The system will reside at the Research Center for Modeling and Simulation (RCMS), which was acquired by Pakistan’s National University of Sciences and Technology (NUST) through a grant provided by the country’s Ministry of Science and technology. An inauguration event was held where RCMS Principal, Sikandar Hayat noted that the new system is the fastest GPU-based parallel computer in the country.
The system, known as ScREC, is named after the university’s supercomputing research and education center. The cluster consists of 66 nodes equipped with a total of 30,992 cores. The NUST site breaks down the components as follows: 32 dual-socket quad-core nodes, 32 NVIDIA GPUs, a QDR InfiniBand interconnect, and 26.1 TB of storage. Specifics on the CPU or GPU parts were not provided.
While Linpack performance has not been posted, the system runs at a peak of 132 teraflops. Given that most GPU-accelerated TOP500 systems only achieve about a 50 percent Linpack yield of peak performance (depending upon the CPU-GPU ratio and interconnect), the system should deliver at least 60 Linpack teraflops. That would place the system in the current list, giving Pakistan a slot in the TOP500. Unfortunately the rankings are a moving target, and the June update may well exclude sub-60-teraflop machines. The slowest supercomputer on the current TOP500 is at 51 teraflops.
ScREC will be used to assist NUST with research in the areas of computational biology, computational fluid dynamics, image processing, cryptography, medical imaging, geosciences, computational finance, and climate modeling. Specifically, RCMS is currently developing a direct simulation Monte Carlo (DSMC) method for subsonic nanoscale gas flows. Other projects include external flow analysis of heavy vehicles to reduce fuel consumption, and numerical investigation on performance and stability of axial compressors used in aircraft engines and gas turbines.
In a welcome address, Rector Nust Engr Muhammad Asghar said, “This will give an impetus for collaborative research between universities and other research organizations within the country and abroad.” and explained that the new facility will inspire scholars studying abroad to return to Pakistan.
Pakistan’s investment in terascale computing exhibits a willingness to promote scientific research – a forward-leaning strategy for a developing nation on the cusp of becoming industrialized. Unlike India’s HPC plans, Pakistan is not attempting to join the ‘supercomputing elite’ here, but rather to promote science collaborations, while creating an incentive for Pakistani researchers and engineers who work abroad to return to the country.
