Hi: I'm building a small tool on top of LLVM Core Library. ``` LLVMContext context; SMDiagnostic diag; Module *M = parseIRFile(InputIR, diag, context).get(); if (M == nullptr) { diag.print("LLVM", errs()); exit(-1); } assert(M->isMaterialized() && "Module not materialized!"); PointerType *ArrayPtrTy =

Hi, This is Crystal. I have some questions about llvm-gcc. Could you please give me some advice? Thanks in advance. Problem description: Env: llvm-gcc (GCC) 4.2.1 gcc (GCC) 4.1.2 OS:fedora7 I tried to compile a C programme test.c with llvm-gcc by task: [root at localhost mylib]# llvm-gcc -emit-llvm test.c -Llibmylib.a -c -o test.bc [root at localhost mylib]# lli test.bc after running the command

Hello, I 'd like to use some functions in myLib. So I do: library(myLib) Then I get this message: Error: package 'myLib' is not installed for 'arch=i386' > sessionInfo() R version 2.13.2 (2011-09-30) Platform: i386-pc-mingw32/i386 (32-bit) locale: [1] LC_COLLATE=French_France.1252 LC_CTYPE=French_France.1252 LC_MONETARY=French_France.1252 LC_NUMERIC=C

I am using the .Call interface to call c++ code from R. For that, I am trying to create a dynamic library (mylib.so) using "R CMD SHLIB" by linking my own c++ code and an external c++ library (blitz++). The makefile works fine on my Mac, produces mylib.so and I am able to call .Call() from R, but on a linux server (I think Debian), I got the following error: ---------- /usr/bin/ld:

hi all, i posted a question before about this, but i may have been too cryptic to understand. in short, there exists an R package that someone is writing. this package depends on a custom library (written in C,), compiled as a shared, and called by the package's functions via the .Call(...) method. we are testing out different code implementations of the compiled library functions, and thus

Looking at /tools/llvm-link/llvm-link.cpp may give you some ideas here. I havent looked at your specific use case, but llvm-link uses ParseIRFile to pull in a bitcode file and build a Module for it. You can then create a Composite using the Module * and call Linker::LinkModules(Composite.get(), NewModuleToLink.get()... to link a new Module to your Composite Module. -Chris On Feb 14, 2013, at

Dear All : Under Sun Storage 7000 system, can we see per share ratio after enable dedup function ? We would like deep to see each share dedup ratio. On Web GUI, only show dedup ratio entire storage pool. Thanks a lot, -- Rex -- This message posted from opensolaris.org

Is there an easy way to find out what datasets have dedup''d data in them. Even better would be to discover which files in a particular dataset are dedup''d. I ran # zdb -DDDD which gave output like: index 1055c9f21af63 refcnt 2 single DVA[0]=<0:1e274ec3000:2ac00:STD:1> [L0 deduplicated block] sha256 uncompressed LE contiguous unique unencrypted 1-copy size=20000L/20000P

I tried the deduplication feature but the performance of my fileserver dived from writing 50MB/s via CIFS to 4MB/s. what happens to the deduped blocks when you set dedup=off? are they written back to disk? is the deduptable deleted or is it still there? thanks -- This message posted from opensolaris.org

Dear R users, we are trying to build a R package that includes a precompiled shared library, let's say mylib.so. We created the skeleton of the package and we moved the mylib.so file into the libs folder that we created at the same level of the folders man and R. Moreover we created the file NAMESPACE and we added the line useDynLib(mylib, .registration=TRUE). The building step seems to work

Hello. I am looking to see if performance data exists for on-disk dedup. I am currently in the process of setting up some tests based on input from Roch, but before I get started, thought I''d ask here. Thanks for the help, Janice

Hello ZFS experts: I would like to study ZFS de-duplication feature. Can someone please let me know which directory/files I should be looking at? Thanks in advance. -- This message posted from opensolaris.org

Hi all Has anyone done any testing with dedup with OI? On opensolaris there is a nifty "feature" that allows the system to hang for hours or days if attempting to delete a dataset on a deduped pool. This is said to be fixed, but I haven''t seen that myself, so I''m just wondering... I''ll get a 10TB test box released for testing OI in a few weeks, but before

This article raises the concern that SSD controllers (in particular SandForce) do internal dedup, and in particular that this could defeat ditto-block style replication of critical metadata as done by filesystems including ZFS. http://storagemojo.com/2011/06/27/de-dup-too-much-of-good-thing/ Along with discussion of risk evaluation, it also suggests that filesystems could vary each copy in some

I'm new to spatial analysis and am exploring numerous packages, mostly enjoying sp, gstat, and spBayes. Is there a function that allows the user to dedup a data set with multiple values at the same coordinates and replace those duplicated values with the mean at those coordinates? I've written some cumbersome code that works, but would prefer an efficient R function if it exists.

Hi all Deduplicating data is not really a new thing, but quite efficient in mail systems where an email with an nMB attachment may be sent to multiple recipients. This might call for deduplicating data. Is there a way to do this, or is it far off? If I understand the system correctly, usually an MTA is calling dovecot on every single message, meaning the message itself won't

Greetings Gentlemen, I''m currently testing a new setup for a ZFS based storage system with dedup enabled. The system is setup on OI 148, which seems quite stable w/ dedup enabled (compared to the OpenSolaris snv_136 build I used before). One issue I ran into, however, is quite baffling: With iozone set to 32 threads, ZFS''s ARC seems to consume all available memory, making

Hi, Standard approach to profiling dynamically loaded libraries with gprof doesn't seem to work with LLVM: export LD_PROFILE=Mylib.so export LD_PROFILE_OUTPUT=. make ENABLE_PROFILING=1 // compiling my project opt -load Profile/Mylib.so -options... but no Mylib.so.profile (or gmon.out) is produced. Profiling libc.so.6 usage by "ls -l", however, works fine. Could anyone explain
