We are the theoretical and computational research group, therefore the main research facility is the supercomputing facility. Our group has accumulated 12 years experience of constructing and operating the supercomputing PC-cluster since 1999 by ourselves in stead of purchasing directly the main frame supercomputer which costs about 100 times more expensive than the ones we made by ourselves. In fact we were the first group in Korea who constructed 64 nodes-supercomputing PC-cluster on 1999 and has led the Korean supercomputing community. Since then we have accumulated the leading edge technology of supercomputing PC-cluster. As a consequence we are now equipped with 296 nodes supercomputing PC-cluster (864 CPU-cores & 43,040 GPU/CUDA-cores) which amount to the total clock speed of 143 Tflops. The pictures below show the supercomputing PC-cluster in the full operation now at our Center for Proteome Biophysics, DGIST. This supercomputing facility greatly facilitates our worldwide competitive research on the theoretical/computational protein physics.
