linux gaussian怎麼安裝linda

一、 背景介紹
Gaussian是目前計算化學領域內最流行、應用范圍最廣的商業化量子化學計算程序包。它最早是由美國卡內基梅隆大學的約翰·波普(John A Pople, 1998年諾貝爾化學獎)在60年度末、70年代初主導開發的。其名稱來自於該軟體中所使用的高斯型基組。最初,Gaussian的著作權屬於約翰·波普供職的卡內基梅隆大學;1986年,約翰·波普進入美國西北大學後,其版權由Gaussian,Inc.公司所持有。Gaussian軟體的出現降低了量子化學計算的門檻,使得從頭計算方法可以廣泛使用,從而極大地推動了其在方法學上的進展。
到目前為止,Gaussian已經推出了12個版本,包括Gaussian70、Gaussian76、Gaussian80、Gaussian82、Gaussian86、Gaussian88、Gaussian90、Gaussian92、Gaussian92/DFT、Gaussian94、Gaussian98、Gaussian03等,其版本數字也是該版本發布的年份。其中,每個版本發布後,還陸續發布了一些這些版本的修訂版。目前最新的版本是Gaussian03 Revision D.01/D.02。
Gaussian程序是用FORTRAN語言編寫的,它從量子力學的基本原理出發,可計算能量、分子結構、分子體系的振動頻率以及大量從這些基本計算方法中導出的分子性質。它能用於研究不同條件下的分子和反應,包括穩定的粒子和實驗上難以觀測的化合物,例如瞬時的反應中間物和過渡結構。
Gaussian的並行模式是採用OpenMP來實現的。OPENMP的並行實現是針對共享內存的機器的,實現方法簡單。因此Gaussian在共享內存的機器上,能獲得很好的性能。對於跨節點的計算,Gaussian使用TCP Linda軟體來實現。TCP Linda是一個虛擬共享內存的並行執行環境,它可以把一個通過網路連接的分布式內存的機群或工作站虛擬成共享內存環境,從而使像Gaussian這樣的用OPENMP實現並行的程序能夠在分布式內存的機器上運行。

二、 軟體的安裝設置
1、將壓縮包解開
# tar zxf OPT-900N.taz //g03 E01以上版本支持上海處理器 (可以查看文件日期在2007年以後的)

2、准備環境變數文件g03.sh

放入g03源代碼目錄,如/home/users/mjhe/g03/

#cat g03.sh

g03root="/home/users/mjhe"

GAUSS_SCRDIR="/scratch"

export g03root GAUSS_SCRDIR

. $g03root/g03/bsd/g03.profile

3、准備運行腳本
放入算例目錄,如g03test

> cat g03.pbs

###########################################################################

# Script for submitting parallel Gaussian 03 jobs to Dawning cluster.

# Lines that begin with #PBS are PBS directives (not comments).

# True comments begin with "# " (i,e., # followed by a space).

###########################################################################

#PBS -S /bin/bash

#PBS -N gaussian

#PBS -j oe

#PBS -l nodes=1:ppn=8

##PBS -l walltime=860:00:00

#PBS -V

##PBS -q middle

#############################################################################

# -S: shell the job will run under

# -o: name of the queue error filename

# -j: merges stdout and stderr to the same file

# -l: resources required by the job: number of nodes and processors per node

# -l: resources required by the job: maximun job time length

#############################################################################

INFILE=$file

# Define variable "jobname".

jobname=`echo $INFILE | awk -F. '{printf $1}'`

username=`whoami`

# Define the location where Gaussian was installed and run a setup script, g03.profile.

g03root="/data/users/ceszhcy/"

GAUSS_SCRDIR="/state/partition1/tmp/"

export g03root GAUSS_SCRDIR

. $g03root/g03/bsd/g03.profile

# Make a directory in scr and .com and .g03 file to there.

GAUSS_RUNDIR=${GAUSS_SCRDIR}/${username}.${PBS_JOBID}

if [ ! -a $GAUSS_RUNDIR ]; then

echo "Scratch directory $GAUSS_RUNDIR created."

mkdir -p $GAUSS_RUNDIR

fi

cp $PBS_O_WORKDIR/${jobname}.* $GAUSS_RUNDIR

ORIG_PBS_O_WORKDIR=${PBS_O_WORKDIR}

cd $PBS_O_WORKDIR

# Setup for Gaussian 03:

# =======================

# Make a scratch directory if it doesn't already exist.

GAUSS_SCRDIR=${GAUSS_SCRDIR}/${username}.${PBS_JOBID}/${jobname}

if [ ! -a $GAUSS_SCRDIR ]; then

echo "Scratch directory $GAUSS_SCRDIR created."

mkdir -p $GAUSS_SCRDIR

fi

export GAUSS_SCRDIR

echo "Using $GAUSS_SCRDIR for temporary Gaussian 03 files."

