Any good tips on dissassembling a TRAM? (I've got access to a microscope, plus SMT tools *glances to the right*)
gotcha... will have to give that a spin.
Just tried running it on an Octane R12k-300 with MXE, though I haven't tweaked much (pretty much default config). Seems to be pretty slow with a lot of textures and ground objects, but tweaked it'd probably run OK. Without a lot of clutter it seemed to run pretty good... hate to compare it with this box (Athlon 2.4, overclocked). And I suspect that I've got the texturing set wrong too.

Now about those holes in the ground...
I tried running MXE and SI+TRAM and although everything booted up, there was horrible problems with texture rendering - seems Irix only likes TRAM on one head. Lots of stuff was broken, and didn't work at all... removing the TRAM from the SI card fixed it all.
This was with Irix 6.5.18f...

there was just a lot of things that didn't run. I don't think there is any particular reason (other than heat) to prevent it from working. But as a for instance, Mplayer did not want to run correctly before the second texture memory was removed - after that it did proper hardware scaling on the MXE, software on the SI, no problems at all.
How much 'better' is V6 over a stock MXI (which is what I have now)
The MIPS CPU architecture is a pretty awesome piece of engineering when programmed correctly - this just goes to show it!
Any thoughts on performance? I'd consider if it provides a huge benefit over MXI, but since MXI does texturing (plus I also have a spare MXI) and offers decent 3D speed, good 2D speed, and leaves open the possibility of PVO, I'd have to be convinced.

:)
So basically a V6 is really a [email protected] beast then... if you can run it at that speed, then you're good to go.
crap - I have a Samsung Syncmaster 700NF (with the BNC connectors) and was planning on possibly using that - but it looks like at 1280x1024 it only goes up to 89 Hz - though I haven't been able to determine that absolutely as the marketing material is verrah verrah vague.
LOL - I'm having the exact same problem as we speak...
I don't drink much, but kinda partial to good Appleton Jamaica rum, the older the better :D
try this one...

mind you I haven't played for a couple of years or so, due to not having time and trying to make ends meet... oh the gravy days of the tech boom :(

while looking for this pic, here's a couple of others I found of a light-modded O2 I have here:

I set a can down on my Octane dual-300 keyboard 'enter' key the other night by accident and inadvertantly opened about 40-50 copies of RealPlayer, which all chimed perfectly and loudly without so much as a hiccup - the thought that went through my head was "Try *that* on a PC"
I can't seem to get xscreensaver-getimage-file to work... I have images in the directory that .xscreensaver points to, but no dice.

Is there a trick that I'm missing?
SGI's 'swmanager' is the *only* package manager that I've found that can let you downgrade a whole OS a few notches, and not break very much, if anything at all. Apt-get, I've had dependency hell with in the past, and if you read the instructions, even *they* say that sometimes it's just easier to reformat and start again if you get into trouble.

I do believe the correct phrase is "When Satan skates into work"
Couple of thoughts...

The box looks quite baddass, but that's what you expect from SGI.

Dual Itaniums on the desktop sounds pretty cool, but I'd like to see some real bandwidth numbers on the various subsystems to see if the engineers at SGI are earning their T-shirts. This may actually be the case.

The next thought is that if they've designed things right, and if they can run the 'same' software across the whole Prism line, then that's pretty cool. To think that up until 6.5.22 if you ordered a base install set for your Indigo and your buddy ordered a base install set for his 128 processor Origin, that you both got the same box of disks was pretty cool. And you could basically run the same software on both (barring MIPS3/MIPS4 issues).

And at that point, basic compatibility across the entire line makes the $8500 base price pretty palateable, particularly if you use the 'big' iron to run the analysis, and the desksides to build the apps and fine tune them.

And if one showed up at my door tomorrow, I'd use it :D
Any thoughts on getting an R4k optimized SETIi binary compiled? I've been running the client on my Indigo, and it's taking longer to process work units than I think it should ( though I could be wrong... )
the BOINC version... I did a bit of a preliminary calculation, based on measured integer and FP MIPS:

Code: Select all

R12k-400 O2: FP - 405.53, INT - 418.91, TURN - 0.89 days

Total MIPS per unit: FP - 31,183,635  INT - 32,212,503

R12k-340 Octane (one thread of a dual CPU): FP - 345.38, INT - 358.04, TURN - 1 day

Total MIPS per unit: FP - 29,840,832  INT - 30,934,656

R4k-160 Indigo: FP - 59.8, INT - 96.55, TURN - 3.86 days

Total MIPS per unit: FP - 19,943,539  INT - 32,199,811



This was done by taking measured float and integer MIPS, multiplying it by the average number of days ( * 24 * 60 * 60 ) and tabulating the results. VERY unscientific, so I make no claims on it's validity. There's a good chance that the client is probably OK anyways - but it's interesting to note that the Indigo runs (if you compare integer speed) 3.71 times slower than the R12k-340, and takes 3.86 times longer to process the data. This data is also probably skewed by turnaround times anyways - as there's probably much interaction with cached data stores etc.

