For instance, is it threaded? How was it built? Compiler used, libraries called, system routines accessed? What kinds of computation does it do (without user intervention)?What processors have you run this on?</P> <P>-- clay</P> <DIV></DIV> Fri, 16 Apr 2004 03:42:05 GMT https://community.intel.com/t5/Intel-Moderncode-for-Parallel/XP-KRNL386-EXE-crashed-under-Hyper-Threading/m-p/963600#M5370 ClayB 2004-04-16T03:42:05Z https://community.intel.com/t5/Intel-Moderncode-for-Parallel/XP-KRNL386-EXE-crashed-under-Hyper-Threading/m-p/963601#M5371 <DIV><STRONG>Can you provide more details on your application?</STRONG></DIV> <DIV><STRONG></STRONG></DIV> <DIV>Yes, of course.</DIV> <DIV><STRONG></STRONG></DIV> <DIV><STRONG>For instance, is it threaded?</STRONG></DIV> <DIV><STRONG></STRONG></DIV> <DIV>No, it's 16-bit app for Windows. So, it can't be multithreaded....</DIV> <DIV>It works in one timer procedure.</DIV> <DIV><STRONG></STRONG></DIV> <DIV><STRONG>How was it built? Compiler used, libraries called, system routines accessed?</STRONG></DIV> <DIV><STRONG></STRONG></DIV> <DIV>My app build under Borland C++ 4.5 (very old project, but i must maintain it). It works with our own drivers (own soundcards)and also use 16-bit to 32-bit thunk mechanism.</DIV> <DIV><STRONG></STRONG></DIV> <DIV><STRONG>What kinds of computation does it do (without user intervention)?</STRONG></DIV> <DIV><STRONG></STRONG></DIV> <DIV>Basically, appgets sound stream (telephone talks) from our sound cards, processing it (some sound filters) and store to own DB.</DIV> <DIV><STRONG></STRONG></DIV> <DIV><STRONG>What processors have you run this on?</STRONG></DIV> <DIV><STRONG></STRONG></DIV> <DIV>For example, on</DIV> <DIV><FONT size="2">Intel Pentium 4HT, 2800 MHz (3.5 x 800) Northwood HyperThreading </FONT></DIV> <DIV>CPU params: <FONT size="2">x86 Family 15 Model 2 Stepping 9 GenuineIntel ~2806 ??? </FONT></DIV> Tue, 20 Apr 2004 17:25:58 GMT https://community.intel.com/t5/Intel-Moderncode-for-Parallel/XP-KRNL386-EXE-crashed-under-Hyper-Threading/m-p/963601#M5371 rybakov_anton 2004-04-20T17:25:58Z
