Hi Atro -
I have actually never indicated support for Sun SPARC in pmemd; this is not
a matter of disliking Sun at all; it is a matter of 1) not having access,
and 2) not having indications that this is a scorching chip I should be
paying attention to. I am still a bit agog on the namelength thing. In
general, I would probably prefer to not have to live with such an onerous
restriction, but I understand it is annoying for you. So if it is just this
one name, you can of course easily hack up the code to get it to compile. I
would consider issuiing a patch, but suspect the problem will recur as
development continues. Anyway, if you give me the complete list of
troublesome names, I'll at least change those names in the source going
forward, and if I hear more complaints, consider issuing a patch. I think
the deal with the MIPS architecture is that it is just so slow as to be
pretty much useless now - basically not worth the power it takes to run
them. I would think some Origin's might still be running out there, though,
as it was a pretty nice smp. Are we dealing with a couple of workstations
at U of Helsinki, or do you all still have some serious MIPS iron you are
running? Anyone else out there still heavily using a big MIPS SMP?
Best Regards - Bob Duke
