Molpro2000.1 on Linux

[Jyh-Shyong Ho]

Dear Dr. Moore,

Thanks for your information, I'll try again. My Athlon system uses one
IDE
hard disk,
so if my Molpro runs well ( I hope), I'll list the hardware components
of
my systm.
The first motherboard for dual Athlon CPU was released this month by
Tyan,
you can get more information from their www page: www.tyan.com. The
mothernoard
uses DDR registered ECC memory (you can order it from www.crucial.com)
and
have
a dimension different from most of motherboards, so it requres larger
case
and special
power supply.
Some PC hardware stores in Taiwan are selling the motherboard with the
case

and a power supply. In the near future there will be more motherboards
for
dual
Athlon CPU available, considering the price and performance of the CPU,
it
is very
attractive to have a PC cluster consists of dual Athlon CPUs.
