We would like to announce the availability on CRAN of a new package multinomRob. It does robust estimation of overdispersed multinomial regression models. The package is also able to estimate overdispersed grouped multinomial logistic and multivariate-t logistic models. The code is relatively general; for example, it allows for equality constraints across parameters and it can handle datasets in

Dear everyone, I am trying to run rgenoud on several chips simultaneusly. I used the instructions provided on Jasjeet Sekhon's Homepage (http://sekhon.berkeley.edu/rgenoud/multiple_cpus.html). However, I have the newer version of R (R 2.12) installed - for a 64-bit machine. So, when I tried to install the special version of "snow" from a zip file provided by Jasjeet on his page, R

This patch introduces an optimized assembler version of md5_process(), the inner loop of MD5 checksumming. It affects the performance of all MD5 operations in rsync - including block matching and whole-file checksums. Performance gain is 5-10% depending on the specific CPU. Originally created by Marc Bevand and placed in the public domain, later integrated into OpenSSL. This is the original

First off I'll admit that I'm a bit of a newbie to Samba and Linux so sorry if this is a dumb question, but I had a look and couldn't find the answer anywhere. How do I map a username on a Windows 98 box to a different username on a Linux box? For example, if my username on a Windows machine was 'Daniel Foster' and my username on the linux box was 'dan' how do I make

Hi. I'm not a sysadmin, but I'm the only person in this building who knows anything about linux boxes. I'm trying to install samba to connect the box (rh7.3) to the windows network. test 8 is where I run into problems. My username and passwd are the same for both. My firewall is down. I have appended my .conf file. I've been searching around through the archives and

i'm trying to build a little summary table for the contents of a data frame. t<-sapply(macro, data.class) c<-sapply(macro, length) m<-sapply(macro, mean, na.rm=T, digits=2) cbind(type=t, n=c , mean=m) I want to drop the variables that are factors so I can include -max- and -min- in my table. -macro- contacts the data--how do I drop the variables according to their data.class

Hello everyone, In the file *lib/CodeGen/AsmPrinter/AsmPrinter.cpp*, I would like to obtain an MCInst corresponding to its MachineInstr. Can anyone tell me a way to do that? If that is not possible, then, I would like to know if a given MachineInstr is an *lea *instruction and I would like to know if the symbol involved with this lea instruction is a jump-table. For instance, given a

Was there any development on this? I noticed that clang still produces a lea for the testcase in llvm.org/pr13320.

Good morning in the Lord Regarding the port of libtheora1.1beta3 for OpenBSD for amd64 and the problem I described at: http://lists.xiph.org/pipermail/theora/2009-August/002640.html Attached is a patch for libtheora/patches/patch-lib_x86_mmxencfrag_c I can play videos with it. ?Does it work for you?

I've got a question about instruction selection for a backend I'm writing. The target has two register classes, RC1 and RC2. The instruction set is far from orthogonal. The ADD instruction is two address with both register/immediate and register/memory forms. The register operand is in the RC1 class. The LEA instruction is three address with the destination register in the RC2 class.

Hi, We are getting ready to implement several heuristics for correctly using LEAs to avoid stalls in the address generator on Atom. Our plan is to: 1. Disabling LEA generation on Atom in X86ISelDAGToDAG:: SelectLEAAddr() for all but a few pseudo-instructions 2. Identify loads and stores in a X86PassConfig::addPreEmitPass() pass and examine several preceding instructions to

Hi, Here is an update on our proposal to improve the uses of LEA on Atom processors. 1. Disable current generation of LEAs Due to a 3 cycle stall between the ALU and the AGU any address generation done using math instruction will cause a stall on loads and stores which are within 3 cycles of the address generation. Consequently, the heuristics for using LEAs efficiently must know how many

Hi all, I''ve been using Xen for a while and I am trying to install it onto a Dell Poweredge 2950. The 2850 uses a PERC4/Di raid on motherboard, which requires the LSI Legacy SCSI Raid driver to be compiled into the 2.6.11-xen0 kernel. I''ve been recompiling the kernel by: 1. Go into the linux-2.6.11-xen0 directory. Select the driver using "make ARCH=xen

I submitted the problem report to clang's bugzilla but no one seems to care so I have to send it to the mailing list. clang 3.7 svn (trunk 229055 as the time I was to report this problem) generates slower code than 3.5 (Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)) for the following code. It is a "8 queens puzzle" solver written as an educational example. As

The regressions in the performance of generated code, introduced by the llvm 3.6 release, don't seem to be limited to this 8 queens puzzle" solver test case. See... http://www.phoronix.com/scan.php?page=article&item=llvm-clang-3.5-3.6-rc1&num=1 where a bit hit in the performance of the Sparse Matrix Multiply test of the SciMark v2.0 benchmark was observed as well as others.

Actually there is no miscompile there as esi isn't needed. The flags are which the cmove is using. 342: shr esi,0x5 345: lea rbp,[rip+0x0] # 34c <llvm::sys::getHostCPUName()+0xbc> 34c: lea r12,[rip+0x0] # 353 <llvm::sys::getHostCPUName()+0xc3> 353: cmove rbp,r12 <- this is dependent on the flags from the shift.
