NorduGrid ARC 15.03 has received an update to:
Fedora has decided to move to OpenSSL 1.1.0 from next release (Fedora 25). To be a able to continue supporting the newest Fedora, ARC will need to implement support for OpenSSL 1.1.0 from next major release, scheduled for beginning of next year. As significant code changes are needed, some of which are not compatible with earlier OpenSSL versions, we will have to drop support for platforms depending on OpenSSL versions lower than 1.0.0.
The consequence is that from ARC 6.0 only EL6+, Fedora12+, Debian 7+, Ubuntu 11.10+ will be supported.
In particular notice that we will not continue support for EL5 and Ubuntu 10.04 LTS.

If you are running an ARC CE with either WS-interface or the GridFTP interface, or an ACIX service, we advise to update the openssl libraries and renew the host certificates. ARC itself needs no updates.

This year's Nobel Prize in Physics is the first to which ARC has proudly contributed. The theoretical work of Professors Englert and Higgs was supported by experimental data from ATLAS and CMS experiments at LHC, and ARC played a notable role in processing and analysing these data, as well as producing simulated data. Above 5% of all ATLAS and 9% of all CMS computing power has been provided via ARC, and these numbers are growing, as large HPC sites turn to ARC in order to provide computational support to LHC. Let's hope that this Nobel Prize is not the last that ARC will enable!

NB: as a next step towards the new stable release 0.6, all the ARC-related packages starting from December 18 nightly build have prefix nordugrid-arc- instead of nordugrid-. An immedate implication is that the standalone tarball will unpack by default into nordugrid-arc-standalone, thus the users that have the standalone setup done automatically via login scripts, should either change the directory name to nordugrid-standalone, or modify the login scripts, if they wish to use tags 0.5.38+.

An important step in the ATLAS Data Challenges is accomplished on the NorduGrid. The total of 850 jobs processed ca 300 000 events of proton-proton collisions in various conditions. Processing was completed in 11 days, and due to the high memory consumption, the jobs were scheduled by the Grid mostly to the production clusters of the Nordic supercomputer centers. The Parallab Linux Cluster carried out most of the task, with the HPC2N Super-cluster and the Monolith cluster of NSC contributing significantly as well.

Uppsala NorduGrid cluster up and running.
The Lund grid cluster has been upgraded to 6 Intel Pentium 1GHz processors.
Successfull test of Replica and Gsiftp in Uppsala.
The link between Uppsala and Copenhagen is established and tested in both directions.
From Uppsala to Copenhagen:
[ellert@ellert ~]$ globusrun -a -r lscf.nbi.dk GRAM Authentication test successful [ellert@ellert ~]$ globus-job-run lscf.nbi.dk/jobmanager /bin/echo "Hello World" Hello World
From Copenhagen to Uppsala:
lscf:~> globusrun -a -r ellert.tsl.uu.se GRAM Authentication test successful lscf:~> globus-job-run ellert.tsl.uu.se/jobmanager /bin/echo "Hello World" Hello World
The firewall only allows connections from lscf.nbi.dk
The software repository is set up (protected access).
NorduGrid mailing lists for general announcements and technical discussions are set up.
Resource specification form (Word Document) is available to be filled by the participants. List of contact persons and an updated list of DataGrid Testebed resources are available as well.
A Globus link was successfully established between Uppsala and Lund. The ellert.tsl.uu.se single machine was connected to the Lund Grid cluster through the grid.quark.lu.se master node.
Initially we experienced some problems setting up the connection due to the firewall of the Uppsala University. Although they were not very happy, the system administrators were convinced that for experimental purposes the firewall should be opened between the two sites. After this everything worked fine in both directions.
For the future it might be a good idea to configure the gatekeepers to use a restricted range of ports for their return connections by setting the GLOBUS_TCP_PORT_RANGE and GLOBUS_UDP_PART_RANGE environment variables. By doing this it will no longer be necessary to open the firewall for traffic on all ports, but only for a limited number of ports. This is probably safer, and could possibly be more acceptable to the security people.
The alpha release 4 of the Globus Datagrid software, obtained from the Globus CVS, was successfully installed on the Lund Grid Cluster. The fork and the PBS jobmanagers were both configured on the gatekeeper. The gatekeeper is called grid.quark.lu.se and the default ports were used for Globus services.
NorduGrid Certificate Authority has been set up.
The Lund cluster is up and ready for testing.
