Hi,
We are using the Stata wrapper of osrm to find routes for millions of observations. I have finally deduced that one thread does not work when the number of observations is large enough. 5 million is large enough; 1 million is not. The return code is 3=Something else is wrong for exactly 25% of the observations when I specify 4 threads (or allow it to default); 12.5% of the observations when I specify 8 threads. I have four cores with 2 threads each. (I am testing two threads now). I suspect it is the first thread that has a problem, since it is the first observations that do not solve. Does anyone know what is going on or how to fix this? It almost sounds like the first thread has some other responsibilities that cause problems when there are too many records. But could it be a hardware problem? Thanks! Bryan Sayer Statistician, SSS, Inc. www.s-3.com ****WARNING**** This information may be confidential.
