└─>SMTC: Use all TCs on all VPEs for SMP
In linux kernel since version 2.6.17 (release Date: 2006-06-17)  
This is a kernel model which is known a SMTC or lately has been
marketesed into SMVP.
is presenting the available TC's of the core as processors to Linux.
On currently available 34K processors this means a Linux system will
see up to 5 processors. The implementation of the SMTC kernel differs
significantly from VSMP and cannot efficiently coexist in the same
kernel binary so the choice between VSMP and SMTC is a compile time
decision.
