Support of multiple core 64 bit processors and 4GB RAM
Just wondering if there is image processing software which can make full
use of 64 bit processors with more than one core (i.e. Core 2 Duo, Core 2 Quad or equivalents from AMD) and which can use more than 4GB RAM (I know for instance of mainboards which take 8GB RAM)? Intel is planning to have a processor with 32 cores by 2009. -- Alfred Molon ------------------------------ Olympus 50X0, 7070, 8080, E300, E330, E400 and E500 forum at http://tech.groups.yahoo.com/group/MyOlympus/ Olympus E330 resource - http://myolympus.org/E330/ |

Support of multiple core 64 bit processors and 4GB RAM
The OS is the limit.
32bit Windows does not see all the 4gb of RAM. Although 64bit Windows technically can see all that RAM it has problems with stability, program and driver compatibility. Win64 will run Photoshop but many if not most users cannot use that much RAM effectively. Vista64 will not be any different, at least at outset, than Win64 and probably have even less driver support for things like printers, scanners and calibrators. In fact there will be inadequate driver support when Vista 32 is released in a few weeks. The truth is that users may think they need that much RAM but the reality is somewhat different despite what some computer enthusiast magazines/web sites tout. |

You'd need large amounts of RAM when processing large image files, for instance scans of MF or LF negatives or pnoramic stitches. -- Alfred Molon ------------------------------ Olympus 50X0, 7070, 8080, E300, E330, E400 and E500 forum at http://tech.groups.yahoo.com/group/MyOlympus/ Olympus E330 resource - http://myolympus.org/E330/ |

Intel is planning to have a processor with 32 cores by 2009. I believe that Adobe PhotoShop uses the facilities of the 64 bit processors. Whether or not a program uses the dual core machines to full advantage depends on both the architecture of the program, and the setting, and design, of the compiler. Using multiple processors is not a simple thing, and even if the program is compiled for optimal multi-processor use, the OS must also support it well in order for maximum benefit to be derived. For any given program design, there is a point of diminishing returns when it comes to adding processors. At some point, no further advantage in speed will be noted. The RAM issue depends on board design, and OS limitations. |

Windows XP, for example is 32 bit and can read 4GB of ram in which 2GB is given to the OS and 2GB is given to the apps. There is a startup switch to give 1GB to the OS and 3GB to the apps, however the max RAM per app (per session) is still limited to 2GB. The 64 bit versions, of course, are not limited this way, but you need a 64 bit app (like you asked about). I'm not sure if PS is truly 64 bit. You must have a lot of images open or do a lot of stitching of many smaller files to need such a large amount of RAM. Don't know about 32 cores! Quad cores are just getting started and they will likely run for the next couple years. 32 cores may be used for mini and super computing uses. I don't see it in the desktop market for many more years. -S |

Actually image processing is one task which can easily be parallelised - just split the image into parts and assign each part to one processor. Or, if you are doing panoramics, assign one image of the set to each processor. -- Alfred Molon ------------------------------ Olympus 50X0, 7070, 8080, E300, E330, E400 and E500 forum at http://tech.groups.yahoo.com/group/MyOlympus/ Olympus E330 resource - http://myolympus.org/E330/ |

You must have a lot of images open or do a lot of stitching of many smaller files to need such a large amount of RAM. The problem is that with typical panoramas even 2GB are sometimes not enough, and the computer starts disk swapping. For instance, with PTGUI a panorama with the layered output option with ten 10MP images generates easily a 300MByte file. Open that in your image processing software, with multiple undo levels and you quickly end up filling up several GB of RAM -- Alfred Molon ------------------------------ Olympus 50X0, 7070, 8080, E300, E330, E400 and E500 forum at http://tech.groups.yahoo.com/group/MyOlympus/ Olympus E330 resource - http://myolympus.org/E330/ |

Sorry, but isn't an advantage of 64 bit processors, that they can address more than 4GB of RAM, which should help with memory hungry situations? As for multiple cores, they should help with image processing, an application which can easily be parallelised. -- Alfred Molon ------------------------------ Olympus 50X0, 7070, 8080, E300, E330, E400 and E500 forum at http://tech.groups.yahoo.com/group/MyOlympus/ Olympus E330 resource - http://myolympus.org/E330/ |
