Ah, hadn't tried turing off cpuspeed. Try again... nope same error. 2 cpus, each: model name : Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz stepping : 11 cpu MHz : 800.000 << that's what it says @idle cache size : 4096 KB _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
