Hmm, on my computer, I get around 2.5 seconds with both gcc -O3 and llvm-gcc -O3 (using llvm-gcc from svn). Not sure what you're doing differently; I wouldn't be surprised if

You might want to try reading the LLVM IR (which you can > generate with llvm-gcc -S -emit-llvm); it tends to be easier to read. I tried that, but I'm still learning LLVM.

Dear All I'm making a transformation pass that inserts a new basic block at the start of a loop. However when I try to change predecessor/successor relations, it does not consider the new block in the loop at all. So I got that just inserting a loop in a function before another loop is not enough. So how exactly to do this job? Regards, Marwa Yusuf Teaching Assistant - Computer Engineering

Do you have any idea of the sort of timescale, and whether it'll be available as a patch that we can apply to our

Hi - I saw your posting on the R-help mailing list. Were you ever able to get this working? did you end up switching to use the rsge library? I'm trying to do the same, and not having very much luck getting it going. Thanks! Peter Waltman [[alternative HTML version deleted]]

How do I specify a "tight" y-axis, where the plot completely fills the y-axis range, inside the prepanel function? For example, consider the following code: require(lattice) set.seed(12345) x <- 1:1000 y <- cumsum(rnorm(length(x))) prepanel.test <- function(x, y, groups = NULL, subscripts = NULL, ...) { if (is.null(groups)) { result <- list(ylim = range(y)) }

Hi, What if some fail2ban magic could keep OpenSIPs response from hitting Asterisk after N attempts ?

Any tips or guidance on improving the probability of being able to connect to a Tinc daemon. I am currently on a guest wifi at a hospital for my in-laws family. Wanting to pass time and be semi productive, I tried to VPN back to my private networks but it appears the default port Tinc users is blocked. Here is what I know about their firewall:

We have spent some time setting up Sun Grid Engine and OpenMPI on a group of linux boxes. I have created a parallel environment and everything seems to be working. I have Rmpi 0.5.5-5 installed on all machines. I would like to start an interactive R session using, say, 8 processors and then start the Rmpi cluster. I haven't been able to find what needs to be done in order to accomplish

We've been using rsync since forever to back up all our servers and it's worked without a problem. But in a recent security review, we noted that our specific rsync backup host is using root keys to access the server, meaning that if the keys on the backup server were leaked/compromised in any fashion, that would provide r00t access to the servers being backed up. Since this
