Wrote on the subject of O300 noise reduction hack at May 23, 2008, 5 a.m...

I've got an O300 in a rack in the lab at work. We don't have a dedicated server room and the noise level was driving people crazy. So I decided to replace the fans. The original chassis fans are NMB Minebea 3110KL-04W-B79 and run at a fixed speed of > 4000 RPM. Sound pressure is 40dB a piece. There are four chassis fans plus one in the PSU.

The problem is that the L1 has a lower warning limit of 2160RPM, and most silent fans are below that. I opted for Scythe / NMB 3110KL-04W-B39-E51 fans running at 2700RPM (28dB a piece): http://www.scythe-usa.com/product/acc/0 ... etail.html

Replacing the chassis fans was easy, the PSU fan was more of a problem because the entire thing had to be disassembled. Inside was a crappy delta fan, is was so poorly balanced you could feel the fan shake if you spun it.

Here's what the L1 has to say now:

Success, and much more quiet! Oh, we don't have air conditioning either so this is a normal temperature.

It looks like SGI had the same idea. In Neko's O350 the fans run at 2300 RPM, with the same 2160RPM warning limit.

Now this is a deep dark secret, so everybody keep it quiet

Wrote on the subject of SGI Cube Demo reloaded at Aug. 3, 2008, 3:54 a.m...

I've got R8000 optimized math libraries (ATLAS), see this thread . There's a newer version of ATLAS, but so far I've only used it on Origin 300 systems.

You have to think of ATLAS as a building block for math and engineering apps; there's a clone of Mathlab that uses it for example. The PowerIndigo2 was always positioned as a pocket size number cruncher, so somehow this class of software suites it, I think.

I can't speak to the Indigo2, but my Octane MXE runs 1680x1050 great.

Hmm. But is it worth it? If you crank up the resolution, more memory is needed for the framebuffer, at the cost of buffers for OpenGL features. I know MaxImpact / MXI / MXE can do 1600x1200, but you loose the Z-buffer, which essentially tuns your graphics card into a glorified 2D framebuffer.

I'm curious what 'glxinfo' has to say about your 1680x1050 mode.

OK, seems there are some modes with decent RGB depth, Z ('db') and even alpha available. Good to know.

IRIX 6.1 was only for R8000 Power Challenge/Onyx and Power Indigo2. IRIX 6.2 was an all-platform release again.

To accentuate the special identity of the IRIS 4D/70, Silicon Graphics' designers selected a new color palette. The machine's coating blends dark grey, raspberry and beige colors into a pleasing harmony. ( IRIS 4D/70 Superworkstation Technical Report )

The buyer is adjusting his bid, probably afraid to be sniped in the last second. The seller however, is from Sweden, has zero feedback and posted to Ebay US (or at least that's where I found this one). I can imagine some people's hesitation to bid on it, and Mr. Roberto T. got lucky.

The world will end in 2038. Or at least, 32bits time_t (seconds since 1/1/1970) will overflow.

IRIX isn't 64 bit on all SGIs.
64 bit IRIX advertises itself as IRIX64 in uname (possibly with some parameters).

Correct.

Indigo, Indy, Indigo2 and O2 (any CPU) all ran 32bit versions of the OS.

Most R10K and above machines run IRIX64 (Octane, Octane2, Fuel, Tezro).

Not sure what happens on an R10K I2.

64bit. R8000 Indigo2 as well.

Onyx/Challenge always runs a 64bit kernel, even is it has R4x00 CPUs. If you run IRIX 6.x on it, at least. If you run IRIX 5.x on it, is will be 32bits, because IRIX 5 wasn't 64bit at all.

There's a program named 'midb' that does exactly this, but works for older IRIX releases. I think I dug it up as a shar file from the comp.sys.sgi archives, but who knows ...

I'd like to reverse engineer the product descriptor file once, then I could write my own gendist. This is relevant for pre-IRIX5.3 systems, for which this utility was never released.

Wrote on the subject of Alternative SCSI DVD-ROM - Boots IRIX + Audio-over-SCSI at Jan. 4, 2009, 11:04 a.m...

So, I dug it up. Mine is a Pioneer DVD-305S, a SCSI 10x/40x DVD-ROM in the usual form factor with a 50pin scsi connector. I set the 512byte blocksize jumper.

