Tru64 Managers,
This question is more about Alpha CPU performance than Tru64 UNIX.
If there is a more appropriate venue for this question, please redirect me.
We are shopping for floating-point performance. Our top candidate is a
cluster of Intel/AMD machines running an open-source Unix. However,
because the faculty's research may be far from trivially parallelizeable,
we are also considering a few fast, single-processor Alpha workstations.
A Compaq salesperson recommended a DS20 with an 833 MHz CPU. For the price
of one DS20 with 1 GB of RAM, we can buy seven cluster nodes, each with two
1.2 GHz Athlon processors and 1 GB of RAM. Our dilemma is this: is the
Alpha worth the price? Does anyone have some real-world floating-point
performance statistics of this machine? We already have a few XP1000's;
if someone could relate the performance of these two Alphas, we would be
very grateful. Of course, we realize that the only results that would be
truly meaningful to us would be those from our own code. C'est la vie.
Thank you in advance.
-Eric
