[SSC]本地BLCR环境安装配置
Aug 2nd
本机实验环境：同上一篇LAM/MPI环境
- 配置，编译，安装BLCR
- tar zxvf blcr-0.8.2.tar.gz
- cd blcr-0.8.2
- ./configure --prefix=/usr/local/blcr
- make
- sudo make install
- 测试构建
- make insmod check
- 加载模块（两个）
- sudo /sbin/insmod /usr/local/blcr/lib/blcr/"uname -r"/blcr_imports.ko
- sudo /sbin/insmod /usr/local/blcr/lib/blcr/"uname -r"/blcr.ko
[SSC]本地LAM/MPI环境安装配置
Aug 2nd
本机实验环境：
- Ubuntu 9.04（Kernel-Version：2.6.28-19-generic）
- GCC-Version：gcc-3.4
- G++-Version：g++-4.1
注意：内核版本建议在2.6.30以下，默认GCC版本gcc-4.3过高，无法编译lam/mpi，这里使用gcc-3.4，同样G++使用g++-4.1
- 更改GCC、G++编译器版本
- cd /usr/bin
- ll | grep gcc
- ll | grep g++
- sudo apt-get install gcc-3.4
- sudo apt-get install g++-4.1
- sudo rm gcc
- sudo ln -s gcc-3.4 /usr/bin/gcc
- sudo rm g++
- sudo ln -s g++-4.1 /usr/bin/g++
First Batch of Parts for “Tianhe-1” Under Trial Use
Jan 19th
As http://www.hpcwire.com reported on January 14 2010, it was learned from the National Supercomputing Center in Tianjin January 13 that the adjustment of the first parts to be installed in “Tianhe-1,” China’s first supercomputer which is capable of doing more than a quadrillion calculations per second, has been completed.
This signifies that the supercomputer is qualified to provide service for clients and the first parts to be installed in “Tianhe-1″ have been in trial use among important clients.
The calculation capability of the first “Tianhe-1″ systems that have already reached Tianjin is one-tenth of a fully-installed “Tianhe-1.”
Fixstars Releases Beta of ‘FOXC’ OpenCL Compiler for x86
Jan 14th
As http://www.hpcwire.com reported on December 16 2009, Fixstars Corporation announced the release of the beta version of its OpenCL Compiler "FOXC" for the x86 architecture starting today. This will allow software developers to take full advantage of multicore x86 CPUs to develop OpenCL-based softwares. The "FOXC" Beta version can be downloaded for free from its Web site.
OpenCL is a parallel computing framework for programming multicore systems, such as multicore CPUs, GPUs, Cell/B.E., DSPs. The framework, which is a product of joint effort by the world’s leading semiconductor makers and hardware vendor, is attracting attention as an efficient and highly portable open technology for software development.
Google To End Censorship In China
Jan 14th
"We recognize that this may well mean having to shut down Google.cn and potentially our offices in China."
— David Drummond, Google chief legal officer
"While removing search results is inconsistent with Google’s mission, providing no information… is more inconsistent with our mission."
— Google statement
There’s no doubt that this is another tragedy after the Baidu’s being attacked. The Google staff in China even felt that they were abandoned.
Google, the world’s leading search engine, has thrown down the gauntlet to China by saying it is no longer willing to censor search results on its Chinese service.
The internet giant said the decision followed a cyber attack it believes was aimed at gathering information on Chinese human rights activists.
