All Peregrine 1 nodes consist of identical hardware. All Peregrine 1 nodes have 16 processor cores, 32 GB RAM, and 56 Gbps Infiniband interconnects.
|Sub-Cluster||Number of Nodes||Processors per Node||Cores per Node||Memory per Node||Interconnect||TeraFLOPS|
|Peregrine 1-A||29||Two 8-Core Intel Xeon-E5||16||32 GB||56 Gbps FDR Infiniband||8.4|
Peregrine 1 nodes run Red Hat Enterprise Linux 6 (RHEL6) and use Moab Workload Manager 7 and TORQUE Resource Manager 4 as the portable batch system (PBS) for resource and job management. Peregrine 1 also runs jobs for BoilerGrid whenever processor cores in it would otherwise be idle. The application of operating system patches occurs as security needs dictate. All nodes allow for unlimited stack usage, as well as unlimited core dump size (though disk space and server quotas may still be a limiting factor).

On Peregrine 1, ITaP recommends the following set of compiler, math library, and message-passing library for parallel code:
To load the recommended set:
$ module load devel
To verify what you loaded:
$ module list
