Hi. Installed PyCUDA 0.94.1 in several Linux boxes. All have Ubuntu 10.4 with CUDA 3.1 (drv 256.40) and python 2.6.5
Boxes with 1.1 capability GPUs like 8600GT, 9400 GT or FX850 are ok and some user's are already trying them. Boxes with 1.3 (GTX280) and 2.0 (GTX480) have dificulties just running the supplied tests. On these: test_cumath.py passes all tests but is 5 times slower in the GTX280 and 40(!) times slower in the GTX480 As far as I can see, this test never uses float64 test_driver.py passes all tests but is 4 times slower in the GTX280 and 9(!) times slower in the GTX480 As far as I can see, this test also doesn't use native float64. Testing fp_textures seem to be done with some sort of emulation, but I may be wrong here. test_gpuarray.py is 2 times slower in the GTX280 and fails the dot, sum, minmax and subset_minmax tests on the GTX480. Can anybody please point me to some mail thread, FAQ or instalation guide that helps me correct whatever I have done wrong?
