How to copy files? Similar to using ssh to login, you can use sftp, scp, and rsync over ssh to copy files to a system on Xsede. If your files are on the Tufts compute cluster they will copy over to Xsede much faster than from a typical desktop, workstation or laptop on wifi or a wired 1GB network drop. Please feel free to contact Tufts staff to make sure your file copy procedures are as efficient as possible. **
- Is Globus supported at Tufts as a file transfer mechanism? Currently no though this is being examined. Globus is based upon GridFTP and allows for higher speed transfer, via multiple data paths, than typical tools such as scp, sftp, and rsync. This is of particular importance as files and datasets get larger. Globus also allows for disconnected transfer and restart of large file copies.

- Is Aspera supported at Tufts as a file transfer mechanism? As far as we know Aspera is not deployed on Xsede yet though it is being examined.
How do I chose between the Tufts HPC (High Performance Compute) cluster and Xsede? The decision is not mutually exclusive as both clusters are general purpose clusters running a wide variety of software for a an equally broad user base. Typically if you are running custom code it should be compiled individually for each system.
