[gfarm-discuss:09315] question about gfrun

["Yikuo Chan" <yikuo.chan@xxxxxxxxx>]

Hello : 

Because we need convert a lot of wav file to mp3 format at the same time so I  think maybe gfrun can help me on 
this challenge  . 

but unfortunately I meet below problem when test it : 

A.should
 I modify program before use gfrun to execute it ? some document say program can execute by gfrun without modify is that true ? my program look like didn't understand what is gfarm uri  , below is my log  :  

[
root@FWD-test root]# gfrun  gfarm:lame -b 16 --resample 22.05 gfarm:AS_20070302-154921.wav gfarm:AS_20070302-154921.mp3
Could not find "gfarm:AS_20070302-154921.wav".
[root@FWD-test root]# gfrun gfarm:lame --help
LAME 32bits version 3.97 (http://www.mp3dev.org/)

usage: gfarm:/root/lame [options] <infile> [outfile]

    <infile> and/or <outfile> can be "-", which means stdin/stdout.

RECOMMENDED:
    lame -V2 input.wav output.mp3

OPTIONS:
    -b bitrate      set the bitrate, default 128 kbps
    -h              higher quality, but a little slower.  Recommended.
    -f              fast mode (lower quality)
    -V n            quality setting for VBR.  default n=4
                    0=high quality,bigger files. 9=smaller files
    --preset type   type must be "medium", "standard", "extreme", "insane",
                    or a value for an average desired bitrate and depending
                    on the value specified, appropriate quality settings will
                    be used.
                    "--preset help" gives more info on these

    --longhelp      full list of options

[root@FWD-test root]# gfls -l gfarm:AS_20070302-154921.wav

 B.Authentication problem : on same platform I have no problem to use  gfarm system by root , but 
   when I use non-root user  system show "authentication error" , am I miss some thing ?

[kk1@asterisk1 kk1]$ gfhost | gfrun -H - hostname
gfrun: job manager: authentication error
[kk1@asterisk1
 kk1]$ gfps 
gfps: authentication error
[kk1@asterisk1 kk1]$ ls -l .gf*
-rw-r--r--    1 kk1      kk1           355 May 24 13:49 .gfarmrc
-rw-rw-r--    1 kk1      kk1            74 May 10 20:15 .gfarm_shared_key
[kk1@asterisk1 kk1]$ 
[kk1@asterisk1 kk1]$ gfreg  sample.txt gfarm:sample.txt-on-gfarm
[kk1@asterisk1 kk1]$ gfls -l gfarm:sample.txt-on-gfarm
-rw-rw-r-- kk1      *              2780 May 24 18:52 gfarm:sample.txt-on-gfarm
