+ | ======Your Desktop====== | ||
+ | The Observatory has a standard Linux Workstation of which the configuration is updated regularly. The major aim for this Workstation is to provide you with ample computer resources on your desk for most of you daily scientific work. For extremely heavy computing we have an HPC cluster, special purpose science servers and a Bulk Storage environment. | ||
+ | =====Configuration===== | ||
+ | The current standard hardware configuration is: | ||
+ | Fujitsu M740 | ||
+ | One Intel(R) Xeon(R) CPU E5-1650v3 | ||
+ | 16GB RAM | ||
+ | 1 256GB SSD drive with Fedora Core OS | ||
+ | 3 4TB disks in RAID5 configuration, | ||
+ | 1 DVD RW | ||
+ | 27" 2560x1440 Screen | ||
+ | |||
+ | |||
+ | The actual disk configuration is as follows: | ||
+ | /data1 175 GB on the SSD | ||
+ | /data2 7.7TB RAID5 on the 3 4TB disks | ||
+ | |||
+ | =====How to use==== | ||
+ | Before you can actually use your Workstation you need to realize that you are in a networked environment. This means that your desktop computer contributes to the whole of Observatory computing and that it provides you a personal entry point from remote. | ||
+ | |||
+ | ===Personal data==== | ||
+ | {{personaldata.jpg? | ||
+ | |||
+ | The home directory is there for you to store important information you never want to loose. But is is rather small in size as we cannot affort to backup the sum of all users home directories when that exceeds practical size limits. To store your science data you should use the local disk structure, e.g. /data2 for saving data securely. | ||

+ | |||
+ | On the network there are several storage devices to save data you are not using temporarily. Each group at the Observatory has a set of such disks. Please contact your group member for details. | ||
+ | |||
+ | ===Network access== | ||
+ | Your data disks are available over the network, from each and every Workstation at the Observatory through the following mechanism. | ||

+ | === Always on! === | ||
+ | Because of remote logins and remote disk access, the Linux desktops should always be left on. Not only for your convenience and that of your co-workers with whom you may share data on the disk, but also to allow system maintainance and updates. | ||
+ | |||
+ | === Operating system === | ||
+ | Currently, our desktops run Linux (Fedora 27) and/or Windows 10. |
