It's in the code release directory again. I've made two changes: 1.At the end of calculate integrals there is: #ifdef GMLE_BOINC int retval = write_checkpoint(es); if (retval) { fprintf(stderr,"APP: astronomy checkpoint failed %d\n",retval); return retval; } #endif So in the rare case that this is the last checkpoint calculated (and there hasn't been a new one from the next integral calculation or likelihood calculation), the app will recalculate an integral which would give a bad result. The other change I did was move the code to checkpoint from the innermost integral loop, to the middle loop. This should speed things up a little (and maybe more than a little on older architectures). With the updates to 0.14 it seems like the bad results were quite a bit less frequent, so I'm hoping this was the last bit of the issue. |
