<Cache conflict is a nonissue in clusters since since each element (can be a multiprocessor element) has its own memory space, but memory sharing (e.g. message passing via gigabit ethernet) latency is.> Well put, perhaps I should have said node, where all processors share the same memory subsystem. The numbers I have seen show saturation does not occur untill 6-8 processors with 2 meg of L2. As you may know, the split transaction based bus architecture is very well suited to SMP and assists in bus utilization. <So if you were to design a system you could sell for the most money and spend the least to build (maximize gross margin), what would you build?> I would add a third condition, that is also to sell the most of, thus maximizing total profit. I am not a systems designer so I am not an expert, but all indications are that those who are experts are designing Slot2 based 4-16(?) way SMP systems (and clusters thereof) based on Intels Xeon and their 450NX chipset. That's the high end for IA. Next would be a 2 processor 440GX Slot2 based systems. The 440GX includes a single 66mhz PCI slot so that helps too. Finally, 2 way 440BX based Slot1. Regarding price, yes it seems outrageous but compared to Sun and Alpha, systems vendors can buy $4500 Xeon 2meg L2 processors and still field a very competative server. That's what's setting the high price, the competition. EP
