So I guess that I have to configure my firewall (I use firehol):
I have just tried but without success. I will try again later.
Is there any other ports than the SLURM ones which are involved ?
On the SLURM side, you have to open the ports to the SLURM control
daemons and the service that handles the credentials. On Debian systems
that's MUNGE.
The SLURM part seems to be fine, as I used for nearly one year.
Also, you need to open ports for the MPI processes to communicate. The
port range is rather wide, so the easiest setup (I guess) is to not use
a firewall between computing nodes.
Indeed, but I do not like the idea as far as ``my'' cluster is concerned.
I realized this part of the story before to read the email.
On version 1.3.0 , there is new options which allow to specify
the open ports: [oon|btl]_tcp_port_[min|rnage]_v4
I have just tried the Sid package (1.3-2), but it does not work properly
(when the firewall are off)
I get (orange being the name of the node)
[orange:17336] bind() failed: Permission denied (13)
[orange:17336] mca_oob_tcp_init: unable to create IPv4 listen socket: Error
.........................
I have just read that the current stable version for OpenMPI is now 1.3.1:
I will give it a try once it will be packaged in Sid.
Best regards
Manuel