But just wondering if the client was in fact R4k optimized...
My dual-350 Octane is really quite competitive, work-unit wise.
I hear ya bro...
You bring the sack, I'll bring the bricks...
I think what you may have to do is that if you're going to run a bunch of units, once you get the machine registered tell it to download 5 or 10 days of work at a time, so even if only 5% of the requests go in, it always has fresh data in the cache.
Actually, you do it on the Seti website, you assign 'classifications' for your different machines once registered, and define operating profiles. The next time the client connects, it will update preferences automatically.

(though this will fall through to the Boinc site proper)

You can also turn off the 'Suspend if not idle' behaviour this way too.
Just hit 100k on my ongoing "Seti at Home" computation project. :) :) :)

For those that aren't following Team Nekochan on BOINC, currently we're ranked 415 of 35,661 teams. And I'm ranked 372 of 17,524 Canadian SETI hosts.

Everyone should run Seti on at least one machine, help get our team into the top 250 overall. Even my old trusty Indigo R4400 has run units with a total credit of 1832 since June 20th, 2005.

Hey, looks like someone just brought another 8 x 250 MHz Origin 2000 on-line!

Ontario's not that far behind. If I ever decided to give up computers and go into 'agriculture', I bet my electricity bills wouldn't move a lot either way - heh. My worst bill from last year was over $750, though I think that was 4 months worth. I wish they'd just do monthly billing, and keep the 'suprise' factor down.

It's not even so much that the electricity itself is expensive, but by the time you stick on the 'add-ons' it basically doubles the price (or more) from market value.

Ya know, paper is usually taller than wide ... I wonder how we got into the habit of working on monitors that are the opposite ?


Probably moreso due to old film formats than anything else - originally TV screens were round but quickly morphed to a 'filmy' aspect ratio. Also you don't fold open a pair of TV's like a book (which evolved from stuff like scrolls), though I bet if you did a survey here there are likely a lot of people only missing the 'folding' part. :D

I remember being very young, and visiting someones place that had one of those huge Beta decks with the turret tuner on the front. This was pretty much before video rentals started to take off, and wondered why they only had about 5 movies in their 'library' including one called 'Cleaning tape', after all even as a young'un it just seemed if you were going to spend a bazillion dollars on a VCR, buying a bunch of movies was a must. But apparently, I actually was right....

Your best bet is a Phobos G130, works fine in Indy and gives you a full duplex 10/100 separate from the built-in one. It also works in an Indigo. They show up on eBay for decent prices quite often.

When I was messing around with striping Clariion arrays, if I disconnected the primary loop, the automatic failover to the secondary loop didn't happen for what seemed like a minute or so, certainly 30 seconds. One might presume that at a low level the FC-AL protocol is the layer that fights for the connection, and is one addition that regular SCSI doesn't have. So long as the loop can re-establish itself, it can then start queueing/unqueuing the regular SCSI traffic without disrupting the overlying protocols, and should work fine.

You know, it sounds like these monitoring boards can probably be fixed... judging by what Oskar posted earlier, looks like it may be capacitors or something oscillating in the buffer amps. Anyone got a really good clear picture (IC part number readability is good) of what one looks like, working or not?

Actually I've used quite a few Sparkle (Fortron) PSU's here for PC kit, they're really pretty good quality for the price and seem to OEM a lot of the more 'popular' units. Once stripped an Antec PSU apart, lo, it was a Sparkle inside...

Hamei sent me some pics of the Fuel motherboard, and it looks like environment monitoring is done with a couple of Dallas DS1780 chips which provide monitoring for 10 voltages per chip. I'd guess that the chip beside the L1 serial connector is likely related to PIMM voltages, and the one next to the power supply (right next to the "Timekeeper Snaphat" chip in the corner) monitors power supply voltages. Since the chips 'read' OK, one can assume that either the analog input to the chip on the offending line is bad (implying a chip problem), the voltage reference for the device is bad, or the origin for the derived voltage is bad.

Anyone know for certain if only the 1.5V line has the voltage problem?

Looks like replacement chips are available. If someone with a *new* motherboard can take a picture of the board around the DS1780 near the Timekeeper chip that would be useful.

If it was software-only, as Joerg points out, SGI would have just reflashed the boards and saved the time and cost of replacing them. There has to be a hardware funky on the board that causes the monitoring to die over time.

Again, if someone with a 'new' Fuel mobo can take a picture around the 'Timekeeping Snaphat' chip (should be next to power supply stuff and the Dallas chip) I can do a comparison with the 'old' boards. Maybe it's just a faulty run of Dallas chips, who knows?
