I am literally running out of resources where to ask for this, since nobody seems to be interested about it, nor anybody seems to actually get the issue, but I am wondering, what factors may interplay in the scalability being affected when executing the pdgbdriver.f for banded matrices, that comes in the ScaLAPACK distribution?I have tried many different options but scalability seems to baffle me
Thanks in advanced and kindest regards.
PS: I tried to post this in a prior thread about performance, and my message got declined because of being "spam".
