Hi, As usual, I'm not at all sure that I can make this meeting (it overlaps with one of the physics meetings I regularly attend). But, I thought I'd add my two cents worth. SLAC may already have a great deal of experience at this -- but we found that testing modern dual-head 4 core (i.e. total 8 core) machines took longer than normal. We had to tweak some Linux OS parameters in order to really get the machine to run properly. A caveat in this is that we are using this as a DAQ machine and so we use shared memory to move data round, and most of what we did had to do with that. But, none-the-less, I would allow for a longer-than-expected testing time if SLAC hasn't already had some experience with these 8 core CPUs. I don't know about you guys -- but it is seems to me that at the rate we are adding cores to pizza boxes our usage model is going to break down (i.e. one core, one job). It seems at the straining point right now. Cheers, Gordon. > -----Original Message----- > From: [log in to unmask] [mailto:owner- > [log in to unmask]] On Behalf Of Stephen J.
