Yes, it is important that it only happens with certan BLAS, so probably not really an R issue. However, there has been some concern over the C/Fortran interfaces lately, so if you could narrow it down to a specific BLAS routine, it could prove useful for the developers. One fairly easy thing to do would be to find the breakdown point. I speculate that it could be at 16384 (=2^14) and that some

Just updated from CVS 12-23-03 to tarbal 0.7.1. Identical settings in zconfig.h for echo cancellation (MARK2, aggressive OFF). The echo got worse, much worse. It takes longer to train and overspeak now disables cancellation, which it did not before. In fact, I now have echo on VoIP to VoIP on our local network, which I never had before. Was something changed with the echo supression which

I have the following code: ``` rm(list=ls()) N = 30000 xvar <- runif(N, -10, 10) e <- rnorm(N, mean=0, sd=1) yvar <- 1 + 2*xvar + e plot(xvar,yvar) lmMod <- lm(yvar~xvar) print(summary(lmMod)) domain <- seq(min(xvar), max(xvar))??? # define a vector of x values to feed into model lines(domain, predict(lmMod, newdata = data.frame(xvar=domain)))??? # add regression line, using

Note the difference: One side is trying to *help improve", while the other is *forcing to worsen*. This is really not helpful. --renato

Hello all, I'm new to the list, and hoping someone can point me in the right direction. I've got an Ubuntu 14 dom0 with, what I think, are excellent specs. 12 cores, hyperthreaded, VT, 64GB RAM, gobs of disk, etc... all to run 8 virtual machines (at the moment). My problem is each of the guests - Windows, Ubuntu, FreeBSD, starts out working fine. After several minutes, the guest

Hi, This patch improves compression a very tiny bit on average, but up to 0.1 percentage point for classical music.

Hi Jean-Marc > Can you explain what you mean here by "speech switching" By speech switching I mean the adaption of "gain2" when near-end or far-end is talking. What is important is that the timing is good and that the gain is low/high while far/near-end is talking. By timing I mean that the "gain2" should remain low until all far-end talk is final and that the

Which transformation passes are 'safe', meaning it does not worsens the effectiveness of a later pass or the generated code? I imagine all passes which either removes data or add attributes are included in this list, plus some simplification passes: -adce -argpromotion -constmerge -constprop -deadargelim -dse -functionattrs -globaldce -globalopt -gvn -instcombi...

I am using rsync to keep a mirror of my 800GB /home (server1). The backup machine is a separate server (servr2). Currently I am running rsync daemon on server2 and invoking rsync daily via cron on server2. Are there design / performance considerations that influence which machine is made the server and which the client? Also, Is the rsync daemon the preferred way to o this backup? I can also

Thank you for such a quick reply, here are some points that I think might have been missed: > I would state the question the other way : why are NAs integer indices allowed? > In my experience, they are sometimes useful but they often delay the detection of bugs. However, due to backward compatibility, this feature cannot be removed. Adding this feature to character indices would worsen the

This causes a signficant (10%+) performance hit. On

Again me. I want to plot the numbers on the bars of a barplot. This can be done using hist function when setting the label argument true (i.e. data <- c(1,2,3,4) hist(data, labels=T) When I try this using barplot I get an error: > barplot(summary(data), labels=T) Error in axis(if (horiz) 2 else 1, at = at.l, labels = names.arg, lty = axis.lty, : formal

Hello, Is it possible to alter how XCP enumerates multi-core cpu’s such that a Vcpu represents a “socket”, rather than a “core”? A server with dual quad core processors, no HT, presents each of the 8 cores as a Vcpu to the guest. Windows Server 2008 R2 see’s each Vcpu as a unique “socket” and we are therefore coming up against licensing issues with Windows and more importantly SQL Server 2008

According to the wiki at voip-info.org, the dial structure for using oh323 without a gatekeeper is: OH323/<exten>@<host>:<port> or OH323/<exten> The second option is valid only in the case where a gatekeeper is used. NOTE: OpenH323 library v1.12.0 has a bug in the parsing of the destination host. When this version is used then the above syntax should be:
