64-bit

问题 Hello and thanks in advance. I'm using Rx64 version 3.1.2 on a Windows Server and have a file-backed big matrix generated from the package bigmemory that I'm trying to use in a linear programming problem. The matrix is 7062 rows by 364520 columns for a total of 2574240240 entries (of integers). When I run the line for the linear program, I get the following error: Error in GetElements.bm(x, i, j) : Too many indices (>2^31-1) for extraction. That number, 2147483647, from what I read is the

问题 I have 32 bit .net application solution project. It uses many third party dlls (32 bit). This app runs on both 32 bit and 64 bit (as a 32 bit process, compatibility mode) platform. It uses 32 bit DLLs even if it is running on 64 bit platform. I need to rebuild this application in order to let it use/load 32 bit Dll on 32 bit OS and use/load 64 bit DLLs on 64 bit OS. As existing 32 bit app runs on 64 bit systems in compatibility mode but I want it to be run as a dedicated 64 bit app on 64 bit

问题 I recently upgraded to a 64-bit machine, (I know I'm behind but everything was running and I'm cheap). I use XAMPP on my older machines to stand up local web dev and want to do the same on my new machine. However I'm having significant trouble getting XAMPP or WAMP to run properly under the 64-bit install. WAMP simply won't install saying that the setup files are corrupted and XAMPP installs but throws an error about running from the XAMPP directory on control panel launch and Apache will not

问题 it seems IIS6 on Win2003 R2 Enterprise x64 SP2 will not allow you to use .com in a url path. e.g if i create a folder foo.com in my web root, containing a default.htm, this url results in a 404: http://localhost/foo.com/default.htm however, following the exact same steps on Win2003 R2 Standard x86 SP2, and IIS6 will serve up the file just fine. Neither server has urlscan installed. Is there a way to tell IIS6 on Win2003 x64 to allow .com in a url path? 回答1: This looks like it might relate the

问题 during the analysis of a memory dump for a .Net4.5 WCF w3wp process, I encountered many threads identified as dead. !threads shows 68 out of 107 threads are dead which appear to be quite high. I was wondering if these threads could hold large amount of memory since the process eventually goes as high as 20GB+ and seem to never go down. How can I inspect such threads and see the objects/memory held by these? Is it normal to have so many? 0:000> !threads ThreadCount: 107 UnstartedThread: 0
