Why did SGI use VxWorks???

Unread postby Nihilus » Thu Mar 12, 2015 5:09 pm

Nowadays it id a well-known facts for enthusiastic SGI lovers that they used VxWorks (and even x86) for some works in their IRIX(!) development.

Does anyone have a rational description/idea why it was so?
SGI Systems: R4K :Indigo:/256MB/XS-24, R5K 150MHz :Indy:/160MB/XL-24, R10K 175MHz :O2:/640MB, R12K 400MHz :Octane2:/Vpro6/1GB & R4K 250 MHz :Indigo2IMP:/128 MB/XZ Extreme/GIO64 FDDI

As far as I know, the relationship between Irix and vxWorks is that back in the day Irix was supported as a development platform/environment targeting VxWorks/MIPS embedded systems, since the MIPS Pro compilers produced compatible (with VxWorks/MIPS) exe objects.

If SGI used VxWorks internally in any capacity themselves, it was probably for the embedded parts of their HW. Stuff like the system controllers and what not.
