Aspera

Aspera is IBM's high-performance file transfer software. It allows for the transfer large files and data sets with predictable, reliable, and secure delivery, regardless of file size or transfer distance, from a site which has the Aspera server running. The National Center for Biotechnology Information (NCBI) recommends the use of Aspera for transfer of data sets from their site.

At the CHPC, Aspera Connect is available as the "aspera" module.

To Use

To use the command-line client (Apsera Connect), run module load aspera. To see all options, run ascp --help. Typically, if you receive instructions to download or upload files with Aspera, you will be provided with an example command or detailed instructions for specifying a key file or other options. If you need assistance with your transfer, please include this information when contacting the CHPC.

 

Example (NCBI public database and standard connection info):

module purge
module load aspera/4.2.12
env ASPERA_SCP_PASS=743128bf-3bf3-45b5-ab14-4602c67f2950 ascp -QT -l500m -i /uufs/chpc.utah.edu/sys/installdir/aspera/4.2.12/connect/etc/aspera_tokenauth_id_rsa anonftp@ftp.ncbi.nlm.nih.gov:1GB /tmp/
