First, we got this Alpha station which for all the world runs like an
AS 500/500, but it's made up of a PC164 motherboard with a 500 MHz CPU,
and some custom selected peripherals. This is one screaming fast
processor! Our signal processing applications have never run faster (in
a single CPU system).
In the User's Manual for the AlphaPC164 Motherboard, the section on
memory upgrades says that with both banks populated (and the jumper
properly set), the memory bus becomes 256 bits wide instead of 128 with
just one bank populated. My question is: If I did this, would I see a
significant improvement in performance going from 128 bit to 256 bit
memory bus? If so, I would spring for the memory in the second bank.
Second question: One of our users got some code off the net (i'm not
sure of its function yet) which we're having a really hard time
compiling. It seems that one of the include files defines a static
character array initialized with some 67000+ characters(!). Putting
aside my feelings about psychotic programmers who write pathological
code like this, is there some flag in the cc or cxx compilers that we
can use to make them accept this long line? (Even vi breaks up this
line into 47 pieces.) We have been unable to get DUNIX to compile it,
but were able to compile this on an old SGI system, and rumors has it
that it compiles on an IBM system, so there is no real syntax problem
with it.
thanks in advance for any answers.
