Using Multiple Processors for TCP/IP and/or SFS

2009-08-20 Thread Michael Coffin 
Hi Folks,
 
Following up on our earlier discussion of multiple virtual CPU's for
Linux, will TCP/IP and/or SFS servers use multiple processors?
 
Here's my situation, I have 1 general purpose CP (about 421 MIPS) and 2
IFLs (about 500 MIPS each).  We have excess capacity on the IFL side of
the house (ear-marked for future Linux use), and would love to use some
of those MIPS for TCP/IP and/or some of our SFS servers, both of whom
can be a bit piggy at times.
 
If I define one CP as BASE and 1 IFL as CPU 01, will TCP/IP and/or SFS
use both processors?  I can then manage their relative use with SET
SHARE.

Mike,

TCP/IP can be configured to dispatch device driver work on non-base CPUs
by coding the CPU num option on the DEVICE statement in PROFILE TCPIP.
Other than that it won't do anything with multiple processors.

TCPIP can, see page 633 of the 5.4 TCPIP Planning and Cust guide.
SFS, no.
