BP3 vs BP4 behavior changes.
Created by: NAThompson
Describe the bug
If we uncomment the bpIO.SetEngine("bp3")
line, the following program aborts with an exception:
adios2::ADIOS adios(adios2::DebugON);
adios2::IO bpIO = adios.DeclareIO("BPFile_N2N");
//bpIO.SetEngine("bp3");
adios2::Variable<Real> random_data = bpIO.DefineVariable<Real>("random_data", {}, {}, {v.size()}, adios2::ConstantDims);
std::string filename = "random_vector_" + std::to_string(state.range(0)) + ".bp";
adios2::Engine bpWriter = bpIO.Open(filename, adios2::Mode::Write);
bpWriter.Put<Real>(random_data, v.data());
bpWriter.Close();
adios2::Engine bpReader = bpIO.Open(filename, adios2::Mode::Read);
Desktop (please complete the following information):
