Hi All, I've recently dusted off my cross-compiling hat and decided to add R to the OpenEmbedded build environment (this is used to build the OpenZaurus/Familiar distributions for the Zaurus/iPAQ amongst other things - I note there's also work underway to add the Psion 5mx etc. to OpenEmbedded). OpenEmbedded builds now use -soft-float which makes floating point operations something like

Just wondering if there are any Zaurus owners out there using there zaurus as a voip phone?? I'm trying to decide which on to buy. The sl-6000 is perfect for phone use from what I've read, but it's not very pocket friendly (http://www.sharpusa.com/images/hpc_SL6000_pic1.jpg) The clamshell models (http://conics.net/shp/pda/zaurus-sl-c700/sl-c3000.html) are much nicer but would

For what it is worth, here are my experiences. When I first got my zaurus I compiled R version 1.4.0 for the it. It took some time to do, but managed with the skiffclusters at familiar.org. (libf2c was the hardest part). Compilation should be easier now that there are onboard compilers but I haven't tried. I thought this would be neat to have in the classroom. (It did get one student to buy

Hello, has anyone tried to get R running on a Sharp Zaurus 5500?

Hi again Sam, Sorry for not replying sooner. I have been ignoring everything for a while to work on the AMMP analysis tool and the continuing saga of migrating the legacy AMMP data. Our consultant has written some programs that take a VERY long time to run :( Anyway, I now know Java and a certain amount of JSP. I hope to be able to get around to this soon. It is all a bit hard now with our

Hello All, I have a working port of R on my SL5500. I've not tested the X windowing support yet, but was more concerned about the accuracy of the fp emulation. The following is the result of the test which Stuart Leask recommended I should try: Mandrake 8.2 > x<-NA > is.na(x) [1] TRUE > x+1 [1] NA > 2*x [1] NA Zaurus OZ3 > x<-NA > is.na(x) [1] TRUE > x+1 [1] 1

Hi, I am still new to R and have a programming question. I have created a small function which takes a parameter. In the function I want to be able to refer to the names of the variables sent to the function (specifically I want to be able to use the name of the variable given to the function in an output table). For example, in the following (fictional) function I want some way of printing

My test server was in very eavy load, running kolab's components: postfix, cyrus-imap and openldap A second test machine was sending, and reading emails as fast as it can. The CPU was never idle ! I left the server at about 17H30 and at 22H I find it "uncommitted" (difficult to work when the partition in read-only !) However the mount command report it as RW ! The /boot is still RW

Dear All, I have a working (in so far as NAs are handled correctly) version of R running on the Zaurus. The problem was not ieee 754 compliance but rather the fact that the configure script did not realise that the Z had a bigendian processor. I'll post a link, etc. tomorrow on the Zaurus forum for those who may be interested (http://www.zaurus.com/dev/board/) in downloading a copy.

Hello All, I read in the archives that someone managed to compile R but that there were problems with the fp performance, specifically the handling of NaNs. Could someone please explain the problem to me and how to test whether it is occurring. I have just compiled R for the Zaurus 5500, and want to see whether it works or requires tweaking. Regards, Simon

Hello All, A bit of a long one (background mainly), this is really just a request for some ideas. I ported R 1.7.x for use on the Sharp Zaurus (& iPAQ, simpad, yopy, etc.) some time ago and have just ported 1.8.1 but had never quite realised that you actually need to install some packages to make the system useful (I don't use R, I did it as a favour and of course for the fun of it). I

Hello All, The link to the binary & installation instructions (tar.gz binary not an ipk I'm afraid) is as follows: http://students.bath.ac.uk/enpsgp/Zaurus/#R It eventually dawned on me that the WORDS_BIGENDIAN define (or lack thereof) was causing the problems (after testing ieee NaN compliance that is). When cross-compiling it's probably fair enough that the configure script

Hi, guys, I am comparing the performance of the default scheduler (seems to be the one that minimizes register pressure) with no scheduler (-pre-RA-sched=none), and I got these numbers. The ratio is low_reg_pressure/none, that is, the lower the number, the better the performance with low register pressure: CFP2000/177.mesa/177.mesa 1.00 CFP2000/179.art/179.art

Perhaps you noticed that LLVM gained a new optimizing register allocator yesterday (r130568). Linear scan is going away, and RAGreedy is the new default for optimizing builds. Hopefully, you noticed because your binaries were suddenly 2% smaller and 10% faster*. Some noticed because LLVM started crashing or miscompiling their code. Greedy replaces a fairly big chunk of the code generator, so

Friday I enabled the inlinehint function attribute in the inliner. It mostly affects the performance of -Os compiled code. I have made some measurements on the SPEC test suite to show what it means. I made three runs of then nightly tests. The baseline represents -Os with no inlinehint: make TEST=nightly OPTFLAGS=-Os EXTRA_LOPT_OPTIONS=-inlinehint-threshold=0

Dear guys, After compiling 188.ammp, one of spec floating point benchmarks, using the linear scan register allocator, I got 34 spills, but only 28 store instructions. These data were given by -stats. Is this number correct? I mean, the number of stores should be equal or greater than the number of spills, shouldn't it? Best regards, Fernando

Hi, everyone! I am working on xen-4.2.0 with spice remote connect. My host is Fedora 14 and guest is win7. I have installed spice package and now I can connect to guest by spice client. For better graphics experience, I want to try the VGA passthrough. With spice tool, I have to create a VM by xl command, and now I am wondering if it supports VGA passghrouth? If so, how should I test it ?

Hi, Over the past six months, a MemorySSA-backed DSE implementation has been added to LLVM and it now covers almost all cases the existing DSE implementation does, plus adding a major new capability: eliminating stores across basic blocks. Thanks everyone involved with reviews, testing & patches! I think now would be a good time to start working towards switching to use MemorySSA-backed DSE
