Dear All
Oliver Keeble has just presented a middleware roadmap to the GDB. The key points to note regarding releases are there:
Clients on new ‘platforms’
*************************
SL5 WN 32/64, SL5 UI 32
SL4/SL5 Python 2.5
Debian4/32 WN
SL4/SL5 + changed compiler ???
which one, 3 aren’t an answer gcc4.3?
Imminent or available updates
*****************************
FTS/SL4 (available)þ
Globus bugfixes (available)þ
lcg-CE – further performance improvements
Results of WN working group – cluster publishing
New services
************
• glexec/SCAS
• glexec is being verified for use with experiment frameworks in the PPS (setuid mode, without SCAS)þ
• SCAS still in ‘developer testing’
CREAM
*****
• First release to production imminent
• NOT as a replacement for lcg-CE
• Issues with proxy renewal
WMS/ICE
*******
• Patch under construction
Glue2
*****
• OGF Public Comments are now over
• Glue WG will incorporate these during October
• Will be deployed in parallel as it is non backward compatible
SLC5 WN will be put on lxbatch by the end of September for the experiments to try. We should expect a general release in October.
CREAM will be deployed in parallel at some sites but there are some known issues with putting it into production - for example the current WMS can match to it but not submit to it.
For SL5 in general, there is a discussion about an approach to the build that would no longer allow co-location of services (apart from explicit exceptions). This is to avoid delays where a Globus update impacts one service but not another. The SL5 schedule order would be clients, VOBOX, Storage 32/64, CE ...
There are other things to consider in the middleware area. Please take a look at the slides: http://indico.cern.ch/materialDisplay.py?contribId=1&materialId=slides&confId=20245.
