Closed rjtanner closed 10 months ago
After some more testing, this is an issue with my data(-ish). In my data there are a few cells that just produce a huge number of photons (high density, high temperature, and/or high velocities). The excessive number of photons generated from a single cell causes memory issues because of the way prng.uniform and .sort() work. I applied a filter to my data to remove these extreme point sources and now it works.
@rjtanner can we close this or should we address it somehow?
I am using version 4.1.1
Inside the for loop starting at line 357 in thermal_sources.py, my simulations are failing at lines 402-404 (I don't know which line). It happens when cn is large, > 10000000. When it fails, Python does not throw an exception or produce an error. The process is simply killed. It is possible it is a memory error because cn is so large the arrays generated should be massive.
Relevant lines where the code fails:
402 randvec = self.prng.uniform(size=cn)
403 randvec.sort()
404 cell_e = np.interp(randvec, cp[icell, :], self.bin_edges)
