I'll definitely be trying this out once I get a fully-stable vanilla setup up and running. Cheers! |
Glad you're enjoying it  We have been trying to get a hold of some patches that have been postulated to compile the kernel with Sun's compiler but have been unsuccessful in get a hold of anyone in development. I would doubt it would be faster than ICC but may be of benefit for exposing bugs. |
Believe it or not, it's actually considerably quicker at heavy maths, at least on the Nehalems... we'll have to see how it fares now that Intel's new line is out. You'd think otherwise, but I suppose when it comes down to it Oracle is the operation with the experience in optimizing the performance of algorithms in distributed node settings, so all they really need is the architecture to translate their existing IP to the particular application, whereas with Intel the case is just the opposite. |
Is there an ebuild?
@ darkbasic - sweet let me know how it goes

Couple of things... did you compile your icc kernel with: make AR=xiar LD=xild or simply with make?
Also how were the applications tested compiled? Did you try using ICC for any? If so did you employ IPO or PGO? These would make a big difference.

Just make.

I wanted to test just the kernel, so the applications binaries were the same (gcc-4.4.3).

I would retry with AR=xiar LD=xild
I imagine it would make at least a little difference.

For everybody who wants a 32bit patch:
wget http://www.linuxdna.com/dna-2.6.33-intel32-1.patch
Remember to use the correct source command when compiling:
ex:
source /opt/intel/Compiler/11.1/069/bin/iccvars.sh ia32
instead of:
source /opt/intel/Compiler/11.1/069/bin/iccvars.sh intel64

Not related with LinuxDNA, but...
Here are my questions:
1. Could I safely replace ld with xild for packages compiled with icc ? I mean: Will I break gcc compatibility ? What is the right way to do that ?
From what I found some people say that it's happen automatically, but it seem that ld from binutils is used if I don't specify AR=xiar LD=xild
My /etc/portage/bashrc from gentoo-wiki
| Code: |
export GCC=${OCC}
export GCXX=${OCXX}
export OCC="icc"
export OCXX="icpc"
export CFLAGS=${ICCCFLAGS}
export CXXFLAGS=${ICCCXXFLAGS}
[ -r ${ROOT}/etc/portage/package.gcc ] || return 0
while read -a target; do
if [ "${target}" = "${CATEGORY}/${PN}" ]; then
export OCC=${GCC}
export OCXX=${GCXX}
export CFLAGS="$flags"
export CXXFLAGS="$CFLAGS"
if [ -r ${ROOT}/etc/portage/package.gcc-cflags ]; then
while read target flags; do
if [ "${target}" = "${CATEGORY}/${PN}" ]; then
export CFLAGS="$flags"
export CXXFLAGS="$CFLAGS"
break
fi
done < ${ROOT}/etc/portage/package.gcc-cflags
fi
break
fi
done < ${ROOT}/etc/portage/package.gcc
# My add to script. Is that correct ? Will it work properly ?
if [ "${GCC}" = "icc" ]; then
export AR=xiar
export LD=xild
fi
if [ -r ${ROOT}/etc/portage/package.icc-cflags ]; then
while read target flags; do
if [ "${target}" = "${CATEGORY}/${PN}" ]; then
export CFLAGS="$flags"
export CXXFLAGS="$CFLAGS"
break
fi
done < ${ROOT}/etc/portage/package.icc-cflags
fi
if [ "${OCC}" != "" ]; then
export CC_FOR_BUILD="${OCC}" #workaround gcc detection function in toolchain-funcs.eclass
fi
unset GCC
unset GCXX
|
2. Does anyone have a list of Gentoo packages which compile fine with -ip and -ipo icc flags ?
Thank you!

You will need to add the flags like you have here. Once linked this way you will need icc to be installed of the binaries will not work... so in a sense it does break compatibility because it is now dependent on icc libs.

@Thaidog
That was my presumptions also, so I already compiled my world set using:
| Code: |
export GCC=${OCC}
export GCXX=${OCXX}
export OCC="icc"
export OCXX="icpc"
export CFLAGS=${ICCCFLAGS}
export CXXFLAGS=${ICCCXXFLAGS}
[ -r "${ROOT}"/etc/portage/package.gcc ] || return 0
while read -a target; do
if [ "${target}" = "${CATEGORY}/${PN}" ]; then
export OCC=${GCC}
export OCXX=${GCXX}
export CFLAGS="$flags"
export CXXFLAGS="$CFLAGS"
if [ -r ${ROOT}/etc/portage/package.gcc-cflags ]; then
while read target flags; do
if [ "${target}" = "${CATEGORY}/${PN}" ]; then
export CFLAGS="$flags"
export CXXFLAGS="$CFLAGS"
break
fi
done < "${ROOT}"/etc/portage/package.gcc-cflags
fi
break
fi
done < "${ROOT}"/etc/portage/package.gcc
if [ "${GCC}" = "icc" ]; then
# found="no"
# while read -a target; do
# if [ "${target}" = "${CATEGORY}/${PN}" ]; then
# found="yes"
# break;
# fi
# done < "${ROOT}"/etc/portage/package.icc-plain
grep "${CATEGORY}/${PN}" "${ROOT}"/etc/portage/package.icc-plain
if [ $? -eq 0 ]; then
found="no";
else
# if [ "${found}" = "no" ]; then
export AR=xiar
export LD=xild
export LDFLAGS="--as-needed,--warn-once,--sort-common,--hash-style=gnu"
fi
fi
if [ -r ${ROOT}/etc/portage/package.icc-cflags ]; then
while read target flags; do
if [ "${target}" = "${CATEGORY}/${PN}" ]; then
export CFLAGS="$flags"
export CXXFLAGS="$CFLAGS"
break
fi
done < ${ROOT}/etc/portage/package.icc-cflags
fi
if [ "${OCC}" != "" ]; then
export CC_FOR_BUILD="${OCC}" #workaround gcc detection function in toolchain-funcs.eclass
fi
unset GCC
unset GCXX
|

