FWIW, I had to convert over to using svn://-style URLs (vs. file://-
style) because my mirrored SVN roots are on an NFS filesystem;
executing a bunch of checkouts simultaneously from the same root is
Bad (and causes some checkouts to fail).
Instead, I setup an svnserve on my cluster head node to serve the SVN
repos in a read-only manner out to my cluster. It was trivial to
setup the svnserve, and it seems to work quite well in my MTT setup.

FYI: per my post to the OMPI devel list, I discovered the
"svnsync" command yesterday. svnsync allows you to
mirror an entire SVN repository in a read-only fashion; I
mirrored the ompi-tests repository locally at Cisco. A
one-line cron job keeps my ompi-tests SVN repo mirror up
to date every night.
Can you post that crontab?
It's just
0 19 * * * . $HOME/.bashrc ; svnsync sync
file:///home/mpiteam/mirrors-svnroots/ompi-test
(repeated for the other SVN repo's I'm mirroring)
See the SVN book docs for svnsync -- they discuss how to setup a
local
repo for mirroring with svnsync (there's a few steps you have to do
to
set it up).
Hence, my SVN checkouts are no longer serialized -- which
had been causing significant delays when the "test get"
phases of many MTT jobs were running at more-or-less the
same time.
If I see this:
$ ls /foo
README.txt conf dav db format hooks locks
How do I "svn checkout" from /foo using a "file:" URL?
svn co file:///foo
A file:// URL is just like an http[s]:// URL -- just put the absolute
directory name after it (to include the leading "/" -- so a file URL
will have 3 /'s).
Ah. The *3* /'s are important. 2 slashes didn't do it :-)
