http://en.wikipedia.org/wiki/GeForce_400_Series says: "In the more expensive "Tesla" configurations, the chip features optional ECC protection on the memory, and can perform one double-precision floating- point operation per cycle per core; the consumer GeForce cards are artificially driver restricted to one DP operation per four cycles. " So, if I want double-precision float performance, what are my choices? _______________________________________________ PyCUDA mailing list PyCUDA@tiker.net http://lists.tiker.net/listinfo/pycuda
