yes - but note that you get "floating point assist faults" when for example
your application code has the odd underflow.  A side-effect is that messages
get written to the console and even /var/log/messages (caused just by normal
round-off in a scientific application!).

The result is the code goes slowly - in one case of ours the code run 13
times slower than it should.  If you set the flush-to-zero flag in the FPU,
it runs at full speed again. You can do this either by an assember call or
options like -ftz to the intel itanium compilers.




Yours,
Daniel.

Subject: kernel 2.4.9-34 ia64 bugfix list?


hello-

i'm currently running Linux 2.4.9-31smp on my redhat7.1 ia64 box.  i was
looking into upgrading to redhat's 2.4.9-34 kernel, but i cannot seem to
find a list of ia64 bugs that are fixed by it.  does anyone know of such
a list?  i'm currently having random oopses and mapped out banks of
memory with this machine so i dont want to stray from a supported redhat
configuration.

also, i get lots of error messages about floating point assist faults.
for example:

fdtd(21172): floating-point assist fault at ip 40000000000686e1

what are the ramifications of this "fault"?

thanks for any pointers,

rob.
