...n plot only the part that I wanted. The following example supposes simulates observations from a truncated normal with mean 0, standard deviation 1, and only observations above 1.5 are observed and we faked numbers between 1 and 1.5: set.seed(1) tst <- rnorm(1000) tst1 <- tst[tst>1] knl <- density(tst1) sel <- knl$x>1.5 plot(knl$x[sel], knl$y[sel], type="l") Are there any convenient methods for handling this kind of thing currently available in R? Thanks, Spencer Graves

Hi! When compiling the attached module with the JIT engine on an Intel KNL I see wrong code getting emitted. I attach a complete exploit program which shows the bug in LLVM 3.8. It loads and JIT compiles the module and prints the assembler. I stumbled on this since the result of an actual calculation was wrong. So, it's not only the text version of the assembler...

Hi all, We have a customer, where we are trying to install CentOS 7.3 on the new Intel Knights Landing nodes, unfortunately, we are unable to install then using PXE boot. Now, I have a lot of experience of installation of machines using PXE boot, so the setup of that is not the problem. Both myself and my colleagues have looked through the problem, and we are unable to get much diagnosis of
