partitioning HD for use of swap & for booting

[Kent Heyward]

1.    What is the correct partitioning of the hard drive? Currently, I
am booting from the floppy and am not able to use a swap file.
 
2.    Does having a swap file contribute to performance?
 
3.    When I run linpack, I see in the beostatus monitor, the cpu usage
go to 100% and the memory utilization on my 256k node move from 24% to
32%(59m to 80m)and never get any higher.  On another node with 128m, it
will utilize 58 to 90 m.  It appears that adding more memory does not
improve performance on the benchmark.
 
4.    Another cluster uses scalapack as one of their benchmarking tools.
How does it compare with linpack?
