Subject: [StarCluster] Installing Intel compilers on Starcluster (UNCLASSIFIED)
Classification: UNCLASSIFIED
Caveats: FOUO
Dear Sir:
I am trying to install the Intel compilers on a Starcluster cluster on the Amazon Cloud using a free 30-day trial license. Basically I would like to take advantage of the AVX instruction set that the SandyBridge processors use on “cc2.8xlarge” instances. I was wondering if anyone had experience in installing the Intel compilers.
If an installation is successful, will I be using Intel MPI or OpenMPI?
I am starting with a 2-node cluster, so I created a “machines.LINUX” file with my two node names:
master
node001
but when I get to the command:
./sshconnectivity.exp machines.LINUX
it asks me for a password for “node001” which I don’t know. Then I tried to reduce the “machines.LINUX” file to just
master
and the installation “worked” in the sense that no error messages resulted. However I am worried that the MPI executables that I create with “mpiifort”, “mpiicc”, etc. will only run on the “master” node. I will be benchmarking the Amazon Cloud across a wide range of process counts, so it seems unreasonable to have to install the Intel compilers for each size cluster.
Should I close down the “node001” instance, and then add the desired number of nodes using
starcluster addnode -n <# additional nodes> mycluster
and starcluster will duplicate what I have done on “master”?
Finally, will I need a hostlist file (or “mpd.hosts” file) to run my MPI benchmarks under SGE? What is the format of the “mpd.hosts” file?
Thank you for any information.
Please excuse my novice-level questions. I appreciate any help.
