Does Xilinx ISE benefit from Multi CPU setups? Like offered by AMD Athlon64 X2, AMD Opteron, Intel Core2Duo etc..?
Also would AMD AM2 socket + 800MHz DDR2 be really benefitial compared to non DDR2 motherboards?
Xilinx ISE + Multi CPU setup?

A multi-core or multi-CPU setup isn't going to run ISE faster (AFAIK), but your computer will still be a lot more responsive while running CPU intensive tasks. However ISE will run faster with CPUs featuring 4 MB L2 cache, such as th mid/high-end Intel Core2 Duo CPUs (if I…

Curious on the linux version of ise.
A multi-core or multi-CPU setup isn't going to run ISE faster (AFAIK), but your computer will still be a lot more responsive while running CPU intensive tasks.
However ISE will run faster with CPUs featuring 4 MB L2 cache, such as th mid/high-end Intel Core2 Duo CPUs (if I recall correctly models E6320, E6420, E6600 and higher).
To give you a single data point, my MAP/PAR time reduced by about
20% when i went from a 2MB Core2Duo (E6400?) to 4MB (E6600) at the same clock speed (2.4GHz).BTW, going to the 2MB Core2Duo from my previous 3GHz P4 halved the time!

Unfortunly the Intel Core2Duo seems to have both security & integrity problems:

When loading data from L1 cache it will occasionally have stale data.
Any tip on a AMD cpu that will perform?
It looks like it could occasionally get it's cache wrong. Very occasionally - "not been seen in commercial systems".
Not that is guaranteed errata-free :-)
Just get
1) a big cache 2) Low latency main memory... 3) ... and lots of itCheers, Martin
