The Grid Community Toolkit has released new GSI-OpenSSH packages with High Performance SSH/SCP (HPN) patches in EPEL 7 and EPEL 8. HPN patches improve remote file copy performance for scp. Our XSEDE GCT GSI-SSH documentation has been updated to reflect the new GCT GSI-SSH release at https://software.xsede.org/production/gsi-openssh-server-xsede/INSTALL.
GCT GSI-OpenSSH includes HPN starting with these versions:
GSI-OpenSSH is a modified version of OpenSSH that adds support for GSI authentication and credential forwarding (delegation), providing a single sign-on remote login and file transfer service. GSI-OpenSSH also includes High Performance Networking (HPN) updates for OpenSSH from the Pittsburgh Supercomputing Center, iSSHD/NERSCmod (run-time disabled by default), and TCP wrapper support.
