231.0. "MS VM bug on multi-processor system ?" by AIAG::KIM () Thu May 22 1997 12:02
I'm observing some bizarre behavior of my multi-threaded java program on my
dual cpu Prioris HX server. Basically, my program implements a simple
consumer-producer type of cooperative work between two threads for data
processing, and it works just fine on my single cpu Celebris box. But, when
I run it on dual cpu Prioris, the synchronization mechanism (ie, wait(),
notify(), etc.) seems to get lost, causing indefinite blocking, etc.
Has anyone experienced this ? I assume that all those (subtle) complexity of
dealing with multiple processors should be hidden below the operating
system, or at least by the Virtual Machine.
Any insight ? (BTW, I'm using Visual J++ VM)
