Nautilus, an SGI Altix UV 1000 system, is the centerpiece of NICS Remote Data Analysis and Visualization Center (RDAV). It has 1024 cores (Intel Nehalem EX processors), 4 terabytes of global shared memory, and 8 GPUs in a single system image. Nautilus currently has a 427 TB Lustre file system, a CPU speed of 2.0 GHz, and a peak performance of 8.2 Teraflops.
The primary purpose of Nautilus is to enable data analysis and visualization of data from simulations, sensors, or experiments. Nautilus is intended for serial and parallel visualization and analysis applications that take advantage of large memories, multiple computing cores, and multiple graphics processors. Nautilus allows for both utilization of a large number of processors for distributed processing and the execution of legacy serial analysis algorithms for very large data processing by large numbers of users simultaneously.
Nautilus hardware support is provided 8:00am – 5:00pm ET. Issues occurring on nights and weekends will be addressed the following business day.
