Hello, Writing to seek help in regard to some unexpected performance anomaly i am observing in using tsoutlers:tso on the mac vs on an AWS cloud server.. I am running the following code with very small dataset of about 208 records. d.dir <- '/Users/darshanpandya/xxxxxx' FNAME <- 'my_data.csv' d.input <- fread(file.path(paste0(d.dir,"/zzz/"),FNAME,fsep =

I have question about multipath routing. I am running a 2.6.7 kernel (gentoo). I have a route with three nexthops on the same interface. I see a different nexthop being picked for different destination addresses. All is fine. Now if one of the nexthop goes down (arp entry times out and arp request doesnt get a response), does it remove the nexthop from contention and only use the remaining two

Sorry, I pasted the wrong file in earlier... this is the correct one: pValCalculator(b, n=20, m=20) { ind <- 1:min(c(n,m)) prob <- (1-pnorm(b,sd=std*sqrt(ind))) prob1 <- sum((n-ind+1)*(m-ind+1)*prob) prob1 } inputData <- scan("/users/lvssso/projects/LAMA/output/pValLamaScore.tmp", list(block1 = "",block2 = "",width1 = 0,width2 = 0,alignment = 0,score

Hi, I have a simple question that I just cannot figure out. I have 2 corresponding columns of data, one column (X-axis) for time (formatted thus: 8:30:01am = 830.1, 12:30:05pm = 1230.5, and one column (Y-axis) for values. When I attempt to plot the data using something like plot(inputdata[,1],inputdata[,2],type="l"); I get breaks in the plot (since the time essentially jumps from

Hi all, I have a question regarding the memory usage for the attach function. Say I have a data.frame inputdat that I create with read.csv. I would like to know what happens on the memory side when I use attach(inputdata) Is there a second allocation of memory for inputdata? Then I'm using eval on a expression which depends on the columns of inputdata. Is it better not to use attach

Hello, I have created a .dll file using G77 and MinGW on my PC (Windows 2000). After using dyn.load to bring it into R2.0.1, I then call the .dll through the function ccprox shown below. It returns the correct values. If I run it a second time though it returns different values, so it seems something is being placed oddly in memory. If I unload and reload the .dll it works again the first

Seems like an oversight that we have set-tx-csum and set-sg hooked up, but not set-tso. Also leads to the strange situation that if you e.g. disable tx-csum, then tso doesn't get disabled.

Hi, What's the correct way to disble TSO (TCP Segmentation Offload) in RHEL5? I have tried adding those options in ifcfg-ethX configuration file: # grep ETHTOOL /etc/sysconfig/network-scripts/ifcfg-eth0 ETHTOOL_OPTS="tso off" And also with: ETHTOOL_OPTS="-K eth0 tso off" But when restating the server TSO is enabled: # ethtool -k eth0 tcp segmentation offload: on As

We've been encountering an issue in the virtio-net driver that cause it to become unresponsive after a period of high load. This issue goes away if we disable TSO on the interface. Once this issue has been triggered, the interface can still receive traffic, but will not transmit anything. Specifically: * Initially the machine will still try to respond to packets (I say try, because I

I am trying to turn ON TSO in my Ubuntu Virtual machine but it gives me the following error: [image: image.png] Also on doing *ethtool -k ens3* all the features are marked as [fixed]. How to use libvirt to configure VM to have TSO?

Hi, Sorry to bother you guys with this syntax problem, this is my first R program, and I seem to not have grasped something right. I keep getting an error message from 'parse' on the line with the *** : pValCalculator(b, n=20, m=20) { ind <- 1:min(c(n,m)) prob <- (1-pnorm(b,sd=std*sqrt(ind))) prob1 <- sum((n-ind+1)*(m-ind+1)*prob) prob1 } inputData <-

Hi, I see you all agree to apply :) Stephen, repost of this patch to proper places below. Thank you Henrik for clarification of bridge standard. However, silent drop of locally generated packets on 99% idle carrier grade machine looks like a hardware problem. David, don't you think that having software packet drop counters is a bad idea? I thought, software drop counters are there to help

Since virtio does not provide it's own ndo_features_check handler, TSO, and now checksum offload, are disabled for stacked vlans. Re-enable the support and let the host take care of it. This restores/improves Guest-to-Guest performance over Q-in-Q vlans. CC: "Michael S. Tsirkin" <mst at redhat.com> CC: Jason Wang <jasowang at redhat.com> CC: virtualization at

Greetings R-help! I'm fairly new to R and am trying to expand my knowledge beyond using R for simple summary statistics and basic tests. To that end I am attempting to write an interactive R-script that will perform a general rational function fit to a given dataset based on the example given at http://www.itl.nist.gov/div898/handbook/pmd/section6/pmd64.htm. The problem that I seem to have

Hi Keir: [LINUX] netfront: Cleanup and fix TSO/GSO/CHECKSUM conditionals This patch tries to minimise the amount of code that is conditionally compiled. This is desirable (and the Linux way) as it helps to prevent people breaking code unwittingly since conditionals may hide compile problems. It also adds a missing conditional around the TSO ethtool operations. This also helps the building of

Hi everybody, I a, trying to use R as a pipe like this: cat inputData | R --silent RCommandFile >outputData The RCommandFile would contain something like readLines(stdin()). I have tryed various things and none did work cleanly. One possible solution is to use the pipe() function inside R and to pass in the "cat inputData" however this is not very convenient since I would like to

Hello everyone, Hopefully a simple question. How can I access function argument alignment information? If my code has something like this: void foo(short * __restrict __attribute__ ((aligned(8))) InputData){} ...as I deal with argument (InputData) can I get the alignment info set for it? Thanks!
