This model runs on an XP machine with 4 GB RAM, whereas the new Windows 7 machine has 32 GB (paging file is 16x that of the XP machine), so available memory can’t exactly be the problem. Is there a difference in the latest ADMB that accounts for this? Does the move from a 32-bit to 64-bit machine confound something? I notice that the System-Performance Options-Advanced has changed between OS’s. Both allow Processor scheduling and Virtual memory adjustments, but only XP has a separate Memory usage (Programs vs System cache). On both machines I opt for Programs, but don’t know how the Windows 7 machine resolves the absent Memory usage block. The no-longer-working program was a Borland compile with the following memory settings:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> arrmblsize=90000000;<o:p></o:p></p><p class=MsoNormal> gradient_structure::set_GRADSTACK_BUFFER_SIZE(2500000);<o:p></o:p></p><p class=MsoNormal>gradient_structure::set_CMPDIF_BUFFER_SIZE(200000000);<o:p></o:p></p><p class=MsoNormal> gradient_structure::set_MAX_NVAR_OFFSET(2500);<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I also compiled a mingw version on the new system with the latest ADMB (problems reported in earlier email were due to incompatible Borland include files – resolved), and get the same response, immediate memory allocation error with no churning.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Anyone know why it no longer obtains the needed memory?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-US style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D;mso-fareast-language:EN-CA'>Mark Fowler</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D;mso-fareast-language:EN-CA'> <br></span><span lang=EN-US style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D;mso-fareast-language:EN-CA'>Population Ecology Division</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D;mso-fareast-language:EN-CA'> <br></span><span lang=EN-US style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D;mso-fareast-language:EN-CA'>Bedford Inst of Oceanography</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D;mso-fareast-language:EN-CA'> <br></span><span lang=EN-US style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D;mso-fareast-language:EN-CA'>Dept Fisheries & Oceans</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D;mso-fareast-language:EN-CA'> <br></span><span lang=EN-US style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D;mso-fareast-language:EN-CA'>Dartmouth NS Canada</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D;mso-fareast-language:EN-CA'> <br></span><span lang=EN-US style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D;mso-fareast-language:EN-CA'>B2Y 4A2</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#1F497D;mso-fareast-language:EN-CA'> <br></span><span lang=EN-US style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D;mso-fareast-language:EN-CA'>Tel.
