...I tried using ATLAS with sse2. I'm pretty sure it's valid assembly; the code still causes exceptions when i try using the output from the llvm demo website. And it works fine on an AMD machine. What is LLVM doing with my code ? Does it generate SSE2 instructions ? thanks!

Dear All, I cannot find a solution to the following problem although I imagine that it is a classic, hence my email. I have a vector V of X values comprised between 1 and N. I would like to get random samples of X values also comprised between 1 and N, but the important point is: * I would like to keep the same distribution of distances between the X values * For example let's say N=10 and

Hi Simon, The x86 backend does generate scalar SSE2 instructions. For your example, it should emit something like: .text .align 4 .globl _sum_d _sum_d: subl $12, %esp movl 20(%esp), %eax movl 16(%esp), %ecx cmpl $0, %eax jne LBB_sum_d_2 # cond_true.preheader LBB_sum_d_1: # entry.bb9_crit_edge pxor %xmm0, %xmm0 jmp LBB_sum_d_5 # bb9 LBB_sum_d_2: # cond_true.preheader...

Hello Everyone, My name is Thomas and I have been using R for one week. I recently found your site and have been able to search the archives of posts. This has given me some great information that has allowed me to craft an initial design to an inquiry I would like to make into the breakdown of McNemar's test. I have read an intro to R manual and the posting guides and hope I am not violating
