I am running cygwin on a 64-bit Dell XPS, running Windows 7, with a Core i5 processor, and 12 GB of RAM installed. The fortran 90 code I am running keeps running out of memory (virtual memory or stack overflow errors) on jobs that the computer should easily handle. I have increased the paging memory to 36 MB, but I am afraid that CygWin is still being limited to ~ 1 GB of memory. My problem is very similar to what is described here: http://cygwin.com/ml/cygwin/2011-01/msg00196.html I followed the instructions at [1] and [2] to increase the heap chunk available to cygwin, but I have also read that adding a /largeaddressaware link might further increase the amount of memory available to cygwin (see [3], which confused me a lot). I have not been able to find clear instructions about how to do this for cygwin, could you help? Also, I am interested in any tips about how to maximize the amount of memory available to cygwin given my 64-bit windows 7 setup! Thanks very much for your kind help to a very helpless geologist!
