Hi , I am using the plot function for some data , and the plot is coming back pure black , with scales on the side . Regards Malcolm [[alternative HTML version deleted]]

...Using the LLVM Tool Chain examples on optimization step. 2. If i am not wrong there is no tool, which integrates all steps: llvmgcc->opt->llc into something like llcc (and llvmg++->opt->llc into something like ll++), where options -O1, -O2, -O3 are available. For example, `llcc -O3 ackerman.c' should make similar (but better!) things as `gcc -O3 ackerman.c' does. Anyway, it would be good to have a starting point for those who'd like to try "fully LLVM-optimized" C/C++ code. Indeed, the tool "opt" has quite big set of options... best regards, --- Valer...

You should be able to do this with the gccld -native or -native-cbe options: For example: $ llvmgcc ackerman.c -o ackerman -Wl,-native-cbe ... compiles to a native 'ackerman' executable, using the C ba...

...ok into LLVM benchmarks from nightly tester and ran Shootout tests on my own. Below go just few outlines. 1. results on my AMD AthlonXP and Xeon used by LLVM team are different sometime. In particular, both Shootout and Shootout-C++ show great speed up with LLVM (in comparison to GCC) on ackerman test on my AthlonXP. But here: http://llvm.cs.uiuc.edu/testresults/X86/ GCC is reported to be quicker on Benchmarks/Shootout-C++/ackermann test. 2. the tests based (e.g. ackerman,fibonacci) on function calls are tend to be quicker with LLVM then with GCC :) 3. some generic tests (...

This test seems PARTICULARLY noisy for some reason. Take a look at this: [zion Shootout-C++]$ time Output/ackermann.native Ack(3,...

I thought I had things figured out, but guess not. I have multi-user Quickbooks databases that functioned fine on a Novell server but are behaving badly on a Samba share. I have created a separate share for the Quickbook databases, users are running Win XP Pro, latest patches, and the Quickbooks application installed on the desktop. It is a multiuser version. Server is RedHat ES 3, Samba

...98-4.58s. FWIW, these tests are on a Intel P4 Xeon 3.06Ghz machine with > HT enabled. In any case, it appears that we're slower than GCC on this one. what is very funny, that the situation on my AMD is not similar at all to what you state here. On my side tests show GREAT spead up with ackerman, i.e. 2 to 3 times.

Hi, I have a plot that is essentially the same as that in Figure 5.6 of "Lattice - Multivariate Data Visualization with R". The key difference is that I would like to add a title to top of the grey color spectrum legend, but have thus far been unsuccessful. I've tried a variety of options, but to no avail. I'm new to R, and admittedly I don't understand the

Hello, I'm new to the list and pretty much a newbie to linux and samba. I'm quick learner though. I have been losing my samba share upon ocasion recently, below is a portion of the syslog from the time period that I think is when the share goes down. A reboot of the server or a restart of the smbd fixes the problem (....until it happens again) I don't know what SIGUP is or why

Hello, Is tail call optimization performed if the ret instruction does not actually follow the tail call? Not according to the documentation, but in examples it seems to work. For example, consider the following definition of Ackerman's function in ML (it has two tail calls): let rec ack x y = if x <= 0 then y + 1 else if y <= 0 then ack (x - 1) 1 else ack (x - 1) (ack x (y - 1)) My compiler is generating the following code for it: define internal fastcc i64 @ack.15(i64 %x.16, i64 %y.17) { entry: %0 = icmp...

I am new at Samba. I just about have it working. From my windows XP client, I can access the workgroup and then see the server. When I click on server to access network folders, the login pops up. I put in the username and password (both of which are already in Samba). The login window refreshes and I get in the login screen: XXX/username, with XXX being the name of my local Windows XP

The smb service is not starting automatically. I can type service smb start at the prompt and it loads, and I can then connect, but its not loading automatically as it used to. Can someone point me in the right direction as what file I need to change to make it load at startup. Thanks! Liz

I am running Samba 3 on RedHat Enterprise ES rel 3 on an Intel box. I read a man page about vfstest, but I am not able to find any such file on my system. Can someone direct me to where I might find this file? Thanks. Liz

...ropose ? oh, it is the worst form of Fibonacci function! it has O(2^n) complexity! There is a lot of optimization abilities even at single CPU, up to linear time and constant memory ;) However in this form it is a good model to discuss simple problems of distributed computations. (we could use Ackerman function as alternative) -- Valery

Hi, I'm new to R and new to this forum. I'm struggling with trying to extract certain rows of data from my data.frame. The data.frame has eleven columns. Among those columns are "FISH_ID" and "DATE_TIME". FISH_ID is a factor. For each of my 21 unique FISH_IDs (levels) I have a few to a few thousand rows, each row with a unique DATE_TIME value. I would like to obtain,

Hi there, Can somebody please explain to me why Samba 3 requires 'oplocks = no' on shares for programs like Quickbooks to operate properly with multiple users, where Samba 2 didn't? Without this option, Quickbooks will complain about file corruption when a second user tries to open a file. This option, however, makes the particular share that the option is present in _very_ slow
