From: Accelerating the scoring module of mass spectrometry-based peptide identification using GPUs

Node number CPU-cluster GPU-cluster
Scoring Pre-calculation Speedup percentage Scoring Pre-calculation Speedup percentage
one 32587 s 242 s   502 s 8 s  
two 17997 s   89.3% 279 s   87.4%

four 8991 s   88.2% 136 s   87.1%
  1. Note: speedup percentage equals to: one scoring time/ (N node scoring time + pre calculation time)/N.
