Technical Specs

ALPS is short for “Advanced Large-scale Parallel Supercluster” (also known as “御風者” in Chinese). It is a supercomputer that offers an aggregate performance of over 177 TFLOPS. The system uses the AMDR Opteron 6100 processors, and has a total of 8 compute clusters, 1 large memory cluster, and over 25,600 compute cores.

ALPS is designed to support a wide range of applications — so many that NCHC could only begin to fathom the jobs that could potentially be run across it. APLS is also designed to function as a test bed for new application design and research; support for open source and academic-specific applications is a must. To offer the most robust level of support, the system was first planned with every angle in mind — not simply raw compute performance, and not necessarily best performance per watt.

> Queuing System

NCHC users specify one of the following submit classes to queue jobs. Upon submission the job is routed to the appropriate LSF class according to the following criteria.

Queue Name CPU(s)/job Max CPUs/user (CPU/Run)time limit/job
serial 1 20 12 days
12cpu 2 ~ 12 120 8 days
48cpu 13 ~ 48 240 6 days
192cpu 49 ~ 192 768 5 days
384cpu 193 ~ 384 768 3 days
768cpu 385 ~ 768 1536 2 days
short 128 128 2 days
medium 128 128 6 days
long 128 128 10 days

All batch jobs must be submitted to a valid submit class. If the class doesn“t exist, job will be terminated and an error message will be issued.
