Pete -
I've been working with the 1.4.0 release and got everything up and
running, running tests, etc.
Currently I have only one bug which pops up randomly and causes the
server to kill itself unexpectedly, but I'll hopefully find that soon....
So far I've managed to see a max rate of about 180MB/s from pvfs2-cp.
I havent really seen any single-client data for the vapi-Infiniband stuff.
How are these results looking?
- Does anyone have a link to, or data for tests similar to mine over
the VAPI IB stack? (single-client && single-server)
My setup:
1 meta/data server, 1 'client' which I'm running the tests from,
note: not using the pvfs2-client stuff, just pvfs2-* tests.
1x (meta + data) server on opteron2. pvfs2-fs mounted to ram (/tmp)
client tests run from ram (/tmp) on opteron1.
(all tests here, obviously using the gen2 openIB stack)
64K = 23MB/s
128K = 59MB/s
256K = 86MB/s
512K = 98.5MB/s
1M = 115MB/s
2M = 125.5MB/s
4M = ( <100MB/s for some reason???)
8M = 140MB/s
16M = 142MB/s
32M = 154MB/s
64M = 178MB/s
128M = 166MB/s
256M = 161MB/s
(depending on the test 128MB+ will get ~170MB/s on average)
I'm not exactly sure where I'm standing in comparison to the VAPI
version, nor how this scales yet. Although I'm working on getting a
multi-client system setup here hopefully by the end of the week..(
waiting for a new switch to arrive )
I see some results/graphs from the SC'05 PVFS2 BOF documents, but am
unsure exactly how everything was setup, and/or how all the clients were
synchronized to get an accurate test. Any advice would be helpful as
well :)
thanks,
- Kyle
