Thanks in advance for the help!
----------------------------------------
My employer just acquired a SunFire server w 16 dual-core Opterons (model 8220, 2.8 GHz) and 128GB of RAM.
Despite the faster clock and memory interface, it's running my Quartus jobs slower than a 2-year old dual-core Opteron (2.4 GHz Model 250).
I suspect my I.T. dept just did a generic configure, and missed out on some major performance tuning opportunities. Maybe they've left a power-saving mode (like PowerNow) in place?
Can anyone suggest the biggest-bang-for-the-buck things to look at?
I don't have root privelege, but I'm trying to help the I.T folks along.