# Define node list

cat $PBS_NODEFILE|uniq > $GAUSS_SCRDIR/tsnet.nodes

NODE_NUM=`cat $PBS_NODEFILE|uniq |wc -l`

NP=`cat $PBS_NODEFILE|wc -l`

nodes=`cat $PBS_NODEFILE |uniq| awk '{printf("%s,",$1)}'`

sharecpu=`expr $NP / $NODE_NUM`

G03_NODEFILE="$GAUSS_SCRDIR/tsnet.nodes"

GAUSS_LFLAGS=" -mp 2 -nodefile $G03_NODEFILE"

export GAUSS_LFLAGS

echo pbs nodefile:

cat $G03_NODEFILE

#Run a Gaussian command file, water03.com, redirecting output to a file, water03.log

cd $GAUSS_RUNDIR

echo "%NProcShared=$sharecpu" > ${jobname}.Input.${PBS_JOBID}

if [ $NODE_NUM -ne 1 ];

then

echo "%LindaWorker=$nodes" >> ${jobname}.Input.${PBS_JOBID}

fi

grep -v nproc $INFILE |grep -v NProcShared |grep -v LindaWorker >>${jobname}.Input.${PBS_JOBID}

echo "Starting Gaussian run at" `date`

if [ $NODE_NUM -eq 1 ];

then

time g03 < ${jobname}.Input.${PBS_JOBID} > $GAUSS_RUNDIR/${jobname}.log

fi

else

time g03l < ${jobname}.Input.${PBS_JOBID} > $GAUSS_RUNDIR/${jobname}.log

fi

#time g03 < ${jobname}.Input.${PBS_JOBID} > ${jobname}.log

echo "Finished Gaussian run at" `date`

PBS_O_WORKDIR=${ORIG_PBS_O_WORKDIR}

echo $PBS_O_WORKDIR

mv $GAUSS_RUNDIR/${jobname}.* $PBS_O_WORKDIR

mv $GAUSS_SCRDIR/*.chk $PBS_O_WORKDIR

echo "$GAUSS_SCRDIR"

rm -Rf $GAUSS_SCRDIR

4、測試安裝是否成功
准備算例test397.com

在算例目錄下修改g03.pbs,然後執行qsub g03.pbs -v file=test397.com

cd ~/g03test

qsub g03.pbs -v file=test397.com

5、其他

三、 注意事項
1、本文命令、代碼和超鏈接採用斜體五號字表示
2、算例文件名必須有兩部分組成,前綴+後綴,中間用 . 隔開
3、需要修改一下兩個文件以適應linda並行時的配置情況:
#vi /data2/home/test/g03/linda7.2/opteron-linux-I8/bin/LindaLauncher

/mf/giovanni/static/g03/linda7.2/opteron-linux-I8/bin/cLindaLauncher

#vi /data2/home/test//g03/ntsnet

/mf/giovanni/static/g03/linda7.2/opteron-linux-I8/bin/true_ntsnet

4、在所以參與計算的節點根目錄上增加/scratch/,並設置開放的許可權
mkdir /scratch

chmod 777 /scratch

5、其他

⑤ 為什麼香港中文大學研發的人臉識別演算法能夠擊敗人類

LFW(Labeled faces in the wild[1])是人臉識別研究領域比較有名的人臉圖像集合,其圖像採集自Yahoo! News,共13233幅圖像,其中5749個人,其中1680人有兩幅及以上的圖像,4069人只有一幅圖像;大多數圖像都是由Viola-Jones人臉檢測器得到之後,被裁剪為固定大小,有少量的人為地從false positive中得到[2]。所有圖像均產生於現實場景(有別於實驗室場景),具備自然的光線,表情,姿勢和遮擋,且涉及人物多為公物人物,這將帶來化妝,聚光燈等更加復雜的干擾因素。因此,在該數據集上驗證的人臉識別演算法,理論上更貼近現實應用,這也給研究人員帶來巨大的挑戰。

⑥ 為什麼香港中文大學研發的人臉識別演算法能夠擊敗人類

1.全面超過人臉時的條件是實驗室內部拍攝條件、正面姿態、正面光照。這種條件下的人臉識別錯誤率的進展大約是每3年下降10倍。FRVT2012中期結果中最好的單位(不出意外應該是日本的NEC公司)的錯誤率已經達到了我們06年系統的1%左右。而我手上的系統相比06年大約提升了十幾倍,目前在中期結果中排名6-7名。
2.lfw資料庫直接是從雅虎網上抓的照片。難度在業界屬於頂尖。該庫09年公布後至今沒有難度更大的靜態照片庫出現。難度相當但數據量更大的庫倒是有兩三個。我們06年的系統跑lfw也就70+的水平。而我們實驗室的最高水平(也是國內除face++外的最高水平)大約是92左右。大概相當於2012年底的state-of-the-art。
3.2014年的三個逆天結果,deepface的97.25%、face++的97.27%、gaussianface的98.52%,前兩者都用了deep learning。第一個訓練數據400萬。第二個演算法細節不明,但deeplearning向來吃樣本,想來訓練庫也是百萬量級。唯有gaussianface的訓練庫僅2萬余。
4.arxiv和CVPR等頂會完全不矛盾。先發上來只是為了不讓別人搶先。估計未來的頂刊頂會上很快會出現這個結果。
5.演算法細節太過技術,難以在這里深入淺出,就不多介紹了。只提一篇paper。Blei的latent dirichlet allocation,2003年的jmlr,引用量近萬。本文對人臉的貢獻方式大概相當於lda對文檔分類的貢獻方式,懂行的人自然知道這句話的分量。當然lda珠玉在前,deep learning風頭正勁,所以真正的歷史地位,本文自然不可能趕上lda。但一篇正常pami的水準肯定是有的。

⑦ 哪裡能搞到Gaussian09的源代碼 source code

正對自己的平台,使用源碼編譯,執行效率比較高。
我對比測試的是G09A01 和G03D02 目前流出的D02是別同通過source code編譯的,
D02計算速度明顯快很多的...
