Siegmar,
I must admit I am having a hard time understanding why MPI.DOUBLE.getSize() returns 1 instead of 8 ... Anyway, for the time being, I think you can get the expected result by createResized(..., ..., 8). If there is a consensus that your program is correct, I will be happy to issue a PR (Simply multiply lb and extent by baseSize before passing them to the native function) Cheers, Gilles On Thursday, July 19, 2018, Siegmar Gross < siegmar.gr...@informatik.hs-fulda.de> wrote: > Hi, > > I've installed openmpi-3.1.0 on my "SUSE Linux Enterprise Server > 12.3 (x86_64)" with gcc-6.4.0.
