Tigressdata is a single computer with 80 hardware threads (40 cores), 768 GB of RAM and an NVIDIA P100 GPU. The system is intended for data analysis and remote visualization of data generated on the HPC clusters. Tigressdata can also be used for developing, debugging and testing codes.
System Configuration and Usage
As its name implies, tigressdata has fiber connectivity to /tigress (and /projects), which is the large archival storage system. There is also NFS connectivity to selected parallel or scratch storage spaces allocated to the Princeton clusters. Several commercial and open-source packages are installed on tigressdata.
Please be mindful that tigressdata is a shared resource for all users (i.e., there is no job scheduler). Use the htop command and see "Job Scheduling" below to monitor usage.
Accessing Files on Della, perseus and tiger
The figure below makes it clear that the /scratch/gpfs filesystems of della, perseus and tiger are accessible from tigressdata:
For example, to access files on della's /scratch/gpfs filesystem from tigressdata use the path /della/scratch/gpfs/<YourNetID>:
$ ssh <YourNetID>@tigressdata.princeton.edu $ ls /della/scratch/gpfs/<YourNetID>
The commands above also apply to perseus and tiger with the appropriate changes.
