help me to understand what is arch-specific

going to leave, have a nice day, hope to see you again soon!

There is nothing arch specific about generic IRIX MIPS-binaries , but it is possible that some binaries depend on specific hardware components, like an EISA bus on the R10K Indigo2 (IP28) or VPro graphics on the Octane (IP30) or the VICE multimedia chip in the O2 (IP32).

Something does the difference as I got a strange errors moving things (1) from IP32 to IP28.

(1) things proved to be working on IP32 do not work not on IP28, this, even if I did a copy preserving file's properties.
(
machine1 : tar -cf app.tar patch, scp app.tar machine2_IP:
machine2 : tar -xf app.tar
)

sorry, I do not have these machines on hand now, I am almost 250Km far from them now
so reporting (again) all the error-messages I got will take time (and I am not sure if I am allowed to post them here)

going to leave, have a nice day, hope to see you again soon!

IP28 supports a 64-bit kernel, IP32 does not.

Graphics hardware can make a difference, for example Adobe Premier on IP 30 works fine with SI, SSI and MXI but with VPRO it hangs permanently at launch, before even putting up it's splash screen.

yes, it happened to a friend of mine because he inserted the hard drive in the wrong octane machine. He owns two machine, one is equipped with VPRO, the other with MGRAS, he wanted to clean both of them, so he removed the hard drives, and a long "oppppsssss" followed when he switched on

I wonder about things made by Alias Wavefront, e.g. StudioSurface.

going to leave, have a nice day, hope to see you again soon!

Alias/Wavefront used to have extensive hardware qualification lists for what their binaries required, they assiduously wanted to avoid people buying their admittedly super expensive software only to find it wouldn't run on their hardware... :roll:

What i forgot to say is that there can also be some implicit target platform optimization performed by MIPSPro compilers. Like:

Code: Select all


   -Ofast [ = ipxx]
   

   Selects optimizations that maximize performance for the
   

   given SGI target platform, ipxx.  These optimizations may
   

   differ between releases of the compiler and among the
   

   supported platforms.  They enable the full instruction set
   

   of the target platform (for example, -mips4 for an
   

   R10000).  Although the optimizations are generally safe,
   

   they may affect floating point accuracy due to
   

   rearrangement of computations (for examples, see the
   

   -OPT:roundoff=3 and -OPT:div_split options in the opt(5)
   

   man page).  Typical optimizations include -O3, -IPA,
   

   -TARG:platform=ipxx, -n32, and
   

   -OPT:Olimit=0:roundoff=3:div_split=ON:alias=typed.  See
   

   the -TARG:platform=ipxx option for information about the
   

   optional argument.

i haven't come across incompatibilities between machines using these specific options, as the man page states.

But even if the CPU is the same between platforms, there are differences in properties like cache misses: on the Indigo2 and O2 an R10000 support only one cache miss, but the Octane and Origin support up to 4 (Info from Ian's site).

You won't preserve all file properties if you don't use the `p' option when extracting,