: DVD-A05SZ.jpg (8.5 KiB) Viewed 2443 times

I attached it to an Indy running IRIX 6.2. The Indy will boot from an original IRIX CD just fine (I didn't try audio).

IRIX reports:

Code: Select all


# scsicontrol -i /dev/scsi/sc0d6l0


/dev/scsi/sc0d6l0:  CD-ROM        PIONEER DVD-ROM DVD-305 1.03


ANSI vers 2, ISO ver: 0, ECMA ver: 0;


Response format type 1, but has SCSI-2 capability bits set


supports:  synch linkedcmds.  inquiry format is SCSI 1


Device is  ready

But, and this is where it gets interesting: it also boots IRIX DVDs . Yes, and that's no a typo!

First, I used a PC with Nero to burn a 'dd' image of an IRIX 5.3 CD to a DVD. This boots just fine, just a lot quicker than you're used to from 'Indy vintage' external CD-ROMs :-)

Encouraged by this initial success, I added a second (4.5GB) disk to my PowerIndigo2 and 'dd'-ed the first IRIX 6.2 CD onto it. I then used fx to grow the partition to the size of the actual harddisk, changed the partition type back to 'sysv' (?) and used growfs to grow the EFS filesystem. Next, I copied the second IRIX 6.2 CD into this filesystem, unmounted it and 'dd'-ed the entire harddisk to my server where I burned it to a DVD.

This boots too!

IRIX reports:

Code: Select all


# df -k


Filesystem             Type  kbytes     use     avail  %use Mounted on


/dev/root               xfs  4329525  1306802  3022723  31  /


/dev/dsk/dks0d6s7       efs  4410288   805355  3604933  19  /CDROM

As far as IRIX is concerned, this is just a very large CD-ROM. And it seems it doesn't care, as long as the device utilizes a 512byte block size. Somehow, this was to be expected since you can perform similar hacks using a harddisk.

I am quite excited. Imagine an entire IRIX distro including all patches etc. on one or two DVDs. I've only used systems and software from well before the DVD was invented so this hack is completely transparent

Oh, there are some thing that don't work:
* UFS. This would require modifications to IRIX. Think of this as a large EFS CD-ROM
* DVD video. Ditto.
* You may need IRIX 6.2 to make one, I believe IRIX 6.5 has read-only EFS support
* My PowerSeries doesn't want to boot from the Pioneer, either from a CD or DVD. I tried with the 4D/440VGX which has PROMs that are new enough that they recognize a CDROM (doesn't need those 'I'm a harddisk' hacks).
* I didn't try dual layer DVD, and I don't even know if the Pioneer supports them. There's an upper limit of 8GB to EFS filesystems.

Have fun

I'm afraid it goes a little beyond environmental monitoring. Remember that blue Fuel prototype I've got here? It's got old L1 firmware. I don't really care, but it was complaining about it at startup so I thought I'd fix that. Did that, and it was dead .

Hooked up an L1 serial cable, got L1 prompt (phew!), did 'pwr up' and, I kid you not, it said something along the lines of "No suitable power supply found".

I rebooted the L1 in the alternative flash bank and everything worked again. Lesson learned: there's some sort of ID in the PSU to identify it to the L1 via i2c or similar and without it you get nothing. You need a real Fuel PSU.

Indeed, and it also beats the R7K/600 in many cases, but again it varies. For code compilation, the R7K/600 is faster than R12K/400 when using GCC, but the R12K is faster when using MIPS Pro. Can't comment much beyond this, not enough data yet.

Easy. No released GCC version knows how to schedule instructions for R10k class CPUs. This will change with GCC 4.4, btw. So, GCC compiled code is optimized for R4x00 class CPUs and the R5k/R7k are architecturally closer to an R4k than an R10k or R12k is.

When you use MIPSpro, I assume you build optimized binaries for each CPU?

OK, so it's about the execution speed of the compiler itself.

GCC itself is compiled with GCC. GCC schedules instructions for an R4x00. Therefore the GCC binaries themselves don't take advantage of improvements in R10k class processors.

MIPSpro can schedule code for various CPUs, or at least use a model that doesn't work too bad on the various MIPS CPUs out there. I don't know what flags SGI used when they built MIPSpro, but I doubt that they optimized the binaries exclusively for R4x00.

