It is run by the Institute for Computational Research in Engineering and Science, which is a function of the [http://www.cs.ksu.edu/ Computer Science] department. Beocat is available to any educational researcher in the state of Kansas (and his or her collaborators) without cost. Priority access is given to those researchers who have contributed resources.\n\nBeocat is actually comprised of several different cluster computing systems\n* \"Beocat\", as used by most people is a [[wikipedia:Beowulf cluster|Beowulf cluster]] of CentOS Linux servers coordinated by the [https://slurm.schedmd.com/ Slurm] job submission and scheduling system. Our [[Compute Nodes]] (hardware) and [[installed software]] have separate pages on this wiki. The current status of this cluster can be monitored by visiting [http://ganglia.beocat.ksu.edu/ http://ganglia.beocat.ksu.edu/].\n* A small [[wikipedia:Openstack|Openstack]] cloud-computing infrastructure\n\n== How Do I Use Beocat? ==\nFirst, you need to get an account by visiting [https://account.beocat.ksu.edu/ https://account.beocat.ksu.edu/] and filling out the form. In most cases approval for the account will be granted in less than one business day, and sometimes much sooner. When your account has been approved, you will be added to our [[LISTSERV]], where we announce any changes, maintenance periods, or other issues.\n\nOnce you have an account, you can access Beocat via SSH and can transfer files in or out via SCP or SFTP (or [https://www.globus.org/ Globus Connect] using the endpoint ''beocat#beocat''). If you don't know what those are, please see our [[LinuxBasics]] page. If you are familiar with these, connect your client to headnode.beocat.ksu.edu and use your K-State eID credentials to login.\n\nAs mentioned above, we use Slurm for job submission and scheduling. If you've never worked with a batch-queueing system before, submitting a job is different than running on a standalone Linux machine. Please see our [[SlurmBasics]] page for an introduction on how to submit your first job. If you are already familiar with Slurm, we also have an [[AdvancedSlurm]] page where we can adjust the fine-tuning. If you're new to HPC, we highly recommend the [http://www.oscer.ou.edu/education.php Supercomputing in Plain English (SiPE)] series by OU. In particular, the older course's streaming videos are an excellent resource, even if you do not complete the exercises.\n\n<H4>Get an account at  [https://account.beocat.ksu.edu/ https://account.beocat.ksu.edu/]<BR>\nRead about  [[Installed software]] and languages<BR>\nLearn about Slurm at [[SlurmBasics]] and [[AdvancedSlurm]]<BR>\n</H4>\n\n== Running Software on Beocat ==\nRunning software on Beocat involves submitting a small job script to the scheduler which will use the information in that job script to allocate the resources your job needs then start the code running.  Click on the links below to see examples of how to run applications written in some common languages used on high-performance computers.  The first link for OpenMPI also provides general information on loading modules and using <B>sbatch</B> and <B>scancel</B> to submit and cancel jobs.\n* Running an [[Installed software#OpenMPI|MPI job]]\n* Running an [[Installed software#R|R job]]\n* Running a [[Installed software#Python|Python job]]\n* Running a [[Installed software#MatLab compiler|Matlab job]]\n\n== Writing and Installing Software on Beocat ==\n* If you are writing software for Beocat and it is in an installed scripting language like R, Perl, or Python, please look at our [[Installed software]] page to see what we have available and any usage guidelines we have posted there.\n* If you need to write compiled code such as Fortran, C, or C++, we offer both GNU and Intel compilers. See our [[FAQ]] for more details.\n* In either case, we suggest you head to our [[Tips and Tricks]] page for helpful hints.\n* If you wish to install software in your home directory, we have a [[Training Videos#Installing_files_in_your_Home_Directory|video]] showing how to do this.\n\n==  How do I get help? ==\nYou're in our support Wiki now, and that's a great place to start! We highly suggest that before you send us email, you visit our [[FAQ]]. If you're just getting started our [[Training Videos]] might be useful to you.\n\nIf your answer isn't there, you can email us at [mailto:beocat@cs.ksu.edu beocat@cs.ksu.edu]. ''Please'' send all email to this address and not to any of our staff directly. This will ensure your support request gets entered into our tracker, and will get your questions answered as quickly as possible. Please keep the subject line as descriptive as possible and include any pertinent details to your problem (i.e. job ids, commands run, working directory, program versions,.. etc). If the problem is occurring on a headnode, please be sure to include the name of the headnode. This can be found by running the <tt>hostname</tt> command.\n\nWe are also available on IRC on the [http://freenode.net/using_the_network.shtml freenode chat servers] in the channel #beocat. This is useful ''especially'' if you have a quick question, as you'd be surprised the times when at least one of us is around. If you do have a question be sure to mention '''m0zes''' and/or '''kylehutson''' in your message, and it should grab our attention. Available from a web browser [[Special:WebChat|here.]]\n\nFor in person help, we offer a weekly open support session as mentioned in our calendar down below. Alternatively, we can often schedule a time to meet with you individually. You just need to send us an e-mail and provide us with the details we asked for above.\n\n<H4>\nAgain, when you email us at [mailto:beocat@cs.ksu.edu beocat@cs.ksu.edu] please give us the job ID number, the path and script name for the job, and a full description of the problem.  It may also be useful to include the output to 'module list'.\n</H4>\n\n== Twitter ==\nWe now have [https://twitter.com/KSUBeocat Twitter]. Follow us to find out the latest from Beocat, or tweet to us to find answers to quick questions. This won't replace the mailing list for major announcements, but will be used for more minor notices.\nHere are some recent tweets:\n<ShoogleTweet limit=\"6\">KSUBeocat</ShoogleTweet>\n\n== How do I get priority access ==\nWe're glad you asked! Contact [mailto:dan@ksu.edu Dr. Dan Andresen] to find out how contributions to Beocat will prioritize your access to Beocat.\n\n== Policies ==\nYou can find our policies [[Policy|here]]\n\n== Credits and Accolades ==\nSee the published credits and other accolades received by Beocat [[Credits|here]]\n\n== Upcoming Events ==\n{{#widget:Google Calendar\n|id=hek6gpeu4bg40tdb2eqdrlfiuo@group.calendar.google.com\n|color=711616\n|view=AGENDA\n}}"
