Getting mpiblast
  现在下载包文件:
 wget http://www.mpiblast.org/downloads/files/mpiBLAST-1.6.0-pio.tgz
 解压包文件:
 tar xvzf mpiBLAST*.tgz
 然后下载ncbi:
 
  wget ftp://ftp.ncbi.nih.gov/toolbox/ncbi_tools/old/20061015/ncbi.tar.gz
 
  解压包
 
  tar xvzf ncbi.tar.gz
Building mpiblast
将ncbi文件move:mv ncbi mpiblast/ncbi/make/
前进至mpiblast目录:
   cd mpiblast
 
  ./ncbi/make/makedis.csh
 
(Note: If you receive an error about CSH, you don't have the C shell installed, but that's easy to fix withapt-get install csh.)
The above command (makedis.csh) needs to be run three times. The first time you run, it will finish with an error:
make: *** No rule to make target `ncbimain.o', needed by `libncbi.a'. Stop.Fatal error building NCBI core libraries. Please be sure that you have X11 and Motif libraries installed. The NCBI toolkit FAQ at ftp://ftp.ncbi.nih.gov/toolbox/FAQ.html may be helpful.
Run the same command again,
- ./ncbi/make/makedis.csh
even though it finished with an error. This time, it will take quite a bit longer, and it will finish with a different error:
make: *** No rule to make target `ni_debug.o', needed by `libnetcli.a'. Stop. FAILURE primary make status = 0, demo = 0, threaded_demo = 0, net = 2 ####### # ##### ##### #### ##### # # # # # # # # # ##### # # # # # # # # # ##### ##### # # ##### # # # # # # # # # ####### # # # # #### # #
Run
- ./ncbi/make/makedis.csh
one last time, and it should finish successfully:
Put the date stamp to the file ../VERSION ********************************************************* *The new binaries are located in ./ncbi/build/ directory* *********************************************************
Then it's safe to continue on to building mpiblast itself.
安装mpiblast(安装在/usr/bin):
 
 ./configure --prefix=/usr/ --with-ncbi=`pwd`/ncbi --host=x86_64
 make 
 
 make install
 
 检查是否安装成功:
 which mpiblast
更新一下:
 
updatedb
 
locate mpiblast | grep -v src
 
进入当前用户的home路径(如果是一root进入,则进入/root,否则进入home)编辑.ncbirc:
[mpiBLAST] Shared=/usr/bin/mpiblast Local=/usr/bin/mpiblast
Getting Databases:
- wget ftp://ftp.ncbi.nlm.nih.gov/blast/db/FASTA/drosoph.nt.gz
Then you'll need to untar or just ungzip them. If they end in .tg.gz, use to tar to untar the file:
- tar xvzf yourfile.tg.gz
If they just end in .gz, they're only gzipped, so unzip them with
- gunzip yourfile.gz
安装
 1) 下载openmpi
 2) tar -xzvf openmpi-1.4.3.tar.gz
 3) cd openmpi-1.4.3 
 4) ./configure --prefix=/usr/ | tee ../install.log
 5) make all | tee ../make.log
 6) make install | tee ../install2.log
配置环境
 7) vi /etc/ld.so.conf  最后增加一行 
 /usr/bin
 保存退出
 8) /sbin/ldconfig   回车等待。
 9) vi /etc/profile, 最后 增加一行:
 PATH=${PATH}:/usr//bin
 保存退出
10)执行
 . /etc/profile
测试
 10)cd examples
 11) make
12) mpirun -np 4 ./hello_f90 可以得到类似ppt中的输出
mpi多机时, 需要有machines文件。文件内容如下:
tp1 1 /home/pact/mpich/examples/basic/cpi
 tp2 1 /home/pact/mpich/examples/basic/cpi
 tp3 1 /home/pact/mpich/examples/basic/cpi
分别表示机器名/ip, 进程个数, 进程名(进程名可以没有); 当使用机器名时, 则需要架设DNS服务器。
mpirun -machinefile ./machine.linux -np 4 ./hello_f90
OK:
使者运行一下:
- mpiformatdb -i drosoph.nt --nfrags=4 -pF
- -ispecifies my input file, drosoph.nt
- --nfrags=4tells it to make four fragments
- -pspecifies whether the file is a protein file or not. I put F for false, since this is a nucleotide file, not an amino acid file.
Mpiblast will be run just using mpirun or mpiexec, but there are a few important command line arguments. These include
- -d- the database to be queried against
- -i- the input file
- -p- the type of blast query to run, including- blastnfor nucleotides
- blastpfor proteins
 
- -o- the name of the file to save the output in
The command run in its complete state should look something like this:
- mpiexec -np 4 /shared/bin/mpiblast -d drosoph.nt -i test.in -p blastn -o results.txt
Of course, if you're using the version of mpiexec with Torque functionality, you'll need to wrap this in a qsub script.
When it's finished running, you should have a new results.txt file that looks something like this:
