After much delay from vendor setbacks, we are excited to announce the opening of the Negishi Early User Program (EUP). User logins are enabled.

Participating research partners are encouraged to check their user and group account pages on the RCAC website to see the their current allocation, and add group members to their Negishi queue on the website to grant them access the system in the usual manner.

During the EUP, there will be an accelerated maintenance schedule, consisting of downtime every Wednesday, for which we will post regular updates. While we hope to limit reboots to these maintenance windows, it may occasionally be necessary to initiate emergency reboots at other times.

Users will need to submit jobs to the standby queue, as dedicated queues are still in the process of being defined in the scheduler. Currently, Negishi has available all its login nodes, one rack of compute nodes, and all file systems. The remaining compute nodes will be coming online soon pending the necessary equipment.

EUP participants have been assigned designated RCAC staff consultants and primary contacts for the duration of the Negishi EUP. Please send issues, feedback, and requests to rcac-help@purdue.edu with [Negishi-EUP] in the subject line and CC your designated consultant.

All documentation for Negishi can be found in the User Guide. A list of notable differences between Negishi and earlier RCAC clusters is summarized in this FAQ.

Please note that Negishi has its own separate home file system distinct from the other community clusters, so you will be met with an empty directory when first accessing the system.

Available features:

• SSH to login nodes,
• Home, Scratch, and Data Depot file systems,
• SLURM job scheduling (with modified limitations),
• Core applications with module files,
• Globus and scp/sftp/rsync file transfers,
• User-facing tools (e.g., slist, myquota, hsi/htar),

Not yet available:

• ThinLinc (remote desktop),
• Open OnDemand (web interface),
• Connecting to file systems via Windows Network Drive / SMB,
• Some applications (e.g., ANSYS, Gaussian).

We look forward to your feedback and hope Negishi will prove a useful resource for your research! For any questions or comments please contact rcac-help@purdue.edu with [Negishi-EUP] in the subject line.
