Here are the results, comparing a VMWare virtual machine against the same operating We made the waves, assigned the number 1 to them,Īnd killed the waves. Merely big unsigned byte waves (2,097,152 points each). We did three tests - a hugeĭouble-precision wave (536,871,012 points), a huge unsigned byte wave (8,589,934,592 points) and 1000 We tested with 5 GB allocated to the virtual machine. Allocating the 7 GB to the virtual machine made the entire machine, both Windows and Just the default 2 GB allocated to the virtual machine, memory swapping made Igor run very slowly for The amount of RAM allocated to the virtual machine makes a big difference. We did some very simple testing using Windows Vista 64 running under VMWare Fusion on a Mac Pro with 8 GB of memory. Macintosh users may be tempted to use VMWare Fusion or Parallels with 64-bit Windows In this case you will need to devise a strategy for accessing your data in smaller sections. Memory to hold all of your data at once, you have so much data that it is not practical to load it into You may find that, even though you have enough virtual memory or even enough physical 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 Will have to swap data from physical memory to disk. If you load more data into Igor than you have physical memory, the operating system Paging file, as explained in the next section. Your actual maximum virtual memory is determined by the size of your virtual memory
