firefox has tag 0x100013, you have to tag your /usr/local/firefox/firefox (or whereever it lives):

Ditto for tbird, except the tag is 0x100031

What's wrong with "objdump --disassemble" or even "objdump --disassemble-all".
There are some "disassemblers" for Linux that are really just perl scripts that wrap around objdump. You may be able to adapt one for IRIX.

Also, there's "dis" on IRIX. Depending on the status of IRIX binary compatibility in Linux/MIPS, you may be able to run it.

NetBSD has IRIX compatibility. The article series is an excellent read: http://www.onlamp.com/pub/a/bsd/2002/08/08/irix.html

You may be right for non-x86 platforms. The fact that itanic leaves a lot of work to the compiler, and the companies involved then patented that work doesn't help either. But on x86, gcc-3.4 will perform roughly on par with icc.

In fact, numerical kernels like atlas perform very close to cpu peak performance when compiled with either of them. If you want to bash a compiler, try MSVC.

Don't take my word for it, but do some tests yourself. I did

I know Debian has a package of it for MIPS/Linux so it's probably still possible to build it on IRIX. I wouldn't know; I haven't used Pascal in years...

I heard rumours of people porting XFS to FreeBSD.
I've never seen anything released, though. (Unfortunately, since I might seriously consider retiring my Linux server if there were a serious journaling FS for a *BSD).

Since the OS-X kernel is based on the FreeBSD kernel, at least theoretically, it should then be possible to port XFS to OS-X.

But if your aim is to read the disk of an Indy, it's probably still less work to stick the disk in a peecee and boot it from a Knoppix CD. Or stick it back in the Indy, and do something with it!

PS: If any of this has anything to do with removing the (root) password from the Indy's OS, that's a FAQ.

If you're serious about programming, you want to read something like "Design patterns". I'm currently halfway through "Generic programming and the STL" which is the best C++ book I've read for a while.

You could always install MIPSpro 7.3.x as a 'module' in /opt, with it's own IDF and IDL. I did that on my Octane, and never noticed any brokeness. I even had 7.2.1 on it (as a module), pretty sure it was there untill about the time I upgraded to 6.5.23

Wrote on the subject of yet another netboot from linux victim...got halfway at Nov. 6, 2005, 4:37 a.m...

There are two gotchas when using a Linux box as an install server:
1) local port range. You obviously got that covered, or the thing wouldn't boot at all.

2) During the install process, the IRIX miniroot rexec's several shell scripts on the install server. On Linux, /bin/sh is GNU bash which isn't quite the same. Read the faq again about using csh or ksh or recompiling bash with a special flag. Be advised that most Linux distributions don't boot when /bin/sh != bash, which is pretty bad in itself.

I'm currently rebuilding my Linux server and plan to setup a virtual install server using vserver (similar to BSD jails and Solaris zones). This way I can hopefully find a combination that works for IRIX without causing crazy mods to the Linux side and doesn't require wide open BSD r* services on the actual server. If I figure out a recipe I'll turn it into a FAQ.

There is also a rumour that NT ran on a modified Indigo(1), and late Indigo PROM revisions have the BE tag as well. Coincidence? Let the conspiracy theories begin ...

One of the key differences between IrisGL and OpenGL was that OpenGL was platform independant and thus didn't contain the support for window management and fonts that was in the original GL. GLUT was an attempt to recreate (some of?) the missing functionality using X11 and OpenGL. So, it should be possible to create a GLUT over GL; in fact it should not be more than some kind of a wrapper. Then again, it's been awhile that I did serious work with IrisGL.

Someone else had similar problems with other things, and as far as I know there's no solution - you can't compile C++ programs that use GLU with gcc on Irix. If anyone knows otherwise, pipe up!

What about compiling your own from source, with GCC. Make it a static library and you don't have a clash with what's on IRIX already.

You'll not getting working, unless you can buy/built one of theses.

My experience is different.

A few years ago, I hacked together a serial cable for an Indy or Indigo2, and it didn't work properly.
I then disconnected all hardware flow control lines (only TX/RX and GND left, so the most basic serial null modem cable), and it worked.

I use a generic windows PC with HyperTerm to connect. Of course you have to disable hardware flow control before you try to connect.

These days, I have a bunch of cables:
1) DB9 => DB9 nullmodem (for O2 and Octane)
2) DB9 => mini-DIN8 nullmodem (for 4D/35, Indigo, Indy, Indigo2)
3) DB9 => DB9 (male->female, special wiring for 4D series, looks suspiciously like a serial extension cable).
4) A real serial extension (male->female) to reach boxen that are too far away otherwise.
I'm pretty sure none of #1 ... #3 has more than 3 wires inside.

What I should have done was something like this .
But when I need just one more cable, I get just that cable, rather than redoing the entire collection. But still, this is pretty ingenious. One day ....

Hope this helps.

