Re: Triax profiling on cluster
Yes, all nodes have this but some of them have bigger cache (reason for
the option "big cache") so you don't use RAM at all if possible (but
yeah, if its 6MB then it is useless for DEM...).
All nodes ARE using internal memory attached to a node. You are
confusing something here. Each node is an *ordinary* PC. They are
just connected to each other with a mechanism which allows submitting
jobs (sun grid engine). There is nothing special about them.
Maybe Remi was talking about big CPU cache which is always used
automatically. And indeed is relatively big: a whole 6 MB ! Which
confirms what I already said, if you don't use RAM then Intels are
much faster than AMD (this is the case when you are calculating
digits of pi or mandelbrot set, or such). If you do use RAM, then
AMDs are faster. In our calculations we use RAM. A smallest
simulation uses 100MB. Another simulation could be 1 GB. There is no
point with 6 MB of CPU cache then.
Hehe don't worry, we are learning each day and hardware is changing each
day as well.
Also remember that FEM and most numerical tools need BIG RAM, that is
probably the reason of the 32GB.
Who at the university decided to buy Intels with 32 GB... I don't get it.
man, why I am so upset, better forget this.
