This is probably an ignorant question, but here it is:
I am not that familiar with Cray systems, but my understanding has
always been that they transfer large amounts of data when an I/O
request is made. This seems to contradict my perception of UNIX
using relatively small block sizes spread randomly across the disk.
Does UNIX on a Cray use a modified file system, raw I/O, or some other
method I am not familiar with? If it uses a modified file system,
what does an I/O access look like in terms of block size and
randomness?
If you think the response to this is below most on the net, please
email responses.
Thanks in advance!
