There are several methods for transferring files to HPCC depend on tier and consequently file system used. The resources from basic and advanced tier are attached to DSMS file system as it described in figure 1. above. Thus the users utilizing resources from these tiers may transfer files via Globus online or file transfer node. In addition The users on basic and advanced tier use r the DSMS can be transferred via:
- • Globus Online: The preferred method for large files, with extra features for parallel data streams, auto-tuning and auto-fault recovery. Globus online is to transfer files between systems—between the CUNY HPC Center resources and XSEDE facilities, or even users’ desktops. A typical transfer rate ranges from 100 to 400 Mbps.
- Details on connecting via Globus can be found here.
- • cea.csi.cuny.edu: Only Secure FTP (SFTP) can be used to transfer files to cea.csi.cuny.edu. Each of the servers is mounted on cea under its own name. Thus the users could place their files on particular server simply by preceding /scratch with /<name of the server> e.g. sftp> put TEST.txt /penzias/scratch/john.doe/TEST2.txt
- • iRODS: The data grid/data management tool provided by CUNY HPC Center for accessing the SR1 resource. iRODS clients (iput, iget, irsync) provide a data transfer mechanism featuring bulk upload and parallel streams.
