The “production deployments” page on MongoDB’s site may be of interest to you. Lots of presentations listed with infrastructure information. For example: http://blog.wordnik.com/12-months-with-mongodb says they’re storing 3 TB per node.
You do something along these lines if( CMAKE_SIZEOF_VOID_P EQUAL 8 ) set( BOOST_LIBRARY “/boost/win64/lib” ) else( CMAKE_SIZEOF_VOID_P EQUAL 8 ) set( BOOST_LIBRARY “/boost/win32/lib” ) endif( CMAKE_SIZEOF_VOID_P EQUAL 8 ) set( CMAKE_EXE_LINKER_FLAGS ${BOOST_LIBRARY} )
Let’s try to answer this question by looking at people versus computers; hopefully this will shed some light on things for you: Things to Keep In Mind As amazing as they are, computers are very, very dumb. Memory People have memory (with the exception, arguably, of husbands and politicians.) People store information in their memory … Read more
There’s a great article on Wikipedia about the differences and benefits of 64bit Intel/AMD cpus over their 32 bit versions. It should have all the information you need. Some on the key differences are: 16 general purpose registers instead of 8 Additional SSE registers A no execute (NX) bit to prevent buffer overrun attacks
The JVM architecture in use can be retrieved using the “os.arch” property: System.getProperty(“os.arch”); The “os” part seems to be a bit of a misnomer, or perhaps the original designers did not expect JVMs to be running on architectures they weren’t written for. Return values seem to be inconsistent. The NetBeans Installer team are tackling the … Read more
This option is now part of Vs 2013 / 2015 / 2017: Tools | Options | Projects and Solutions | Web Projects | Use the 64 bit version of IIS Express
All calculations take place in the registers. When you’re adding (or subtracting, or whatever) variables together in your code, they get loaded from memory into the registers (if they’re not already there, but while you can declare an infinite number of variables, the number of registers is limited). So, having larger registers allows you to … Read more
x64 is used as a short term for the 64 bit extensions of the “classical” x86 architecture; almost any “normal” PC produced in the last years have a processor based on such architecture. AMD invented the AMD64 extensions; Intel was more or less forced to implement them, and called them first IA-32e, then EM64T and … Read more
The easiest way to check your workstation is to download the VMware Processor Check for 64-Bit Compatibility tool from the VMware website. You can’t run a 64-bit VM session on a 32-bit processor. However, you can run a 64-bit VM session if you have a 64-bit processor but have installed a 32-bit host OS and … Read more
As mentioned in the comments, starting with Ubuntu 18.04 and Linux Mint Tara you need to first sudo apt install qemu-kvm. To check the ownership of /dev/kvm use ls -al /dev/kvm The user was root, the group kvm. To check which users are in the kvm group, use grep kvm /etc/group This returned kvm:x:some_number: on … Read more
