Spacely is up and running. Spacely is now an E6500 with 14 400MHz/8MB CPU's 
and 16GB of RAM, running Aurora Tangerine 1.92.  Some information:

If anybody has EX500 CPU's, 400MHz/8MB cache, that they'd like to donate, I 
have a few more of the 501-4882 boards that can take that CPU and have 8 more 
slots to fill (16 CPU's more, 30 total) (one donor has come forward with some 
boards and such, and I am very grateful for that!).  

Otherwise, the other 501-4882 boards will go into the E5500 that I robbed the 
400/8MB CPU cards from, and they will get 400MHz/4MB cache CPU's.  Not sure 
how much RAM I have left to fill the slots, though.  I think I can get 12 
CPU's in the E5500 (if I get another or two 501-4882 boards, I'll max the 
E5500 out with 14 CPUs).  The E6000 will get as many 336MHz modules as I can 
scrounge from the 3500's (which are giving up their CPU/memory cards to the 
E5500) and put on the older CPU/memory cards. The smaller DIMMs will likely 
go in the E6000, and it probably won't be powered up often.  I have a pretty 
good case for leaving the E6500 on (looking at running my e-mail server on 
it) and might have a case for the E5500 (as long as I can keep power 
consumption down).

On benchmarks, I've run a Unixbench 4.1 run on the E6500 (see the Aurora-devel 
list for the details) against another Unixbench run on a Dell PE2650 Dual 
3GHz Xeon server.  The results are telling in the high concurrency vein; the 
16 concurrent shell script run on the E6500 pulls 244 lines per minute (lpm), 
on the 2650 I see 366 lpm.  The other benchmarks on the suite are single CPU, 
but even then the 2650's Xeon is only about 5 times faster than the 
400MHz/8MB cache UltraSPARC. 

Now, as to plans for a buildsystem.  I am willing to provide ssh access to a 
user account, RSA/DSA key only, to one or more CentOS developers (I have 
extended much the same offer to the Aurora folks).  I figure that 16GB of RAM 
might be large enough to do the buildroot in ramdisk; correct me if I'm 
wrong.  Doing the build totally in ramdisk might make builds go more quickly.  
Pasi, let me know.  The Aurora folks would prefer development efforts to 
concentrate on Aurora, with an eye to putting the results into CentOS.  The 
Aurora folks are working towards using plague and mock as their buildsystem; 
google for them to find the info (don't have links handy).
