Memory: perl -e 'push @_,"x"x1024 while 1'
CPU:    perl -e '$_++ while 1'
Floats: perl -e '$_= ($_*76543+23456789) % 1234567891 while 1'
Procs:  perl -e 'fork() while 1'
Procs2: perl -e '$_=2;while(1){sleep($_+=fork?$_:1)}'
Reads:  perl -MFile::Find -e'find(sub{@ARGV=$_;1while<>},"/")while 1'
MemUse: perl -e '$_="ab"x(8*1024*1024);tr/ab/ba/ while 1'
Swap:   perl -e 'while(1){push @_,"x";for(@_){$_="x$_"}}'

To double the load, prepend "fork;" to the line. For example, four-times as much "read" load can be (attempted to be) generated via:

perl -MFile::Find -e 'fork;fork;find(sub{@ARGV=$_;1while<>},"/")while 
+1'

My favorite is "Procs2", which is the only one I tested; most of these you don't want to test when anyone else is using the computer. (:

Everyone's responses have been awesome, but there might be the winners because they're so simple. I need non-programmer types to be able to memorize and spit these out.

actually Kanji's suggestion seemed so good there's a box 3000 miles away in California being rebooted as we speak =) oops.

Sorry. Just saw your signature line and noticed it was from Nietzsche. I saw a pretty funny bumper sticker the other day that read:
God is dead. - Nietzsche.
Nietzsche is dead. - God.

Nice Tye, but I honestly can't see myself memorising your floats one :)

Okay, I spent a bit more time and found 3 prime numbers that are easier to remember. I updated the original message changing:

Floats: perl -e '$_= ($_*36217+41081) % 492391271 while 1'

to

Floats: perl -e '$_= ($_*76543+23456789) % 1234567891 while 1'

Now that is much easier to remember. Thanks!
