[daip] optimizing AIPS

Eric,

One question I wanted to ask you -- How would you optimize AIPS for low 
frequency data reduction?

I have two IDE and two SCI drives:

/dev/sda1              34G   28G  5.4G  84% /local/data/lark
/dev/sdb1              34G   33G  290M 100% /local/data/lark2
/dev/hdb1             184G   15G  169G   8% /local/data/lark3
/dev/hdd1             184G   66G  119G  36% /local/data/lark4

So what I've done at the moment is install AIPS on /local/data/lark, and 
put the main two disk areas on /local/data/lark and /local/data/lark2 so 
that I'm reading and writing to scuzzy drives. Is it bad to have the AIPS 
binaries on the same drive that I'm reading or writing to? Then projects 
I'm not actively working on are the (larger) IDE drives.
