Cluster systems are the main hardware resource in A*CRC. Ranging in peak performance from 1 to 35 TFLOPs, these systems are meant to host a variety of tasks from large number of small (serial) jobs to large, multi-thread, multi-task or/and large memory-footprint programs that require very large resources.
Here is the detailed list of the computing resources of A*CRC:
