v59 v60 1 1 [[PageOutline]] 2 2 3 = = About Cypress ==3 = About Cypress = 4 4 5 5 Cypress is Tulane's newest HPC cluster, offered by Technology Services for use by the Tulane research community. It is a 124-node cluster, with each node providing dual 10-core 2.8 GHz Intel Xeon E5-2680 v2 CPUs, 64 GB of RAM, and dual Xeon Phi 7120P coprocessors. Nodes are interconnected on a 40 Gigabit Ethernet network using a single Dell Z9500 Ethernet Fabric Switch. 6 6 7 = = Getting an account ==7 = Getting an account = 8 8 9 9 All accounts must be associated with a Tulane faculty member who is the Principal Investigator (PI) of his/her research group. Please have your PI [[#GettinghelpContactus|contact us]] to establish a group on Cypress. (If some members of your group have Cypress accounts, your group is already established.) After your group is established, visit Tulane Service Now at: … … 13 13 to request an account. After logging in with your Tulane credentials, you'll see the "Tulane IT Portal" where you'll select "Request Something". From the categories in the left sidebar select "Cypress HPC", then "Cypress HPC Request" and fill out the form. (See also https://it.tulane.edu/acceptable-use-policy.) 14 14 15 = = Account Deactivation ==15 = Account Deactivation = 16 16 17 17 Cypress accounts can be deactivated due to inactivity or change of a user's status at Tulane. See [[cypress/accounts|Account Deactivation]] 18 18 19 = = Logging in to Cypress after your account is created ==19 = Logging in to Cypress after your account is created = 20 20 21 21 Cypress provides two login nodes: … … 32 32 Note that this will also change your password for your e-mail and Single Sign On applications. 33 33 34 = = Storage: home directory ==34 = Storage on Cypress = 35 35 36 Your home directory on Cypress is intended to store customized source code, binaries, scripts, analyzed results, manuscripts, and other small but important files. This directory is limited to 10 GB (10,000 MB),~~ and is backed up~~. To view your current quota and usage, run the command: 36 For information on the following, see [wiki:FileTransfer#StorageonCypress Storage on Cypress]. 37 37 38 {{{ 39 quota -f /home 40 }}} 38 * '''Home''': Storage on your home directory and quotas 39 * '''LUSTRE''': Storage on your group's shared LUSTRE project directory and quotas 40 * '''Admin tasks''': Administrative tasks performed at regular intervals for the following 41 * '''Quota reconciliation''': quota reduction due to under use 42 * '''Data retention''': data removal due to inactivity 41 43 42 Please do not use your home directory to perform simulations with heavy I/O (file read/write) usage. Instead, please use your group's Lustre project directory. 43 44 == Storage: Lustre group project directory == 45 46 Cypress has a 699 TB Lustre filesystem available for use by active jobs, and for sharing large files for active jobs within a research group. The Lustre filesystem has 2 Object Storage Servers (OSSs) which provide file I/O for 24 Object Storage Targets (OSTs). The Lustre filesystem is available to compute nodes via the 40 Gigabit Ethernet network. The default stripe count is set to 1. 47 48 Allocations on this filesystem are provided per project/research group. Each group is given a space allocation of 1 TB and an inode allocation of 1 million (i.e. up to 1 million files or directories) on the Lustre filesystem. If you need additional disk space to run your computations, your PI may request a quota adjustment. To request a quota adjustment, please provide details and an estimate of the disk space used/required by your computations. Allocations are based on demonstrated need and available resources. 49 50 The Lustre filesystem is not for bulk or archival storage of data. The filesystem is configured for redundancy and hardware fault tolerance, but is not backed up. If you require space for bulk / archival storage, please submit a request for consultation [[https://tulane.service-now.com/tulaneit?id=sc_cat_item&sys_id=277b5905db004c10e8ce5bd2ca961945&sysparm_category=8d648d93dbc44c10f460562bdc9619ad&catalog_id=-1|here]], and we will take a look at the available options. 51 52 === Data Retention on Lustre === 53 54 Data on Lustre can be subject to removal due to inactivity or in the event of detected over usage. See [[cypress/DataRetention|Data Retention on Lustre]]. 55 56 === Checking quotas on Lustre === 57 58 Your group's Lustre project directory will be at: 59 60 {{{ 61 /lustre/project/<your-group-name> 62 }}} 63 64 "your-group-name" is your Linux group name, as returned by the command "id -gn". Your group is free to organize your project directory as desired, but it is recommended to create separate subfolders for different sets of data, or for different groups of simulations. 65 66 To view your group's current usage and quota, run the command: 67 68 {{{ 69 lfs quota -g `id -gn` /lustre 70 }}} 71 72 To view your own usage, you can run: 73 74 {{{ 75 lfs quota -u `id -un` /lustre 76 }}} 77 78 79 == Software on Cypress == 44 = Software on Cypress = 80 45 81 46 Software on Cypress is organized using the [[http://modules.sourceforge.net/|Environment Modules]] (modules) package. The modules command is "module".
