![]() ![]() Macintosh users may be tempted to use VMWare Fusion or Parallels with 64-bit Windows in order to run IGOR64. In this case you will need to devise a strategy for accessing your data in smaller sections. You may find that, even though you have enough virtual memory or even enough physical memory to hold all of your data at once, you have so much data that it is not practical to load it into memory. Sometimes this is not possible and you will have to live with the delays that come with swapping. Your best bet is to install enough physical memory that swapping is not necessary. Depending on your application, this may or may not create intolerable delays. If you load more data into Igor than you have physical memory, the operating system will have to swap data from physical memory to disk. Your actual maximum virtual memory is determined by the size of your virtual memory paging file, as explained in the next section. How much patience do you have while Igor loads, processes, graphs and saves very large amounts of data?.How much virtual memory swap space (on disk) do you have?.The limiting factors in practice then become: In practice, you are unlikely to hit this limit. So IGOR64 works in a virtual address space of 8 terabytes. In 64-bit Windows operating systems each process can address 8 terabytes (about 8000 GB - see MSDN). However, current 64-bit processor architectures and the Windows OS impose further limits. This is explained under Memory Management.Ī 64-bit address is capable of addressing 16 exabytes of memory, which is 16 billion GB or 16E18 bytes - see. IGOR32 works in a virtual address space of 2 GB, 3 GB or 4 GB depending on the operating system. When you see that IGOR64 is starting up you can release the control key. If you are running IGOR32 pre-6.20 and you want to run IGOR64 in a separate instance: If you are running IGOR32 6.20 or later, double-clicking either Igor.exe or Igor64.exe launches an instance of Igor even if another instance is already running. It is possible to run IGOR32 and IGOR64 at the same time. You may find it useful to create a shortcut for Igor64.exe and put the shortcut on your desktop. Therefore, if you want to run IGOR64, you must double-click the Igor64.exe file in your Igor Pro folder, not an Igor file. If you double-click an Igor file, Windows will launch and run IGOR32. That is, it is not listed in the Windows registry as being the application associated with Igor files. The IGOR64 application is not "officially" installed. The updater adds the following to your IGOR32 folder: Igor64.exeįolder containing 64-bit XOPs and other supporting filesįolder containing additional XOPs that you can activateīefore you run IGOR64, read the rest of this file to understand issues involved with IGOR64. Download the IGOR64 updater from here: setupIgor6-64.exe or here: setupIgor6-64.zipĭouble-click the setupIgor6-64.exe file to run the IGOR64 updater. The IGOR64 updater adds a 64-bit application and extensions into the IGOR32 folder. Download the latest IGOR32 installer from here: setupIgor6.exe or here: setupIgor6.zip You must install IGOR32 version 6.10 or later before updating to IGOR64. IGOR64 uses the same serial number and license activation key as IGOR32 6.0 and later. If you have an Igor Pro 6 license you are eligible to use IGOR64. Details are provided below under Virtual Memory Paging File. ![]() You should check the size of your virtual memory paging file. We recommend that you have at least 4 GB of physical memory. ![]() IGOR64 requires a 64-bit Windows operating system: Windows XP-64, Windows Vista-64, Windows 7-64, or Windows 8-64. IGOR64 does not run faster than IGOR32 on a 64-bit operating system. IGOR64 will afford you no benefits and is likely to have more bugs. If you are not dealing with gigabytes of data, you should stick with the standard 32-bit version of Igor. 5 GB each) or many smaller waves (e.g., 1000 waves of 4 MB each). This may be in the form of several very large waves (e.g., 16 waves of. IGOR64 will be of interest only to users who need to load gigabytes of data into Igor at one time. We are working on a 64-bit version for Macintosh as part of our Igor 7 project, which should be available this year. As of this writing (May 2016), IGOR64 for is available for Igor 6 on Windows only. This file describes the 64-bit version of Igor 6, known as IGOR64.
