similar to: [PATCH] Btrfs: optimize reada_for_balance

The following has been done as a part of cleanup - o Eliminated bin_search() by replacing with btrfs_bin_search() o Eliminated unused return value in fixup_low_keys() o Eliminated additional variable (sret) in setup_nodes_for_search() Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.de> --- ctree.c | 71 ++++++++++++++++++---------------------------------------------- 1 file changed, 20

This patch introduce extent buffer cache for every i-node. By this way, we can save the search time and reduce the lock contention of the root because we needn''t search the item from the root of b+ tree. Implementation: - add two pointers of extent buffer into btrfs_inode struct, one for nodes/leaves of fs/file tree, the other for nodes/leaves of the log tree. - add a variant to tell

Lets say you had 4 servers and you wanted to setup replicate and distribute. What methoid would be better: server sdb1 xen0 brick0 xen1 mirror0 xen2 brick1 xen3 mirror1 replicate block0 - brick0 mirror0 replicate block1 - brick1 mirror1 distribute unify - block0 block1 or server sdb1 sdb2 xen0 brick0 mirror3 xen1 brick1 mirror0 xen2 brick2 mirror1 xen3 brick3 mirror2 replicate block0 -

Dear all, I want to compute the average of the three blocks for each x-variable which is equal slide in the code below. How can I do that ? block x1 x2 x3 x4 x5 1 23 22 23 24 23 1 21 25 26 21 39 1 23 24 22 23 23 2 20 21 23 24 28 2 32 23 34 24 26 2 19

Dear Madame, Dear Sir, I am able to obtain the coefficients from a 'summary' of 'lm', but NOT from a 'summary' of 'aov'. The following example shows my steps. ## Initialize rm(list = ls()) # remove (almost) everything in the working environment utils::data(npk, package="MASS") # get data model <- yield ~ block + N*P*K ## Using lm npk.lm <-

Dear R helpers, I have what another member on this forum described as an embarrassingly parallel problem. I am trying to fit models on subsets of some data based on unique combinations of two id factors in the dataset. Total number of combinations is 30^5, and this takes a long time. So, I would like fit models for each of the datasets produced by subsetting on the unique combinations, splitting

I would appreciate it if someone could explain the results of the example from the aov() help file. The output given below is different from book Venables and Ripley - MASS The results In R1.5.1 (Under windows) is as follows: > N <- c(0,1,0,1,1,1,0,0,0,1,1,0,1,1,0,0,1,0,1,0,1,1,0,0) > P <- c(1,1,0,0,0,1,0,1,1,1,0,0,0,1,0,1,1,0,0,1,0,1,1,0) > K <-

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 am running a large number of jobs (thousands) in parallel (linux OS 64bit), R version 2.14.1 (2011-12-22), Platform: x86_64-redhat-linux-gnu (64-bit). Up to yesterday everything ran fine with jobs in several blocks (block1, block2 etc) of submission. They are sent to an LSF platform to handle the parallel submission. Today I see that only one of the blocks (the 19) has not finished

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 <-

Dear All, I'm not sure of the interpretation of interactions with contrasts. Can anyone help?

This patch adds mixed back ref support for btrfs programs. The mixed back ref is a new disk format. back compatilibity is still not implemented. To try the new disk format, you need fresh formatted btrfs.

Hi Folks, The question I'm asking, regarding the use of function definitions in the context described below, is whether there are subtle traps or obscure limitations I should watch out for. It is probably a rather naive question... Quite often, one has occasion to execute interactively a lot of R commands in which, from time to time, one has occasion to repeat exactly a sequence of commands

Hello, I’m Andrew Litteken, and I am working on a framework for defining, detecting, and deduplicating similar code sections at the IR level. Programmers can introduce sections of code that perform nearly the same operation. By copying and pasting code throughout a code base, or using a piece of code as a reference to create a new piece of code that has nearly the same structure redundancies
