Please note, New York Blue/L has been decommissioned and these web pages have not yet been updated to reflect its removal from service. The New York Blue/P is now one rack and remains in service. The BNL Blue Gene/Q also remains in service.
The only way to access Blue Gene computing resources remotely (outside the Blue Gene network enclave) is through the Blue Gene ssh gateways. Even users connecting from inside the BNL campus network need to go through the gateways. ssh tunneling allows one-hop access (logins and file transfers) to the Front-End nodes and the Visualization cluster.
