He gives an example of solving complex nonlinear systems [1] in a very few operations by using the inherent parallelism available via subdividing intervals.  He claims both accuracy and huge speed gains are possible.<p>[1] <a href="http:&#x2F;&#x2F;www.johngustafson.net&#x2F;presentations&#x2F;Multicore2016-JLG.pdf" rel="nofollow">http:&#x2F;&#x2F;www.johngustafson.net&#x2F;presentations&#x2F;Multicore2016-JLG...</a> (see example starting p.10)
