Hi,
I am using r2 CVS with Linux 32-bit Intel g++ 3.4.1 as well as Linux
64-bit Opteron g++ 3.3.4 together with cheetah 1.1.4 & CVS and LAM 7.0.4.
I encounter crashes of r2/src/Particles/tests/bctest3 when running with
more than 10 contexts:
This is no wonder:
if (Pooma::context() == 0)
P.create(10,0,false);
P.sync(P.a1);
i.e. we create 10 particles - distributing over 11 contexts isn't going
to work. We don't handle contexts with zero particles gracefully. I
think there are similar problems with #patches < #contexts. But I'd
qualify these cases as user error.
Hope this helps,
Richard.