* I didn't get one for the Crimson (it asks for entitlement IDs), even if I register it as an Indy :lol:

So far it looks like what they're saying is correct: if the hostid is in their database, they generate a new license. Lots of my systems are from universities and were previously covered by Varsity. I'll try to get licenses for my Indies, see what happens

I'm sure there must have been a nice spike in the network traffic @ sgi.com yesterday, I refreshed my mirror as well :wink:

This is probably not the best way, but here's how I did it. Various Linuxisms (debian 3.1) may be hidden in here.

Code:

  #!/bin/bash
  
  #set -x
  
  # Freeware (fw) doesn't have books in it's collection
  
  COLLECTIONS="0530 0620 0630 0640 0650 hdwr linux nt"
  
  WGETOPT="-m -nv -T60 -t0 -nH --cut-dirs=2"
  
  for coll in $COLLECTIONS; do
  
  mkdir manuals_$coll
  
  echo "#!/bin/sh" > wget_$coll.sh
  
  chmod 755 wget_$coll.sh
  
  echo "cd  manuals_$coll" >> wget_$coll.sh
  
  lynx -dump -width=999 "http://techpubs.sgi.com/library/tpl/cgi-bin/browse.cgi?db=bks&coll=$coll&pth=ALL" > dump_$coll.txt
  
  # Get part numbers
  
  grep "download.cgi" < dump_$coll.txt | cut -d '=' -f4 | sort > manuals_$coll.txt
  
  MANUALS=`cat manuals_$coll.txt`
  
  for book in $MANUALS; do
  
  major=`echo $book | cut -c5`
  
  echo "wget "$WGETOPT" http://techpubs.sgi.com/library/manuals/"$major"000/"$book"/pdf/"$book".pdf" >> wget_$coll.sh
  
  echo "wget "$WGETOPT" http://techpubs.sgi.com/library/manuals/"$major"000/"$book"/dl/"$book".html.tgz" >> wget_$coll.sh
  
  done
  
  done;

This creates dirs 'manuals_0530' etc. and scripts 'wget_0530.sh' etc.

Scripts look like this:

Code:

  #!/bin/sh
  
  cd  manuals_0530
  
  wget -m -nv -T60 -t0 -nH --cut-dirs=2 http://techpubs.sgi.com/library/manuals/0000/007-0603-100/pdf/007-0603-100.pdf
  
  wget -m -nv -T60 -t0 -nH --cut-dirs=2 http://techpubs.sgi.com/library/manuals/0000/007-0603-100/dl/007-0603-100.html.tgz
  
  ...

After inspecting the "wget_*.sh you run them.

Expect these download volumes (kB)
184928 manuals_0530
247840 manuals_0620
252076 manuals_0630
284396 manuals_0640
562524 manuals_0650
805100 manuals_hdwr
210080 manuals_linux
68356 manuals_nt

This is both the online (html.tgz) and pdf versions.

Yes, and given that BLAS, LAPACK and co. are the defacto standard libraries for this sort of business should tell you something about the real world value of quad precision floating point. In my experience with numerical solvers, everything beyond the 13th decimal was noise, and you can do that easily with double precision.

Yeah, right.

I've got a DM10 (actually, a red adaptec) in my O2. Recently, I got myself a LaCie d2 Extreme 500GB disk with firewire, and for kicks I plugged it into the O2 -- BLAM instant kernel crash. Oops, I guess it wasn't hot-pluggable. Restart with the firewire disk connected, and it seemed to be fine -- until halfway through a 'diskperf' run -- BLAM another kernel crash. OK, I get it, that's enough punishment for me -- disk goes back to server backup duty (what I bought it for in the first place).

Wrote on the subject of pathscale compiler, anybody? at Sept. 5, 2006, 8:16 a.m...

In 2001 SGI released 'open64', which is basically MIPSpro, with the frontends (licensed from EDG) replaced with GNU, and the MIPS code generator replaced with one targeted at the IA64.

'open64' was never a very popular OSS project, probably because of it's complexity, lack of support by SGI, and lack of people with IA64 hardware.

Then some of the key people of the original SGI compiler team created a new company, retargeted open64 from IA64 to x86-64 and voila: the pathscale EKOpath compiler was born. They added all sorts of goodies (openMP etc.), but the source code of the compiler is still covered by the SGI OSS license. If you google for 'open64-alchemy' you can find it. And it builds, not only on an opteron (which I don't have), but even on an ordinary x86! With IPA, LNO and all the other goodies I loved so much in MIPSpro

Right now it's busy rebuilding itself (I bootstrapped it with GCC), if that works I'll throw some numerical codes at it. I'm just wondering why it seems to be relatively unknown. And I wish they hadn't removed the MIPS backend. Just imagine

So, does anybody have any experience with this compiler (on x86 or x86-64)?

My attempt to rebuild it with itself was less than successful, but that was probably due to my own incompetence/inexperience with the thing.

