Doop-de-do, logging in to the new machine.

Huh. I wonder how many processors this machine has.

[stgreen@hogwarts 13:38:22 ~]$ /usr/sbin/psrinfo -v

        and has a sparcv9 floating point processor.

OK. That's a lot of processors there. I wonder how much memory it has.

[stgreen@hogwarts 13:38:27 ~]$ /usr/sbin/prtconf | head -2
System Configuration:  Sun Microsystems  sun4v
Memory size: 261856 Megabytes

Uh, wow. That's a lot of RAM. I wonder how much disk space.

[stgreen@hogwarts 13:43:49 ~]$ df -hl 
Filesystem             size   used  avail capacity  Mounted on
/dev/dsk/c0t0d0s0       15G    10G   4.6G    69%    /
swap                   161G   414M   161G     1%    /tmp
swap                   161G    56K   161G     1%    /var/run
scratch                134G    60G    74G    45%    /scratch

Heh. So I guess at start up we should just cache the disk then, right?

Anyone have any single instance, multi-threaded search scalability tests they want me to try?
