在保加利亚超级计算中心的Bulgarian BlueGene/P和亚美尼亚国家网格计划（ArmGrid）的计算资源上进行了反胶束/油/水体系210 K原子的一系列基准测试。实验表明，随着处理机数目的增加，计算速度呈线性增长。应该注意的是，没有观察到饱和，最后我们使用4096个BlueGene/P处理器获得了0.121天/ns，同时ArmGrid基础设施中的数据显示了扩展的故障，这取决于处理器之间的通信时间。
Series of benchmarking of 210K atoms of inverse micelle/oil/water system have been carried out on Bulgarian BlueGene/P at Bulgarian Supercomputing Centre and on computational resources of Armenian National Grid Initiative (ArmGrid). The experiments show that the linear increase of speed of calculation with the increase of number of processors has been obtained. It should be noted that no saturation is observed and finally we received 0.121day/ns using 4096 processors of BlueGene/P, meanwhile the data within the ArmGrid infrastructures shows the breakdown in scaling, which is depends on communication time between processors.
