Is it possible to run Mathematica on an HPC cluster with Torque? Just for curiosity's sake, can you tell s bit about what you want to do with all of this, what problem you want to solve or model or calculate? |

Simulating a Stochastic Process within certain bounds No time to try this, but I wonder if Rescale or RescalingTransform might help? |

What technical obstacles prevent all Mathematica code compiling to C I don't know why a specific compilation needs to compile the entire kernel. By all accounts,WRI has highly modularized the kernel. It would seem the "kernel" includes a wide range of components that C or other languages view as libraries. What I want, wouldn't need to compile all of these anymore than one needs to distribute every existing C library with every application. I don't suggest WRI or anyone could do this easily or that it wouldn't require restructuring the kernel's code. Also, for me I have more concern with distribution of stand alone applications & components than efficiency. |

Standard Deviation and StandardDeviationFilter You seem on the right track. Not certain how one gets to it from the documentation. Curious, with your code: Most[Rest[sd1]] == Most[Rest[sd2]] returns True, sd1==sd2 doesn't. |

What technical obstacles prevent all Mathematica code compiling to C @Szabolcs -- Agreed, but pushing the various players seems more a "business" strategy rather than not doing something because of the difficulty. They seem to fear that it will hurt their franchise if applications built in Mathematica don't have to run on some WRI platform. |

What technical obstacles prevent all Mathematica code compiling to C @Stefan -- I found the most interesting thing about .NET when it appeared was that it allowed a programmer to use almost any language, but it essentially all compiled down to the same code. Much more complicated with Mathematica and all its extensions, but gee, why not? |

What technical obstacles prevent all Mathematica code compiling to C @Szabolcs -- Despite a keen interest in things like parallel processing, over the past few years, my work has moved more to finding analytic solutions (geometric, matrix, decompositions). One can't do this with everything (or at least I haven't figured out how to do so), but in their specific applications these approaches run very fast so I have less of a need for brute speed than in the past. My main interest now revolves around deployment (we've had some of these conversations before). Still, wouldn't compiled code get you both? |

Access curated or locally stored data with curated data functions? @LeonidShifrin -- You have a generous spirit. Nice to have you in the world. |

Access curated or locally stored data with curated data functions? @LeonidShifrin -- Certainly worthy of an accepted answer in my opinion. If you want to post it, you've got my vote. - Thx. |

Access curated or locally stored data with curated data functions? @LeonidShifrin -- I think I understand. The r.h.s would become my Import[pathAndFileName]. That should enable me to do additional statements for other symbols that would correspond to their own data sets? |

How do I remove this awkward plane? Ahhhhg, just saw the comments. Happy to withdraw my answer if one of you wants to supplant it. |

Plotting data points: Optimizing size and visuals I think about this kind of data compression problem a lot. It forces one to ask some interesting questions. What features of the data do you want to preserve? What features of the data don't matter? What features only describe noise? What features of the data to you regard as actual information? If you just want the data's general trend a moving average will do as @kale suggests, but a moving average will clip your extrema. If you want to capture extrema, than an iterative compression algorithm might make the most sense. Give it some thought, let us know. I may have something for you. |

Problem with PlayerPro recognizing a proprietary package Yes, got everything running except the init.m stuff. I hope to hear something back from Premier Support on this. They have escalated the issue to the development group. I'll report back if i get anything. And many thanks for the thoughtful and thought provoking answer. |

Problem with PlayerPro recognizing a proprietary package As I mentioned in a comment to another answer, after going through all of your suggestions, the init.m file whether encoded or not simply doesn't do its job. Note: I use PlayerPro 9.0.1.0. I'll amend my original question to warn others. Does such an init.m package work for you in an earlier version? One can work around this certainly, but I'd like to understand why it doesn't work. Waiting to hear from Wolfram ;-( |

Problem with PlayerPro recognizing a proprietary package Thanks for this suggestion. It actually (after much fiddling around and testing) works. This provides a workaround to the problem of init.m (Encoded or not), simply not calling a package in the Applications directory. The init.m file not working seems like a bug. If not a bug then one would hope that Wolfram (in documentation or via Premier Support) would provide a reason for why this differs from Mathematica, neither has provided such. +1 |

Problem with PlayerPro recognizing a proprietary package @AlbertRetey -- The default init.m package (even though it doesn't have actionable code) that PlayerPro creates if one doesn't exist in the Kernel directory does not appear encoded. This default file has a comment saying (** User Mathematica initialization file **). One would think that this would indicate that an init.m package with a Get statement ought to work in this directory. |

Problem with PlayerPro recognizing a proprietary package @AlbertRetey -- I was just planning to update my question to state that yes, all along I have used Encode on the package in question. |
