Hi,

we are succesfully using Oscar 2.0 + RedHat 7.3 since more than year on a large
cluster with 100 CPUs (I only had to update the kernel in order to have support
for recent 1G network cards). Great work !

During the last year several new releases of OSCAR came out, but it seems to me
that I need to completely reinstall all my nodes if I want to update (this would be
quite a pain since we added several local programms and since we use the local disks 
for
data storgae).

Is there any way to update OSCAR from 2.0 to a newer version ? This would be cery 
usefull
since it is difficult to reinstall a large cluster in order to take advantage of the
improvements and bug-fixes of new OSCAR releases.

If I can not update OSCAR as a whole, is it possible to update individual packages,
in particular Maui and OpenPBS (openpbs-oscar-2.3.16-7 and maui-oscar-3.0.7p8-5 that
came with OSCAR 2.0 have some minor bugs, e.g. wrong detection of main memory on the
nodes) ? By the way, what distinguishes the oscar version of these tools from the
publically available ones ?

Thanks for your help

Holger
