CARC supercomputers and clusters

Computational Resources at a Glance

Overview of computational resources at the Center, including OS, libraries, schedulers, etc.

Community Machines

 
 
The CARC houses a total of about 5 Tflops/sec (peak) of computing power and just under 100 TB of storage, distributed across various systems that include those of the resident research groups.  Of this storage, 23 TB are accessible to the general research community.  These latter data spaces are backed by an in-house developed Amanda-based system featuring 30 TB of LTO tape storage rotated through a 15 TB robotic tape library system (tapes not in the robot are stored off-site.)  Major supercomputer resources in the CARC are shown in Table 1.
 
Also available on a limited basis to CARC researchers is access to the computational assets of the recently-established state-wide supercomputing center, the New Mexico Computing Applications Center.  The NMCAC is managed by a consortium of the three New Mexico research universities (UNM, New Mexico Tech, NMSU), Los Alamos National Laboratory and Sandia National Laboratories. 

The CARC-resident ARTS Lab maintains a 15 foot diameter SkySkan Dome Theater display system with six projectors and five-channel audio, switchable between an 8-node dual-CPU Windows-based rendering farm (with 10 TB of dedicated RAID storage) and an 16-core 32 GB RAM Mac Pro real-time rendering engine with advanced Nvidia graphics capabilities.
