Quick question then: You have /mnt/pvfs2/* as your pvfs2 filesystem, is this a mounted filesystem through the vfs? or is this the location of the filesystem without the pvfs2-client-core/vfs layer?
In my observations with ib, I've noticed in that the vfs performance can be quite lacking. can you try unmounting the vfs and rerunning the test to make sure you're using libpvfs2 and not the vfs? ~Kyle On 10/11/07, hyeyoung cho <[EMAIL PROTECTED]> wrote: > > Hi. > > We didn't install ib-srp. > To make it clear, we also excluded 'ib-ipoib' and only installed 'ib-verbs', > 'opensm', and 'ibadm'. > > [EMAIL PROTECTED] tmp]# /usr/local/bin/pvfs2-cp /tmp/test1G2 > /mnt/pvfs2/test1GB01 > -t > Wrote 1073741824 bytes in 23.000803 seconds. 44.520185 MB/seconds > > Thanks, > Hyeyoung Cho > > -----Original Message----- > From: Kyle Schochenmaier [mailto:[EMAIL PROTECTED] > Sent: Thursday, October 11, 2007 1:05 AM > To: Kevin Harms > Cc: hyeyoung cho; [email protected] > Subject: Re: [Pvfs2-users] pvfs performance over IB > > Are these tests all done in memory, or are you actually hitting disk here? > 60MB/s on a system that can do 100MB/s isnt *terrible* if you're > hitting disks, however, if this is all still in memory, thats a > different story. > > Can you redo the pvfs2-cp test with a 256MB or so test from /tmp? > > ~Kyle > > On 10/10/07, Kevin Harms <[EMAIL PROTECTED]> wrote: > > > > are you using SRP? > > > > kevin harms > > > > > > > > When I tested using iozone, the results was read 145MB and write > > > 100MB(MAX). > > > > _______________________________________________ > > Pvfs2-users mailing list > > [email protected] > > http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users > > > > > -- > Kyle Schochenmaier > > -- Kyle Schochenmaier _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
