invite folks to discuss and solve the problem here.   I think its more likely 
that a solution will come in an open forum.  And if a solution can't be found 
here, then it will be obvious to everyone, and hopefully nobody will think 
worse of us if we then decide to reduce our commitment to what will at that 
point be obviously an unsupportable platform.

(A brief note about simulators: there are some SPARC simulators.  I'm not aware 
that any of them are capable of running illumos.  If they were, it would be a 
huge boon to illumos and SPARC platform support.  However, because hardware 
frequently differs from emulation, I don't believe the existence of such a 
simulation eliminates the requirements I've stated here for a healthy port.  It 
*would* mean that there would be a reduced demand for the build systems, I 
think, and less frequent use of a remote test system, but I think we would 
still need these things to be available to the community to keep the port 
healthy.)

Thanks.
