pwscf并行計算時總是隔一段時間重新開始
|
||
|
我讓學(xué)校網(wǎng)管幫我裝了并行的pwscf,我對怎么編譯并行不懂,用來計算小的體系的時候運行正常,但是算大體系的時候總是運行十幾分鐘之后重新提交任務(wù),也不報錯,不停重復(fù)。大家知道這會是什么原因嗎?謝謝了。!下面是我提交的任務(wù)腳本: #!/bin/bash -l #PBS -N MPI #PBS -l walltime=20:00:00 #PBS -l select=3:ncpus=16:mem=120gb module load quantum/5.0.MPT cd $PBS_O_WORKDIR mpiexec -n 48 pw.x < ZnO-k01.in > ZnO-k01.out 輸出文件的開頭: Program PWSCF v.5.0 starts on 10Jul2012 at 16:24:40 This program is part of the open-source Quantum ESPRESSO suite for quantum simulation of materials; please cite "P. Giannozzi et al., J. Phys.:Condens. Matter 21 395502 (2009); URL http://www.quantum-espresso.org", in publications or presentations arising from this work. More details at http://www.quantum-espresso.org/quote.php Parallel version (MPI & OpenMP), running on 768 processor cores Number of MPI processes: 48 Threads/MPI process: 16 R & G space division: proc/pool = 48 Current dimensions of program PWSCF are: Max number of different atomic species (ntypx) = 10 Max number of k-points (npk) = 40000 Max angular momentum in pseudopotentials (lmaxx) = 3 Waiting for input... Reading input from standard input Message from routine iosys: pot_extrapolation='second_order' not available, using 'atomic' Message from routine iosys: wfc_extrapolation='second_order' not available, using 'atomic' Subspace diagonalization in iterative solution of the eigenvalue problem: scalapack distributed-memory algorithm (size of sub-group: 4* 4 procs) Parallelization info -------------------- sticks: dense smooth PW G-vecs: dense smooth PW Min 869 348 87 364063 92078 11515 Max 870 349 88 364082 92147 11528 Sum 41737 16729 4177 17475363 4421473 552847 總是運行一會就重新提交任務(wù),輸出文件結(jié)尾也看不到錯誤。 |

不知道啊,管理員說是用3個node,每個node是16個cpu,120gb mem。不過我昨天修改了下輸出文件,運行時間長了點,好像還是會重新提交。修改后原來輸出文件里下面的錯誤沒有了 pot_extrapolation='second_order' not available, using 'atomic' Message from routine iosys: wfc_extrapolation='second_order' not available, using 'atomic' 不過還是有下面這行: Subspace diagonalization in iterative solution of the eigenvalue problem: scalapack distributed-memory algorithm (size of sub-group: 4* 4 procs) 您知道這是什么意思嗎?我覺得這是出錯信息。謝謝! |
