I just tried it in serial on Stephen's data and it worked. I'll queue it up for the larger data. I intend to try a few different processor configurations to get some information on the ram usage.<br><br>Britton<br>

Guys,<br>
<br>
What seems to be happening was a floating point comparison issue. It<br>
must just be something with the way the particles were aligned in the<br>
new dataset compared to the old. Changing the type of 'fm' on line 59<br>
of hop_kd.c from 'float' to 'npy_float64' fixed it for me; the loop<br>
was never converging as a result, so it ran off the end and segfaulted<br>
when it was unable to locate any more data points insie the process's<br>
memory. There may be other places that this needs to happen, and I<br>
will look for them, but if you could test with this change that'd be<br>
awesome.<br>
<br>
Let me know if that fixes it? And if the memory improves?<br>
<br>
