Accessing Clusters

Set up your SSH agent and use your uploaded SSH key to log into an SSH gateway, then connect to the appropriate interactive/submit node for your project/experiment; optionally configure ~/.ssh/config for more convenient access:

HPC (high performance computing) cluster(s) : Slurm:

Cluster	Host(s)
IC2	Intel CPU: `ic2submit01` AMD CPU / LQCD: `ic2submit02`

HTC (high throughput computing) pools : HTCondor:

Group	Host(s)
STAR	General purpose interactive: `starsub[01-07]` Special/production (selected users): `starprod[01-02],starcrs01`
PHENIX	General purpose interactive: `phnxuser[01-04]` Special/production (selected users): `phnxprod[01-02]`
sPHENIX	General purpose interactive: `sphnxuser[01-08]` Special/production (selected users): `sphnxprod[01-04]` Development (selected users): `sphnxdev01`
ATLAS T3	General purpose interactive: `attsub[01-08]`
EIC	General purpose interactive: `eicsub[01-02]`
DUNE	General purpose interactive: `dunesub[01-02]`
Astro	General purpose interactive: `astrosub[01-02]`
General interactive (Belle II, NPPS, Theory, BRAHMS, Misc, etc.)	General purpose interactive: `spoolsub[01-04]`

Example ~/.ssh/config¶

Using ProxyJump to automatically bounce through the gateway to internal hosts:

# can also then just 'ssh ssh.sdcc' as an efficient shortcut
Host ssh.sdcc ssh.sdcc.bnl.gov
    User <your_sdcc_username>
    Hostname ssh.sdcc.bnl.gov

# can then just 'ssh <short_hostname>' for these hosts, eg. 'ssh phnxuser03'
Host ic2submit* astrosub* attsub* dunesub* eicsub* phnxprod* phnxuser* phnxuser* sphnxdev* sphnxprod* sphnxuser* spoolsub* starprod* starsub* 
    User <your_sdcc_username>
    ProxyJump ssh.sdcc.bnl.gov

# or 'ssh <hostname>.sdcc.bnl.gov' for an .sdcc.bnl.gov internal host
Host *.sdcc.bnl.gov !ssh* !cssh*
    User <your_sdcc_username>
    ProxyJump ssh.sdcc.bnl.gov
