Hey All,

I just wanted to let you know that we will be releasing a version of Nbody tomorrow. I will be more specific on the changes that have been made after releasing. However, this version should hopefully be much faster and fix some other bugs.

This latest nbody is not using multiple CPUs as expected. It tells BOINC it's using 7 CPUs, but Windows task manager clearly shows it using only one CPU.

Same issue here ... It is using ONE CPU, (says 4) but also seems to be prohibiting work on the others. The WU has been running for well over 8 hours, even though the progress is showing 100%. May end up aborting this unit.

I deleted one that ran for nearly 8 hours.

I've only had one of the new N-Body WUs complete

The rest reach 100% adn the keep "running" forever, until I abort them

I've also seen the behavior described in another thread. BOINC Manager shows N-Body using 12 CPUs (multi-threading), but Task Manger shows only one processor in use

At the same time BOINC Manager won't let any other WUs run because all teh CPUs are:"in use"

I have, as a result, stopped accepting N-Body WUs