R10000 and up support speculative, out of order execution. This is a completely different animal as far as a compiler is concerned. R5000 and R7000 don't do any of this and are architecturally closer to R4x00 class CPU's even if they support the MIPS4 instruction set.

GCC also knows about R5K/R7K, which is why it runs better on such systems.

GCC can target those CPUs, but the GCC binaries themselves are built without target specific flags (just '-O2 -g') and therefore default to R4x000 (that's simply the default target for GCC). If they run (relatively) faster on a certain CPU, it is because that CPU is architecturally closer to an R4k than some other CPU.

If you would want to make GCC itself run as fast as possible on these CPUs, you would have to rebuild GCC with different CFLAGS in the Makefiles. There are other ways to squeeze more speed out of GCC itself, such as profile based feedback bootstrap builds (profiledbootstrap). I do regular bootstrap builds and regression testing of GCC -- I'll see if I can do an R10k profile-optimized bootstrap of a GCC 4.4 snapshot. See if it does much for the speed of GCC itself.

You might be surprised. The compiler binaries installed on my Fuel are, as far as I can be bothered to check offhand, all MIPS3.
Infact, /usr/bin/driver is MIPS2.

Ian.

ABI has everything to do with the available instruction set, but nothing with scheduling of the instruction mix.
Scheduling instructions is trying to keep all execution units of the CPU busy at all times, so it's very target CPU dependent.

I can tell MIPSpro (with -r10000 -mips3') to schedule instructions such that it favors R10k, but use no instructions exclusively available on MIPS4 (so the resulting binary runs on R4k, but favors R10k). Yes, for that last drop of performance you would choose MIPS4. But, there are not many new instructions in MIPS4 over MIPS3 (some prefetching insns, and of course MADD which is irrelevant unless you're running floating point intensive code). Usually the performance benefits of using MIPS4 are not worth loosing compatibility with R4000 class systems, and thus SGI built almost everything MIPS3.

Oh, to make it even more confusing (?): R10k is an out-of-order CPU, so it can rearrange the instruction stream on the fly to a certain extent and would therefore be more tolerant to code optimized for a CPU other than itself. R8000 is an in-order CPU which is why it was so lousy at running contemporary (R4k optimized) code.

I'm not too fond of the Atlas series either. We used to have Quantum Atlas disks at work -- they all died and were replaced within warranty, many of them more than once. I had a Maxtor Atlas in my O2 -- too noisy. I bought it new, btw.

IMHO the biggest problem with most UW SCSI drives is that by now they're all at least 5 years old. A 5 year old disk that was used occasionally may be fine, but one that has been spinning in an array for 5 years: forget it. Bearings wear out and get noisy.

The FD bearings are more quiet and more durable, so I feel more confident to buy them second hand.

That's odd, maybe Ian could enlighten us a bit on this? I've never heard of 2GB O3K DIMMs. ( If they exist, I wonder if the limits could be overridden...)

I think someone here is confused between a 2GB memory kit and a 2GB DIMM . Memory has to be installed in pairs (kits).

Now this is a deep dark secret, so everybody keep it quiet

It turns out that when reset, the WD33C93 defaults to a SCSI ID of 0, and it was simpler to leave it that way... -- Dave Olson, in comp.sys.sgi

But I guess it means you're in the neighborhood often -- If you'd like to see a bit of SGI history, just PM me.

The checksum is called RV and besides the checksum istself, it is apparently used to pad the VPD to 96 bytes, so that you'll have to adjust the length of the RV field as well if you delete or add anything. The checksum itself is in the first payload byte, i.e. the second byte after RV, the first being the length. The checksum does not cover the clear text name of the device (e.g. "SGI Gigabit Ethernet Controller"), but everything after that, including the RV itself. The sum of all the bytes covered modulo 256 should be 0x00. I've used the shell code below to compute the checksum over the hexdump, this time just hex bytes with one space, no linebreaks etc.

Good stuff, thanks!

So who will be the first to take a greening Indy case and see if turns Blue ?

I was thinking of trying this on an Indigo external CDROM first. But I wonder what happens in the next 5 or 10 years with plastic that has been treated like this -- will it turn brittle? get yellow all over again?
