Network Tests

I have introduced some network tests. Test jobs are sent to every UK site once an hour which attempt to copy a number of differently sized test files (1MB, 5MB, 10MB, 50MB and 100MB) from the Storage Element at each of the sites. The transfer times are then used to calculate the average throughput in MB/s. The results are averaged over the last 24 hours to produce a matrix of site to site transfer throughputs. There is an average over the whole matrix on the main UK Grid page. See http://pprc.qmul.ac.uk/~lloyd/gridpp/nettest.html.

New test

I have enabled a new test which sends an ATLAS analysis job to ".ac.uk" every 10 minutes and wherever it ends up reads data from the local SE and does some analysis. This should give a much better estimate of success rate as seen by users (as jobs won't go to sites that are down). There is still the problem for users whose data is on the site that is down of course). See http://pprc.qmul.ac.uk/~lloyd/gridpp/uktest.html for a summary.

New views

There are a new set of results pages showing all the results for a particular site or Tier-2 on one page. Go to the main page
http://pprc.qmul.ac.uk/~lloyd/gridpp/ukgrid.html and click on one of the institute names down the left hand side. Or click on a Tier-2 just above the big table.

FCR History

I have been collecting the FCR history since just before Christmas. I have now put up a new page that shows the percentage of time each site is blacklisted by each VO using the FCR. This can be found at http://pprc.qmul.ac.uk/~lloyd/gridpp/fcrtest.html and is linked from the other test pages as "FCR".

Late Spring Clean

I've done some tidying up so that the ATLAS tests are more resilient to changing versions of the ATLAS code and this seems to mean that sites with only Release 13 and not 14 are passing again. I have also tried to make all the times consistent - some were previously GMT and some BST. They are now all supposed to be BST in Summer and GMT in Winter.

Release 14 Complete

All three ATLAS tests are now running on ATLAS Release 14. If you want to pass you need to install 14.1.0 or higher.

Release 14 User Analysis Success

Release 14 User Analysis seems to work at some sites at least. The Z mass has gone up from 96.661 to 97.203!
