ARMCI problem on SGI Altix

Dear NWChem users,

I've had the problems with NWChem which I describe here:

http://tiger.chem.uw.edu.pl/staff/lrajchel/nwchem_post.txt

(I cannot describe them here as I keep getting the "The specified URL cannot be found" error on the webpage on several browsers, maybe that's attributed to the NWChem web page settings. The funny thing is that it suffices to write c.mpile word in starting the new thread to get that error (replace . with o, of course). But that's another story.)

Sorry about this strange workaround to post my thread and thanks for your replies.

You specify ARENA as the ARMCI_NETWORK? I don't believe that network exists as a choice. This might be your root cause...

Dear Bert,

I tried using other options for ARMCI_NETWORK or simply leaving the variable blank - none solution worked.

Lets go step by step here:

Tell me about your cluster. What are the processors, what is the interconnect?

Bert

High-performance, shared-memory SGI® NUMAlink® interconnect for unparalleled I/O at 6.4GB/second

It's the SGI Altix 350 Cluster with 16 Itanium processors

cat /proc/cpuinfo
...
processor  : 15
vendor     : GenuineIntel
arch       : IA-64
family     : Itanium 2
model      : 1
revision   : 5
archrev    : 0
features   : branchlong
cpu number : 0
cpu regs   : 4
cpu MHz    : 1500.000000
itc MHz    : 1500.000000
BogoMIPS   : 2239.75

The interconnect is NUMAlink, according to the SGI website:



Some more info:

uname -a

Okay,

You should try the following:

1. make realclean

2. Unset ARMCI_NETWORK

3. make NWChem

Can you log your compilation and send it to me if it fails again.

Hi Bert,

I cleared the ARMCI_NETWORK variable, cleared the NWChem tree and recompiled - it finished with the same error as before, and the complete compilation log is here.

Thanks for the help so far!

That's weird, this should not even have been set with Itanium processors.

Can you do a "uname -m" on the node. It should say ia64.

Another way to eliminate is by unsetting USE_MPI, in tools do a make clean and make CC=icc FC=ifort, and a make link FC=ifort in src.
