Unfortunately, "cheap" Alphas are limited to either 2Gbytes (UP2000+) or
(DS20, DP264?) of physical memory - which makes the advantage of the large
virtual address space more or less moot. AFAIK, the cheapest Alpha, capable
addressing more than 4Gbytes of physical RAM (ES40), costs about the same as
a cluster of 10 dual Athlon nodes, with 4Gbytes of memory -each-, and a nice
interconnect. Unless you absolutely must have that large address space, an
is not a very good buy  these days ...
