Globus is a software tool to transfer files across the web in a reliable, high-performance and secure way. It provides fault-tolerant, fire-and-forget data transfer using simple web (or command line) interfaces. It is appropriate for transferring very large files and datasets.
We have a Globus Connect endpoint (currently) named umnphys#data which lets you access Physics data storage.
First you need to create a free, Globus account:
/DC=org/DC=cilogon/C=US/O=University of Minnesota/CN=Your Name A12345
Note that this particular process is specific to our system in Physics; other places may handle it differently. For the MSI endpoint, you should send your certificate details and MSI account name to
To transfer files between the Physics cluster and other endpoints such as MSI.
/data/gammaray) - the path
/dataitself is not a writable location.
To transfer files between endpoints, select a file or directory from each list, then click one of the large arrow buttons to tell Globus the desired direction of the transfer.
You will receive an automatic email from Globus Notification (firstname.lastname@example.org) when the file transfer has completed. To have Globus show you the status and history of your file transfers, from its Go To pull-down menu, select View Transfers.
If you want to transfer files to or from your local desktop (or laptop) machine, you need to download and install the Globus Connect software (one-time). You will need to do this step on each computer whose files you want to transfer using Globus.
After that, the procedure is similar to that described above. If you are running Globus Connect, the first name in the list of available endpoints is your local computer, though you can select any site where you have an account.
Registering your certificate for the Physics endpoint subscribes you to a mailing list
email@example.com, where we'll send any information on changes to the system (the list is also open for subscribers to post discussion items). As usual for automatic physics lists, if you don't want to see these messages you can set it to “nomail” in MyPhys.
The transfer speed will depend greatly on the nature of the data set. For example, the number of parallel streams initiated is dependent on the size of the files being transferred. 2 streams for files less than 50MB, 4 streams for files between 50Mb and 250MB and 8 streams for files >250MB.
To use UDT instead of TCP as the tranfer protocol, put 'useudtplease' in the 'Label this Transfer' box (this may be useful for very distant transfers with high latency (BDP) on the network path).
