Get the free pages information through virtio and filter out the free pages in the ram bulk stage. This can significantly reduce the total live migration time as well as network traffic.

...y other way to let Clang do so. What I am considering is how to let the generated IR looks like below, which some tools realize: define dso_local i32 @_Z1fPii([51 x i32]* %A, i32 %x) local_unnamed_addr #0 !dbg !7 { entry: ... } Best regards, ------------------------------------------ Tingyuan LIANG MPhil Student Department of Electronic and Computer Engineering The Hong Kong University of Science and Technology ________________________________ From: David Blaikie <dblaikie at gmail.com> Sent: Sunday, June 30, 2019 1:40 PM To: Tingyuan LIANG Cc: llvm-dev at lists.llvm.org Subject: Re: [l...

obviously, follow code is not working <p> <% if !@group.users.find(session[:user].id) %> <%= link_to "Join This Group", :action => "join", :id => @group %> <% end %> </p> "find" always throw an exception. I want to display the link of "find" fails, what is the right way to do this? Thanks. -- Posted via
