Can I experiement with threads on both software (user) level and kernel (real processor supported threads) level. What about SMT, Super threading and multithreading?
Can I experiement with threads on both software (user) level and kernel (real processor supported threads) level. What about SMT, Super threading and hyperthreading?

For the time being, none of the above, as there is no ported user thread library (AFAIK), and Minix doesn't support kernel level threads (mainly due to no VM).

Minix 3 doesn't take advantage of any advanced features you can't find in a good 486 box.

To clarify before I get flamed *puts on asbestos armor*, That is not anything against Minix 3, it's just a factual comment that Minix 3 utilizes no additional hardware than that which can be found in a decent 486 system. PCI-based 486 motherboard were made, and since PCI is Minix 3's most advanced feature (so far), my statement is correct.
SMPing 486 boards are beyond "decent" to just "Mr. Moneybags", and were a rarity. Or to clarify, you'd have to do better than just "decent" to get a 2 processor 486 motherboard.

Can you explain how you can make this claim? Did you read all of the Minix source code to verify that no advanced features are used?
Your claim is in fact not true. I leave it to the interested reader to figure out which 'advanced' feature is used.

No no it's simpler than that (but good guess) - it's the name of an instruction used to get the value of the cycle counter, that is only available on pentium and up. In Minix it's used to gather entropy for the random number generator. I rot13ed it in order to not spoil things for the 'interested reader'.. :)

Ahh... I am actually half-right on this one, cause you can get a Pentium Overdrive (which was basically a Pentium core with a 486 MMU or someshit like that) and put it in a 486 mobo...
But, like I said, *half* right.
Good one there, pulling up a obsceure feature, I like doing that to people at times...
