Yes, but you might want to limit a single client to a process and
limit the thread count, for isolation and simple load balancing.
But I am not sure what the use scenario is...
Even embedded parts have many cores; look at every mobile
processor.
Usually limited. Correctness is more difficult to prove with high
levels of parallelism... And you can use FPGA...
Multi-core focused software tends to perform better on
single-core
setups than software that was written for single-core in my
experience.
That is odd. Parallell algorithms usually comes with overhead.
At the time,
we
worried about how the super-scalar choices we were making would
affect
Gamecube which still had just one core.
You meant parallell? (super scalar just means that a single core
has multiple execution units, a single core can schedule multiple
instructions at the same time)
If you write a
single-threaded app, you are almost 100% guaranteed to blatantly
disregard software engineering in favour of a laser focus on
your API
and user experience, and you will write bad software as a
result.
Well, if you need more than a single thread to update a gui (sans
rendering) then you've picked the wrong layout strategy in my
opinion.
I dont want the gui to suck up a lot of cpu time and polute the
caches.
And yes I think layout engine API as well as styling are very
important to do well, even if it incurs overhead.
I'd rather have simple layout if that is the bottle neck...
Layout engine design a styling engine design is really the
biggest challenge. You cannot design the architecture before
those two are known. Also embedded have fixed screen
dimensions... No need for real time resizing...
What is missing is a good detailed description of primary use
scenarios. Without that no rational design decisions can be made.
That is software engineering 101.
Without that we will just talk past eachother making different
assumptions.
What is certain is that the long page browser layout engine isn't
very well suited for fixed dimensions...