net-misc/openssh
sys-cluster/openmpi
www-apache/mod_security
|
and media-libs/gd which I have to add to package.gcc. It compile fine, but break media-gsx/graphviz (compile time, linking) and /dev-lang/php (runtime)

@darkbasic
Thanks, but it's not what I looking for. I know how to set flags per package.
I'm looking for a list of packages witch copile and perform stable using icc and -ip/-ipo flag.
Thank you, anyway.

Give Luyi an email:
luyi at linuxdna dot com
He has compiled a pure 64bit LFS atom based system and has much insight on what will compile with what flags... etc

Done that, waiting for response. Thank you!
More info about replacing ld with xild:
- system is more responsible
- so far, no segfault, no problems
- booting (until desktop) faster with 4.3 seconds
- mysql import a database ~2GB (sql dump) faster with 12.8 seconds
- revdep-rebuild check also quicker
- works fine with prelink
Conclusion: it's worth to use xild instead ld from binutils.
Anyway, I'm speaking from a user perspective. I'm Java and web developer so I don't know much about C/C++ except syntax
Next step: Find out packages which compile and works fine with ip/ipo icc's flag.
If anyone have a list with packages which compile or don't compile fine using this flag, please don't be shy. It's a long and time consuming process to find out package by package.
If someone it's interested about a stage4 backup (1.4GB - 7zip archive) I'll put that on a webserver. Unfortunately, I have only 1mbs upload speed.

i removed the compiler-intel.h section and edited by hand then patch applied but
make AR=xiar LD=xild && make AR=xiar LD=xild modules_install
hangs here forever;
CC arch/x86/kernel/cpu/powerflags.o
CC arch/x86/kernel/cpu/common.o
EDIT: disabled fstack-protector and it compiled.
so far it works but btrfs crashes.
i have tried the suggestions in the pages to no avail.

What I do to build the nvidia driver is I grab the latest one from nvidia.com and then I extract it using the -x flag. I then go to the usr/src/nv directory and I build the nvidia.ko driver using icc. Here is part of my build script for the nvidia driver:

This has been working fine for me with 64-bit dna-icc kernel but I have not had the chance yet to try it with 32-bit. |

What I do to build the nvidia driver is I grab the latest one from nvidia.com and then I extract it using the -x flag. I then go to the usr/src/nv directory and I build the nvidia.ko driver using icc. Here is part of my build script for the nvidia driver:
ROOT=/tmp/root.33 # Directory where I installed the kernel and modules
KROOT=/usr/src/linux-2.6.33.dna
NROOT=/usr/src/NVIDIA-Linux-x86_64-195.36.15-pkg2
cd $NROOT/usr/src/nv
make clean
make SYSSRC=$KROOT CC=icc module
mkdir -p $ROOT/lib/modules/$KERNEL/kernel/drivers/video
cp nvidia.ko $ROOT/lib/modules/$KERNEL/kernel/drivers/video
echo "kernel/drivers/video/nvidia.ko:" >> $ROOT/lib/modules/$KERNEL/modules.dep

i don't understand. let me have your script. thanks.
EDIT: tried but it doesn't load.

The script is an example. I posted the part that is relevant to building the nvidia driver. The full script may not run in Gentoo since I build on a different distribution (Slackware64). You will need to grab the nvidia drivers, extract them and then you can go to the source directory for the nvidia driver and build the driver. Here is an example of the steps I take when building the nvidia driver manually:
To extract the driver:
./NVIDIA-Linux-x86_64-195.36.15-pkg2 -x
cd NVIDIA-Linux-x86_64-195.36.15-pkg2/usr/src/nv
To build the driver:
make SYSSRC=/usr/src/linux CC=icc module
Replace /usr/src/linux with the kernel source directory that you built the icc kernel with.
Then to install:
make install
If all goes well, you can load the module and start X:
depmod -a
modprobe nvidia
startx |

doesn't work for me. driver installs but crashes.

No ebuild, but I haven't run into a single snag installing it from source, whether on OpenSolaris, Ubuntu, or Gentoo. Referring to SunStudio12U1 here. There is an RPM available for download, if you'd rather use that. |
