I've got problem that I thought would scale well across cores. def f(t): return t[0]-d[ t[1] ]
d= {k: np.array(k) for k in entries_16k } e = np.array() pool.map(f, [(e, k) for k in d] At the heart of it is a list of ~16k numpy arrays (32 3D points) which are stored in a single dict. Using pool.map() I pass the single item of 32 3D Points to be evaluated again the 16k entries. In theory, this would be a speedup proportional to the number of physical cores, but I see all 4 cores being maxed out and results in a regular map time. How can I use pool.map better? -- https://mail.python.org/mailman/listinfo/python-list
