The Numerical Algorithms Group (NAG, www.nag.com) announces new HPC performance milestones including up to 4 times better performance with multicore optimization for materials science and quantum Monte Carlo applications and reductions of up to 25% in runtimes with I/O tuning for an ocean modelling application. These are the early results of NAG's distributed Computational Science and Engineering (dCSE) support program for HECToR (UK's national supercomputing facility), which now consists of over 30 dedicated application optimization projects complementing the traditional HPC user support provided by NAG.
