[SCore-users] MPI-IO

[Nick Birkett]

Hi Score team. We seem to be having an MPI-IO problem with Score 5.4 x86 
RedHat 7.3.
The users files are NFS mounted from the front end (RedHat 7.3 x86)


----------  Forwarded Message  ----------

Here is an issue that one of our users discovered, which has only started
occuring with the new version of SCore.

I have remounted the nfs partition '/scratch' on all nodes with this noac
option:

(fstab)
server:/scratch    /scratch        nfs
rw,suid,dev,exec,auto,nouser,async,noac 0 0

(output from mount)
server:/scratch on /scratch type nfs
(rw,noac,addr=192.168.1.254)

The problem is still there.

Any ideas?

Thanks
