similar to: ext3 and raw devices

Hello, We have an application that does a huge amount of disk i/o (mostly writes) and have hit performance problems. It seems that the use of O_DIRECT would help but information on the development status is hard to come by. I have checked 2.4.18 and 2.5 kernels and there seems to be an interface but no actual implementation. It has been suggested that it only works with ext2 but we need ext3.

Hi, We have been using ext3 with numerous machines and they take quite a bit of abuse without incident. This morning I got a call to say that a power cut had rendered one box unbootable. Investigations revealed that the /boot partition was in good order. An fsck of / also showed things to be well - except that the partition was completely empty - except for /lost+found. It might appear that

We are set up CENTOS 5.2 (X86) as our database server.? I created raw partitions and also put definition on /etc/sysconfig/rawdevices. I can use "raw -qa" see raw partitions.? The wield things is after reboot /dev/raw is not exist any more. ? Does anyone know how to fix it? ? Thanks.

Hi Dean, Thanks for your kind help. Since I couldn't use vpn in Intel and be a little late after I arrived home, I didn't get chance to modify the TAR on metalink. Tomorrow, I will go CDC and update it accordingly. We think all the problems should be caused by OCFS itself. There are two outstanding problem for now. First, we will get below error message when we issue "srvconfig

Hi, I have a cd building system that has worked for ages. I made lots of changes before I noticed that it now produces non-bootable cd's. I made changes to the files that went on the cd rather than the programs than buildings the isos (mainly mkisofs). The cd's don't fail on all machines. It seems to be a combination of motherboard and cd drive. At boot time, the cd light flashes

Hi all, I'm attempting to move the AddressSanitizer pass from the legacy PassManager to the new one because the new one has various benefits over legacy and wanted to clarify on something. Does creating the static RegisterPass struct register the pass with the new PassManager? It seems that RegisterPass does the same things that the INITIALIZE_PASS_* macros do but it registers the pass with

SRPMS are signed which allows the integrity of the contents to be checked. Such an integrity check is missing from the git repo. Either a checksum

I believe a good amount of them (if not most of them) have already been ported! Off the top of my head, I remember that asan, tsan, msan, hwasan, the kernel santizers, and sancov have been ported. I don't think ubsan has been ported yet though. You can also check if other passes you need run under the new PM by checking PassRegistry.def. On Fri, Aug 2, 2019, 14:20 Jordan Rupprecht

Hello team, Just wondering how the build of 5.10 is coming along. Is there a resource that informs us on these matters? Thanks! Regards, Leonard. -- mount -t life -o ro /dev/dna /genetic/research

Hi all, I merged from the monorepo master this morning and ran all tests and noticed that llvm/test/tools/llvm-nm/libtool-response-file.test was failing due to running out of memory. The test in particular just runs `llvm-nm --help` and running this prints the help info followed by endless whitespace. Has anyone else ran into this? Thanks, Leonard

Hi, I have a function foo(x,y) and a dataframe, DF, comprised of two vectors, x & w, as follows : x w 1 1 1 2 2 1 3 3 1 4 4 1 etc I would like to apply the function foo to each 'pair' within DF e.g foo(1,1), foo(2,1), foo(3,1) etc I have tried >apply(DF,foo) >apply(DF[,],foo) >apply(DF[DF$x,DF$w],foo) However, none of the above worked. Can anyone help ?

Hi all, We would like to propose a new Constant type in LLVM for representing entries in the Procedure Linkage Table (PLT). The PLT is a data structure used for dispatching position-independent function calls to appropriate functions where the address of the function is not known statically. Right now, if a call is made to a function, it may be lowered to a direct call to the function itself or

Hi Leonard, Fedor, while it's true that RegisterPass is not applicable for new-pm passes, PassRegistry.def is not the whole story. Passes in PassRegistry are available for the opt tool. The sanitizers are passes that usually get added to the pipeline by the frontend. There, you need to use PassBuilder's callbacks mechanism to hook the sanitizer into the optimizer. Assuming you're

I think so far most individual projects have their own statistics on build time/performance impact on switching to the new PM, but I agree that there should at least be one place that people can reference on the impact.

Hello all, As of now, all LLVM and Clang tests have been updated/addressed to run under the new/experimental pass manager (at least the ones that failed when using the new PM). For those who aren't aware of what the new pass manager (PM) is, the tl;dr is that this will serve as a replacement for the legacy PM, and promises faster build times by restructuring how passes are run over IR units.

My mistake! It does actually something else, which is incorrect. One could still use (although the code is more difficult to read): subset(tmp <- table(sample(1:10, 100, T)), tmp > 10) Sincerely, Leonard On 10/21/2023 10:26 PM, Leonard Mada wrote: > Dear List Members, > > There was recently an issue on R-devel (which I noticed only very late): >
