PAVPC运行脚本

最近做的代码改名字了，以前叫PVPC，现在干脆叫 PAVPC，即 projection after variation of pair condensate，这样可以区分开"projection after variation"和"variation after projection"。
现在给这个代码写一个脚本 run.sh，可以用来计算 \(sd\) 壳和 \(pf\) 壳的任意偶偶核的投影能谱和B(E2)值，只需给脚本传递 4 个参数即可：

#!/bin/bash
# ./run.sh x y sd nmini
# variation + LAP + B(E2) for x proton pairs and y neutron pairs in sd shell

pN=$1
nN=$2
shell=$3
nucleus=p${pN}n${nN}

jsp="example/$shell/$shell.jsp"
int="example/$shell/$shell.pn"
pjpair="output/best-proton.pair"
njpair="output/best-neutron.pair"

echo "======================================================================="
echo "             variation starts "
echo "-----------------------------------------------------------------------"
./pvpc.x << input

Input

echo cp output/$nucleus.trans sdpairs/
cp output/$nucleus.trans sdpairs/

赋予脚本可执行权限，然后：

./run.sh 1 1 sd 5

即对 Ne20 求 5 个低能的 pair condensate，然后取能量最低的，进行 LAP 投影，最后把最优的对命名为 pxnx-best-proton.pair, pxnx-best-neutron.pair，拷贝到 sdpairs/ 中，跃迁值命名为 pxnx.trans 也拷贝到 sdpairs/ 中。
如果需要一次算好几个核，可以使用下面的代码：

#!/bin/bash

sleep 30
date

for(( pN = 3; pN <= 3; pN ++ ))
do
        for(( nN = 1; nN <=5; nN ++ ))
        do
                time ./run.sh $pN $nN sd 5
        done
done
date

其中，sleep后面的参数是等待的秒数，设置适当的秒数，可以让办公室电脑等到晚上十点再启动，就不会打扰加班的同事。
