Can someone give me a Sage command to type that can exploit multiple processors,
which I can then time? (I'm not a Sage user really, just helping port it to
Solaris, so don't rely on me knowing python).
Ideally a floating point and an integer example would be good.
I'm somewhat disappointed with the performance of 't2'. In a simple single
threaded task to compute primepi(n) using a dumb algorithm, my PC is was about
20x faster. When the same code was converted to a parallel form, my PC and 't2'
were about the same speed.
I'd just be interested to find something which works quicker on
http://t2nb.math.washington.edu:8000/
than it can on
http://www.sagenb.org/
If it is possible to find something faster run faster on
http://t2nb.math.washington.edu:8000/
than an example would have to exploit multiple processors well. Otherwise, it
will be pretty slow.
't2' is not really designed for the sort of task we are using it for. If it had
a couple of hundred simultaneous users, then it would no doubt work reasonably
well, having 128 threads.