I tried to compare compilation speed between this and GNU g77 by timing both when building the NAG Fortran library (2626 files, ~800K lines), but failed because g77 doesn't compile all of it :roll:

Next attempt is to compare the speed of the code generated by building ATLAS with it, and benching it against a GCC built one. An issue came up where the compiler is too smart for a calibration program.

But I'd seen that one with MIPSpro on IRIX already. Right now it's building. That's going to take a couple of hours, we'll see what comes out.

If I were doing HPC type of things with an AMD64 or EM64T box or cluster I'd definately check them out. http://www.pathscale.com/ekopath.html

Always GCC first, then pathscale. Most of the math kernel is handcoded, so for large cases this is where the computation time goes and both score equal. In small cases, pathscale wins. In fact, it keeps the cpu very close to peak performance for the whole range.

I'd say it's time to update my list a bit. Here's my collection:

Big iron:
* 4D/210 GTX (pinstripe of death :cry:

)
* 4D/420 VGX
* 4D/380 VGX, FDDI, IPI, VideoLab (currently being resurrected)
* Crimson Elan
* SGI 2100, 8x R10000, 8GB RAM
* Onyx2, 1x R10k, IR

Workstations:
* Personal Iris 4D/35 TG
* Indigo R3k Entry
* Indigo R4k XS24-Z
* Indigo R4400 Elan
* Indigo2 R4400 Extreme
* Indigo2 R8000 Extreme, FDDI
* Indigo2 R10000 MaxImpact+TRAM, G160
* Indy R4400 XZ
* Indy R5000 NG1-24bit, FDDI
* 2x Indy R4400 NG1-24bit, to toy with Linux and NetBSD
* O2 R10000, AV, DM10 (red adaptec)
* Octane R12000 SE

There is one old PC acting as a server, and a newer one acting as, ahem, a PC.

There are several more or less complete Indy/Indigo/Indigo2's around still that I have to get rid off of strip for parts. Several boxes full of 4D series boards. I'll probably get rid of the 4D/210 because it takes up too much space and I have better toys now.

Plans for the future:
* Get the Predator back in shape.
* Upgrade as much old (pre 100MBit) hardware to FDDI as possible
* Get an RE boardset for the Crimson
* Upgrade the 4D/420 to a 4D/440
* Get 400MHz cpus for the Origin and move the old ones to the Onyx2
* Continue installing bigger and more quiet harddisks
* Sort out the huge pile of spares/books/cables/cds/tapes etc. I have.

* Build a website for all of this.
* Either convert the garage into an office, or (better) build an extension to the house so I have enough space :lol:

Wrote on the subject of Moving a cat? at Oct. 31, 2006, 10:04 a.m...

Our cat came from Switzerland originally, and was moved to the Netherlands ~ 5 years ago.

We moved this year and for two months lived with my parents who don't like cats so she went back to Switzerland for that time. Recently we took her back to the Netherlands. So she's an experienced traveller by now :wink:

A few observations:
1) Driving at night means the cat freaks out everytime you overtake a truck due to the lights flashing by.
2) When we moved her to Switzerland she spent a few nights in an asylum before we took her to Switzerland, so she was already somewhat stressed. Then we gave her the pill and before it could properly calm her down we took of. She was very stressed because of that, and by the time we arrived the cat had almost no voice left and we were exhausted as well.

I would definately recommend giving the cat a tranquilizer, but I'm not sure giving them two days in a row is a good idea. especially if it's an old cat.

Btw: Netherlands - Switzerland takes about 8 hours.

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 )

major hacking (which would probably look something like: install on an Octane or other 64-bit architecture, move disk to IP27, move over at least /unix, /usr/sysgen and /usr/gfx, attempt boot whilst praying, and most likely move over some more files.

An Octane (IP30) kernel wouldn't contain hardware support for IP28 hardware such as the GIO64 and EISA busses, SCSI, seeq ethernet etc. etc. so wouldn't boot.

A better approach would be to add the arch specific files from .22 to 6.5.30 and rebuild the inst images. With a little luck the kernel API didn't change. Of course the advantage of 6.5.30 over .22 for this old hardware doesn't make the effort worthwhile or someone would have done it already.

* Upgrade MC2 to 256MB RAM.

At that time I may have to upgrade it to IRIX 5.3 also. Not that I want to, but I don't have the drivers for the FDDI and SCSI board for IRIX 4.x. For IRIX 5.3 they're all on the CD, but for IRIX4 they were on seperate discs and of course these are long gone. Even SGI can't seem to find them anymore

In this configuration, with two 5.25" full height harddisks it consumes about 875 Watts electricty, or about 2.35 EUR/day

I tried once, but didn't get very far:

Any memories? I'm assuming the host side is pushing commands into the memory space of the GM so if you know where to set a breakpoint (on the host and/or GM) you might actually see this happening?

Updated. Now has the maximum memory (256MB), 100MBit network (FDDI) and an additional dual channel differential SCSI board (Interphase 'Jaguar').
