Hi Dongwook,

We identify a problem in ParA01 example which occasionally causes a seg. fault, depending on compiler and also the memory conditions. We believe the limitation you observed is not a limitation of Geant4MT itself, but due to a bug in ParA01. We will release geant4_mt_proto.9.5.p01 very soon, and this problem in ParA01 has been fixed.

Concerning about scaling, the test.in macro executes only 50 events. To observe scaling with large number of threads, you may want to increase the number of events.

Makoto
