Hi,
I'm migrating from an i686 to an EM64T machine (Intel core 2 quad) and
I'd like to know whether there are specific options that I can pass to
gcc for an optimization of my code or if everything is blindly set up.
How would I manage the 4 cpu cores if I was to write in assembly?
GCC has a
Many thanks, I'll read your link with attention. Do you have further
links on threads and IPC ?
I'm thinking in rewriting an old and unfinished logical interpreter in C
that used assembly code (nasm) for truth evaluation of the smallest
elements. I'd like also to create a small database for prime

You almost certainly wouldn't. Very few people have any reason to write
in assembly anymore. You might write a critical section of code in
assembly, but all the glue ought to be in C, inluding anything to manage
pthreads to do
The loop sharing looks exciting but openmp seems difficult to use too.
Does openmp replace pthreads or work in combination ?

AFAIK it use pthread to work but it create all necessary pthread at startup to
avoid creating them at each loop
There is an environment variable GOMP_AFFINITY in libgomp that binds
threads to single cpus. Can I use it the same way with multi-cores (i.e
GOMP_CPU_AFFINITY=0 1 2 3 in order to bind thread 1 to core 0 etc..)?
Is this a good way to take advantage of the quad architecture?

I thought IA-32e was something entirely different (I
thought that was PAE and such).
No, its the term used for the EM64T extensions in most of their technical
documentation (e.g., the SDM for IA-32 processors). Why, I don't know. They
just like to be difficult.

So intel went from IA-32e to EM64T to Intel 64! I guess you know why upstream
left it amd64. I guess they suffer from the not

What about em64t?
Thanks.

I'm not sure why you're asking this? Is it because it's an

Yes.
Do you think it's going to behave differently
