This also applies if you want “only” to use the GPU machines!

As Hypatia's HTCondor headnodes are public ones, to access Hypatia from outside you will need a personal Grid Certificate (often referred to as X.509 cert), and a gsi-enabled ssh client. Please see Grid Certificates and GSIssh for details. Also be aware that port 2222 must be used for gsissh access. (I know that recent macoses have issues with that, and I'm aware of the terrible state of gsi-openssh.)

There is no such limitation for access from the AEI internal network, you may use normal ssh (with a key pair) then.

With a valid AEI account, you may also use VPN (which effectively adds your computer to the internal network).

• (This is becoming obsolete:) Apply for a certificate if you don't have one yet (or it expired).
  • A LIGO certificate will do but will stop working the day you leave LIGO.
  • If you are employed by the AEI but not working for LIGO (or do not want to use the LIGO certificate), you may submit your request here. Fill in / print the PDF from the start page, and come and see me (or one of the other RAs) afterwards, to present your ID card or passport. Note that KIT is phasing out their service, which will be operated until May 2023.
• If you have your certificate ready, or are at the AEI (this includes VPN) you may apply for a user account.

• In the process of account creation, you will be added to the hypatia-users mailinglist - which will be used for any further discussion about Hypatia.

The greeting email is your confirmation that account setup has been finished.

• For external users only:
  • Will you join AEI in the near future? (If so, when?) (The rationale behind this is that information will be copied from AEI's user database, to avoid UID clashes)
  • Your preferred account name (if not defined by the above)
• For users with an AEI account, that username will be used by default (but you may change it - right now).

• Your full name (e.g. as shown in the LSC roster) contact details
• Your host (AEI staff member overseeing your activities) - important if you're a guest or about to leave soon
• Your email address (no googlemail please)
• LSC membership? (I can look this up in the roster, of course)
• If you got an AEI contract, I'll look up the expiration date, otherwise I'll make up one (extendable)
• If applicable: Your X.509 certificate subject (the one with “CN=Your Name”, can be the output of grid-cert-info -subject, or of grid-proxy-info -issuer if the output contains your name, please double-check)
• Send your ssh public key as an attachment (unless you prefer to use GSIssh only)

• For approval, please provide the scientific reason, and an estimate of the usage of the cluster.

Once again: We're using gsissh to access the public port 2222 on the head nodes. ssh access to port 22 is only open from within the AEI network.

Some initial information about Hypatia can be found at https://hypatia.aei.mpg.de

To apply for a Hypatia account, send a request to hpc-support@aei... with the necessary information, and CC alessandra.buonanno@aei... for approval!

For access to the GPU machines, also jonathan.gair@aei... must approve.

Note: @aei… means @aei.mpg.de, email addresses have been truncated for spam protection!
