We recently ran some tests that we thought would be interesting to
share. We used the following setup:
- single client
- 16 servers
- gigabit ethernet
- read/write tests, with 40 GB files
- using reads and writes of 100 MB each in size
- varying number of processes running concurrently on the
These are great results Phil. Its nice to have you guys doing this
testing. Did you get a chance to run any of your tests with the
threaded version of pvfs2-client? I added -threaded option, which
runs pvfs2-client-core-threaded instead of pvfs2-client-core. For
the case where you're
Hi Phil,
Thanks for running these tests.
I think this buffer size will be dependant on the machine configuration right?
If we work out a simple formula for the buffer size based on say
memory b/w (and/or latency), network b/w (and/or latency), we could
plug that in as a sane default (bandwidth .
Hi Phil,
Attached patch fixes the read buffer bug that you had mentioned and
also implements the variable sized buffer counts and lengths that we
can pass as command line options to pvfs2-client-core.
I did not implement module time options for buffer size settings since
that is fairly
