I'm running Mathematica 8.0.4 on the latest, 2011 iMac (3.4 GHz Core i7, 16 GB RAM) under OS X Lion (10.7.3). The graphics adapter is an AMD Radeon HD 6970M (2048 MB VRAM). After loading OpneCLLink, OpenCLQ[] returns True. Yet evaluating examples from the ref page for OpenCLFractalRender3D returns nothing. E.g., OpenCLFractalRender3D[]. Moreover, it seems as if the OpenCL link is being closed, or the package unloaded, immediately after I try such an evaluation -- because if I evaluate it again, now I get the input expression itself returned; and indeed the $ContextPath no longer includes OpenCLLink (or the SymboliC and CCompilerDriver automatically added by loading OpenCLLink). What could be wrong? -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
