[SCore-users-jp] [SCore-users] IA32/IA64

[Nick Birkett]

I need some help getting a Intel Xeon / Itanium cluster to work.

I have an 16 node dual i386 cluster and a single 4 cpu Itanium
system both working with Score 5.4.0 with gigabit network/ shmem.

I have 2 binaries compiled and working for both architectures.

There is a .wrapper link :

nickb ＠ cserver ]$ ls -al ~/bin/hyd-3.04.027.par_op
lrwxrwxrwx    1 nickb    sc              8 Aug 21 12:00 /users/nickb/bin/hyd-3.04.027.par_op -> .wrapper

The binaries are 

/opt/score/bin/bin.i386-redhat7-linux2_4/hyd-3.04.027.par_op.exe
/opt/score/bin/bin.ia64-redhat-linux2_4/hyd-3.04.027.par_op.exe

I can run the wrapper program hyd-3.04.027.par_op on both machines successfully.

scout works across both platforms

[nickb ＠ cserver falcon]$ cat hosts
comp00.streamline
itanium00.streamline
[nickb ＠ cserver falcon]$ scout -F hosts
SCOUT: Spawning done.
SCOUT: session started.
[nickb ＠ cserver falcon]$ scout hostname
[comp00]:
comp00.streamline
[itanium00]:
itanium00.streamline


I have compiled scored.exe and scored_dev.exe to include ia64 symbols on the i386
front end server.

[nickb ＠ cserver bin.i386-redhat7-linux2_4]$ nm scored.exe | grep ia64

081a657c t elf64_ia64_size_dynamic_sections
081a7440 t elf64_ia64_unwind_entry_compare
082e945c b elf64_ia64_unwind_entry_compare_bfd
08252c00 r ia64_howto_table
081bac40 t ia64coff_object_p

I have both an i386 and ia64 bin and deploy directories on the front end:

[nickb ＠ cserver deploy]$ ls -ald bin.i*
drwxr-xr-x    2 root     root         4096 Aug 21 16:48 bin.i386-redhat7-linux2_4
drwxr-xr-x    2 root     root         4096 Aug 21 16:22 bin.ia64-redhat-linux2_4


This is the error I get when the hosts file has comp00 (i386) and itanium00 (ia64)

nickb ＠ cserver falcon]$ scout -F hosts -e scrun -nodes=4 ~/bin/hyd-3.04.027.par_op
SCOUT: Spawning done.
<1> ULT:ERROR Unable to open binary file (/opt/score/deploy/bin.ia64-redhat-linux2_4/scored.exe)=0

However the file /opt/score/deploy/bin.ia64-redhat-linux2_4/scored.exe is readable

[nickb ＠ cserver falcon]$ ls -al /opt/score/deploy/bin.ia64-redhat-linux2_4/scored.exe
-rwxr-xr-x    1 root     root     17489790 May 26 23:19 /opt/score/deploy/bin.ia64-redhat-linux2_4/scored.exe


Any help to make this work would be appreciated.

Thanks,

Nick
