Users are encouraged to log in and make use of the new facilities.

To connect from a Mac you will need to install <a href=\"https:\/\/www.xquartz.org\/\">XQuartz<\/a> before X11 forwarding will work with the native <em>Terminal<\/em> app.\u202f If you are using Linux, including our\u202f<a href=\"https:\/\/research.reading.ac.uk\/act\/knowledgebase_category\/desktops\/\">Linux Remote Desktop Service<\/a>, SSH and X11 forwarding should work without any additional configuration.<\/p>\n<p><strong>If you need to connect from an off-campus machine, the available options are described <a href=\"https:\/\/research.reading.ac.uk\/act\/knowledgebase\/connect-from-outside-of-campus\/\">here<\/a>.<\/strong><\/p>\n<p>&nbsp;<\/p>\n<h2>Interactive computing and batch jobs<\/h2>\n<p>Interactive computing and batch jobs are analogous between the two clusters. For more information, refer to the RACC user guides on <a href=\"https:\/\/research.reading.ac.uk\/act\/knowledgebase\/racc-login-and-interactive-computing\/\">interactive computing<\/a> and <a href=\"https:\/\/research.reading.ac.uk\/act\/knowledgebase\/racc-batch-jobs\/\">batch jobs<\/a>. It might be that there are some<\/p>\n<p><strong>Background jobs and cronjobs are not permitted on the login nodes.<\/strong> If you need to run a cron job, please use our <a href=\"https:\/\/research.reading.ac.uk\/act\/knowledgebase\/cronjobs-on-the-academic-computing-cluster\/\">cron job node racc-cron<\/a>.<\/p>\n<p>&nbsp;<\/p>\n<h2>Storage<\/h2>\n<p>RACC2 sees the same storage as the RACC. This includes user home directories, Research Data Storage and scratch storage.<\/p>\n<p>The research data storage volumes are mounted under \/storage and scratch storage volumes are provided under \/sratch2 and \/scratch3.<\/p>\n<p>Please note that <strong>data in scratch space is not protected<\/strong> and it might be periodically removed to free up space (right now periodic removals are not implemented). Scratch storage should only be used for data which you have another copy of or that can be easily reproduced (e.g. model output or downloads of large data sets). User directories will be created on request when using scratch and not other types of data storage is justified.<\/p>\n<p>&nbsp;<\/p>\n<h2>Software installed on RACC2<\/h2>\n<p>Software on RACC2 is also\u00a0managed by environmental modules, see <a href=\"https:\/\/research.reading.ac.uk\/act\/knowledgebase\/accessing-software-on-the-cluster\/\">our article on how to access software on the cluster<\/a> for more information. The modules available on the RACC2 are not the same modules as those available on the RACC.<\/p>\n<p>If you notice software that has previously been available on the RACC but it&#8217;s missing from the modules on RACC2, check that it&#8217;s available from command line. We have a broader range of software packages and libraries available on RACC2 directly from command line without loading modules. If you do find that anything is missing, that we should be providing some software centrally or that something isn&#8217;t working as expected, please let us know by <a href=\"https:\/\/uor.topdesk.net\/\">raising a ticket to DTS.<\/a><\/p>\n<p>You can find further useful, software specific information in these articles: <a href=\"https:\/\/research.reading.ac.uk\/act\/knowledgebase\/python-on-the-academic-computing-cluster\/\">Python on the Academic Computing Cluster<\/a> and <a href=\"https:\/\/research.reading.ac.uk\/act\/knowledgebase\/running-matlab-scripts-as-batch-jobs\/\">Running Matlab Scripts as Batch Jobs<\/a>.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction to the new cluster  The new Reading Academic Computing Cluster (RACC2) is now available for use.
