クラス DSMMPI

java.lang.Object

io.github.kensuke1984.kibrary.external.DSMMPI

public final class DSMMPI
extends java.lang.Object

Utility for execution of DSM software such as tish and tipsv .
They must be in PATH. When you run, mpirun also must be in PATH.

All standard write and standard error will be thrown in the same way as the current process.

The MPI process will run in the same directory as an input information file, so that you do not care about working folder. (If your information file is tricky, ... ...)

メソッドの詳細

tipsv

public static java.util.concurrent.Callable<java.lang.Integer> tipsv(int np,
                                                                     java.nio.file.Path information)

Executes: mpirun -NP `NP` mpi-tipsv < `information` Before the execution, current directory will be the same as the `information` Note that 'mpi-tipsv' must be in $HOME/bin

パラメータ:

np - the number of MPI thread

information - for DSM (tipsv)

戻り値:

Callable<Integer> for tipsv returning value is exit code.

tish

public static java.util.concurrent.Callable<java.lang.Integer> tish(int np,
                                                                    java.nio.file.Path information)

Executes: mpirun -NP `NP` mpi-tish < `information` Before the execution, current directory will be the same as the `information` Note that 'mpi-tish' must be in PATH (checked by which).

パラメータ:

np - the number of MPI thread

information - for DSM (tish)

戻り値:

Callable<Integer> for tish and its returning value is exit code.

main

public static void main(java.lang.String[] args)
                 throws java.nio.file.NoSuchFileException

Example: -NP 8 -psv hogePSV.inf fooPSV.inf -sh hogeSH.inf fooSH.inf -NP is optional. Default is the number of threads in user's environment.

パラメータ:

args - arguments for DSMMPI

例外:

java.nio.file.NoSuchFileException - if any
