Hi all, I have a matrix of counts for objects (rows) by samples (columns). I aimed for about 500 counts in each sample (I have about 80 samples) and would now like to rarefy these down to 100 counts in each sample using simple random sampling without replacement. I plan on rarefying several times for each sample. I could do the tedious looping task of making a list of all objects (with its

I set up a domU as a backup server, but it has very, very poor network performance with external computers. I ran some tests with iperf and found some very weird results. Using iperf, I get these approximate numbers (the left column is the iperf client and the right column is the iperf server): domU --> domU 1.77 Gbits/sec (using 127.0.0.1) domU --> domU 1.85 Gbits/sec (using domU

I have backgroundrb working locally and everything''s fine. However, i can''t get it running on our server. I read a blog post by David Burger about backgroundrb (http://david-burger.blogspot.com/2008/04/backgroundrb-rails-notes.html#comment-form) and it says that you set up your backgroundrb.yml file with a different section for each environment you want to use. Mine looks like

Well, the worm has turned and I think I may actually get an Apple ;P. But I can''t decide which one. Pros and cons: 14" iBook: + modem (for when broadband kicks out, or on the road and there''s no WIFI) + screen is probably big enough (though I currently have a 15" Dell) + doesn''t get as hot as the MacBook + almost half the cost + less likely to get stolen -

I'm trying to use rsync to copy files from a Microsoft Windows machine (XP, with cygwin) to a macintosh (10.5.8, PPC). After a lot of playing with options, manual page reading, etc, I have the following command, executed on the windows machine: rsync -A -X -a --delete --rsync-path="/opt/local/bin/rsync --fake-super --log-file=/tmp/rlog.txt" /cygdrive/c/DRIVERS "rsync at

This is way OT, but here goes... I''ve had an iBook for 2 days now and am debugging a web built with prototype/script aculo / windows / etc... I have no real experience on a Mac. Occasionally, there''s no better way to debug JavaScript than an alert in a loop... Once I have the information information I want from the alert, the loop may want to execute another 300 times. I

This is an operating system question, but it is with the intent of using R on that operating system. I have an ibook G4 Power PC that I am going to install linux on. Is there a better, worse, or perhaps easier (I am a linux newby migrating from mac) distribution that I should look at. I appreciate your help. I didn't post this in the sig-mac because I don't know if it fits there better

You need to insert new basic blocks and update CFG to accomplish this. There is a hackish way to do this right now. Add a pseudo instruction to represent this operation and mark it usesCustomDAGSchedInserter. This means the intrinsic is mapped to a single (pseudo) node. But it is then expanded into instructions that can span multiple basic blocks. See

PPCTargetLowering::EmitInstrWithCustomInserter has a reference to the current MachineFunction for other purposes. Can you use MachineFunction::getRegInfo instead?

Hi Gary, This does not patch cleanly for me (PPCISelLowering.cpp). Can you prepare a updated patch? Thanks, Evan On Jul 10, 2008, at 11:45 AM, Gary Benson wrote: > Cool, that worked.

Just cast both values to const TargetRegisterClass*.

Hi, I've been looking at improving atomicrmw & cmpxchg code more, particularly on architectures using the load-linked/store-conditional model. The summary is that current expansion for cmpxchg seems to happen too late for LLVM to make meaningful use of the opportunities it provides. I'd like to move it earlier and express it in terms of a first-class pair of "load linked"

Would it be acceptable to change MachineInstr::getRegInfo from private to public so I can use it from PPCTargetLowering::EmitInstrWithCustomInserter?

Hi all, I'm very new to R and I'm trying to construct a threaded binary tree using recursive functions. I'm very confused was wondering if anyone had any R sample code they would share. I've come across a lot of C++ code(nothing in R) and this is not helping. best, MK -- View this message in context:
