What hosts are part of the cluster?The cluster currently contains six hosts: storm0.scd.ucar.edu, storm1.scd.ucar.edu, storm2.scd.ucar.edu, storm3.scd.ucar.edu, storm4.scd.ucar.edu, and storm5.scd.ucar.edu 2. Are there any differences between the hosts?Functionally there is no difference between the systems. All of them have access to the same data areas, and the architectures are compatible. This means that code compiled on one node will run on any of the nodes. For a complete hardware description, see the Environment Overview document. 3. Do I have to move any of my files if I change which host I'm working on?No. All of the systems have access to a high-performance shared filesystem that serves all the data. You can log in to any node and your environment will be the same. 4. What compiler suite do I use to build my Fortran, C and C++ APIs?We recommend that you use the Intel compiler suite: ifort (Fortran 77 & 90), and icc (C and C++). There are setup files available for each of these. See the Compiler Hints & Tips document for more information. Like many other common utilities, you'll find these compilers in /fs/local/bin. 5. What file systems are available?You can find a list of the file systems available on the cluster on the File System Layouts & Policy page. Some of these file systems are only mounted when they are in use, so a "df" command will show you ones that are currently in use, but will not show you all file systems that are available. 6. What commercial applications are available?We maintain a list of currently supported applications on the Supported Applications page. You will find these applications in /fs/local/bin. 7. Can I run OpenGL applications remotely?Yes. We support Sun's VirtualGL VNC server and TurboVNC client to allow you to use the graphics hardware in the cluster from a remote location. More information on service is avaiable on the Remote Visualization page. 8. How do I check my quotas?You can find the different quota commands used to check your quota usage on the Checking Your Quota Usage page. |
