Overview
In the world of HPC there is HPC new users are often unsure of the best ways to access their data, and frequent need to move and copy your files and folders data between locations.
This page covers various methods of performing these basic file operations.
SMB/CIFS Data Transfer over GUI - (AKA: “Map the drive, then just copy-paste”)
With so many complicated terms, acronyms, and learning how to use the command line, sometimes we all forget that you can still use a GUI (Graphical User Interface).
...
Search using the windows start search for file explorer, or click on the ‘File Explorer App’ from your start menu.
...
This will bring up a file explorer window. Select this PC from the menu pane on the right.
...
...
To map the location as a drive that you may re-access, click on the 3 dots at the top of your file explorer window and choose “map network drive”.
...
...
This brings up a new screen:
...
Choose a drive letter, then for the folder name, type in the following depending on the location of your data
...
If you are connecting from a computer only used by you or that you log into using your individual UWYO username and password, you can check the box to reconnect at sign-in.
...
Beartooth data storage corresponds to server name “tetoncreek-cifs” while Alcova data storage corresponds to server name “alcova”. If you’re not sure how what your exact project path is, you can e-mail arcc-help@uwyo.edu and ARCC staff members can provide guidance. Once the folder is mapped, you can ctrl+c, ctrl+v or drag and drop like you’re used to from any windows PC.
On a Mac:
Hit cmd+k, or Open Finder (top menu) ->
Go->
Connect to server:
.
...
In the ‘Connect to Server’ window that pops up, enter:
smb://<servername>.arcc.uwyo.edu/<pathto>/<yourproject>and click ‘Connect’.
When prompted for login credentials, enter uwyo\<your_username> in the username field, and <your UWYO password> in the password field, then connect.
Beartooth data storage corresponds to server name “tetoncreek-cifs” while Alcova data storage corresponds to server name “alcova”. Once you’re connected to the folder, you can cmd+c, cmd+v or drag and drop like you’re used to. If you’re not sure how what your exact project path is, you can e-mail arcc-help@uwyo.edu and ARCC staff members can provide guidance. Because there are several different options, this page can be thought of as an ARCC central reference for data access and transfer.
If you’re new to HPC, we recommend you begin with Graphical User Interface options as these tend to be more intuitive for new HPC users with minimal command line experience.
Graphical User Interface Options:
Mapping ARCC Storage as a network drive
Access to ARCC Storage with Globus
Access to you Beartooth Data in Southpass
Command Line Tools
Here are several command line tools to make managing files easier:
scp (Secure Copy)
Secure copy or SCP is a means of securely transferring computer files between a local host and a remote host or between two remote hosts. It is based on the Secure Shell (SSH) protocol. From the command line interface, the local host is always represented by the text before the $ in your command line prompt.
...
| Code Block |
|---|
$ scp -r /local/folder/. username@to_host:/remote/folder/ |
sftp
Secure Shell File Transfer Protocol is a command-line interface client program to securely transfer files using an encrypted Secure Shell connection. SFTP should not be confused with running an FTP client over an SSH connection.
Start the sftp interface: SFTP username@beartooth.uwyo.edu
Examples
This gets a txt file from Teton and moves it to the Local System:
get hello_world.txt destination_directoryThis puts a txt file from the Local System onto Teton:
put source_directory/hello_world.txt destination_directory
rclone
rclone is an updated and multithreaded version of the rsync utility, with robust capabilities.
functions as both a file synchronization and file transfer program
The rsync algorithm is a type of delta encoding and is used to minimize network usage. Zlib may be used for additional compression, and SSH or stunnel can be used for data security
Rsync is typically used to synchronize files and directories between two different systems.
For example, if the command rclone local-file user@beartooth.arcc.uwyo.edu:remote-file is run, rclone will use SSH to connect as the user to remote-host
Examples
To sync the contents of dir1 to dir2 on the same system:
rclone -r dir1/ dir2To sync with a remote system:
rclone -a ~/dir1 username@beartooth.arcc.uwyo.edu:destination_directory
FTP
FTP (File Transfer Protocol) is a network protocol for transmitting files between computers over Transmission Control Protocol/Internet Protocol (TCP/IP) connections. Within the TCP/IP suite, FTP is considered an application layer protocol.
Although some systems might have a ftp client installed directly on the system, due to various security concerns, and that the protocol is being deprecated, ARCC does not have a client installed.
As a starting point, see the Wiki entry that states “Throughout 2021, the two major web browser vendors removed this ability. Support for the FTP protocol was first disabled in Google Chrome 88 in January 2021,[4] followed by Firefox 88.0 in April 2021.[5] In July 2021, Firefox 90 dropped FTP entirely,[6] and Google followed suit in October 2021, removing FTP entirely in Google Chrome 95”.
Alternatives
Where users require an ftp client we can offer a number of alternatives:
curl: This is available directly on the system and offers ftp functionality.
Globus Online
Globus manages file transfers between two computer systems. It is ideal for large files and available for many institutional clusters and networks.
This document covers the basics of using Globus and provides external links to more detailed information.
If you’re a first time user or simply need a refresher, please refer to Globus’ excellent step by step guide.
Using Globus in Brief
Login to Globus' Web app.
Click “Login”.
To use UWyo’s organizational login, search for ‘University of Wyoming’.
Note that this step may be skipped if Globus still has you cached.
Enter or search for an endpoint or collection in the ‘Collection’ field or find recently used endpoints under ENDPOINTS in the left pane.
The Teton/Alcova collection is ‘ARCC Teton’.
Click ‘Transfer or Sync to…’ in the panel on the right side of the page.
Enter/find a second collection.
Browse to the appropriate source and destination folders in both collections.
Select the files/folders you wish to copy and click ‘Start’.
Click ‘Activity’ in the left pane to observe the transfer progress.
Globus file share instructions
See Globus' instructions on sharing data to learn how to create and share an upload/download repository that you can control access to.
Globus Connect Personal
Globus Connect Personal allows you to share and transfer files to and from your laptop or desktop computer. GCP supports the three primary OS’s. The default is for Mac; click the ‘Show me other supported operating systems’ toggle to download for Linux and Windows.
Note that GCP has a “High Assurance” option for Protected Health Information or Controlled Unclassified Information.
Globus Command Line Interface (CLI)
If you need to use a command line interface, please refer to Globus’ excellent step by step guide.
