In recent months I have got two SGI IRIS Indigo machines: an older one with the 32bit MIPS R3000 CPU and a newer one a much more powerful MIPS R4000 processor (the firs 64bit CPU which was available for the SGI computers).
The boxes are both pretty snappy. Of course, when it comes to raw CPU power, they may be a bit slow. But for most normal applications they are more than OK (I have the IRIX 5.x on both). But even the R3000 one is not slow (it has a 33 MHz CPU). For example, I spent last night in debugging of my program for the GNU Octave and it wasn’t slow. There is a problem with 3D stuff – my machine has no Z-buffer card so many IrisGL and OpenGL programs or refuse to start at all (the FSN, for example) or they have some problems (the Andy Johnson’s Battalion). But a lot of things works well. Actually, I haven’t have too much time to play with it 3D graphics here. I will do it in a future, I hope.
I also did installed the MeshTV visualization software but at the moment I have no software which is able to output it’s SILO data format.
It is quite hard to use such machine for WWW browsing (the Gopher is OK, though). Available programs even cannot connect to most sites (the HTTPS support is too much outdated here). Fortunately, there still are some sites which are optimised for older browsers. So I installed the Netscape 3.0.1 for IRIX and started to use it.
The interesting thing is that the box is very quiet. It’s two SCSI drives are noisy at all which is quite unusual. It’s much quieter than my main workstation (the SGI O2).
The Indigo with the R4000 CPU arrived last week and only today I have managed to set it up. There are some damages from shipping (they broke the frontal doors) but it works. It is interesting that the CPU is a PC model (no secondary cache) which is known to be too slow in modern systems (the Indy and the Indigo2). But this system is fast (at least it feels fast). This machine came with the “Entry” graphics which is really basic: no (Iris|Open)GL hardware, just 8bit colors with dithering and only the 1024×768 resolution (and nothing better or worse). But it has a normal VGA connector which is nice (the 13W3 connector is here, too). So it’s more a general-purpose workstation for 2D tasks than a workstation for 3D modelling.
Actually, I’m thinking about making it my main machine for non-internet and non-3D tasks as it is possible to run here the most of things that I need (the LaTeX, the XFig, teh GNU Octave, Gnuplot and most of my own program codes). But I will see…
