Thank you for the overwhelming response to the draft. I read all of your
mail with great interest and I will commit many of the changes that you
proposed. Sepcial thanks go to Jeff, Brian, Jared, Serguei, and Joseph.
After I complete the rewrite and the target is clear I will contact some
of the vendors that showed interest. This will take another ten days
because of other urgent matters.
Brief list of changes:
*) The 2 hubs will go; we will get a second switch instead.
*) Channel bonding will be used.
*) A GBit ethernet for switch to master will be considered. This will
need more homework to make sure things will work out as expected. (will
channel bonding mess this thing up?)
*) A tape with autoloader will be selected. All recommentations welcome.
*) A second SCSI card for the tapes will be used.
*) Cooling and noise insulation will be explicitly mentioned in the draft.
*) KT 133A, 133 MHz memory, and the 133 MHz FSB Athlon.
*) NIC types will be explicit, maybe the Intel EEPro100, or 3Com 3C905.
*) Network booting will be reconsidered. The key idea was to simplify
kernel upgrades. There are other ways of doing so and they may be better.
*) The chassis will be explicitly mentioned.
*) The key component prices (memory, CPU) will be checked by talking to
On the software side (which is not needed as part of the proposal but I
guess will take the most time to make right):
*) The PGI-CDK will say: we run a 16-node parrallel HPF code and only
this one compiles it. It will be made clearer. We only need 1 copy of
*) PVFS, LVM, NovaNet 8, MPI/Pro will be considered.
