@1) We are now using lam for $WM_MPLIB but it also worked with openmpi for $WM_MPLIB

@2) can't remember, sorry

@3) yes, but if you set the number of cpus for compilation higer e.g. $WM_NCOMPPROCS=8 you will get some speedup (I think to the order of 2h or so)

Many thanks to Jens for help getting me started on the SGI/Altix. The use of WM_NCOMPPROCS was a BIG help! I am still having problems I am hoping to get help with...

The OS on the machine is SGI ProPack 4.0.3, with gcc version 3.3.3 and icc version 9.0. (Note it is a supercomputer resource). When compiling, openfoam uses icpc, and I set the WM_MPLIB flag to LAM. Here are some problems I hope someone can help with...

1) I get warning #1357: optimization disabled due to excessive resource requirements. Is there a way to get around this?

2) PatchTool gives lots of Java errors. I certainly don't need anything graphical to run on the SGI/Altix machine, so is there a way to turn off anything that uses Java?

3) decomposePar gives the following error:

undefined reference to `Foam::Cloud<foam::indexedparticle>::readFields()'

4) several mico errors:
ld: /u/ac/dhebert/OpenFOAM/OpenFOAM-1.3/src/mico-2.3.11/platforms/linuxIA64I64DPOpt/ lib/libmicocoss2.3.11.a(CosNaming.o): @gprel relocation against \dynamic symbol _marshaller__seq_CosNaming_Binding


Any help is appreicated, I anticipate having large simulations I would like to run parallel.

Thanks again,

David

I just wanted to write and say it seems all of the compilation warnings/problems were fixed when I installed a local version of gcc-4.1.1. Highly recommend doing this instead of using local compilers.

I am still having a problem with decomposePar, namely

undefined reference to `Foam::Cloud<foam::indexedparticle>::readFields()'

If anyone has any idea how to fix this, I would be interested.

Thanks again,

David

Hallo Henry,

I am investigating turbulent lean premixed high pressure
flames at stationary gas turbine conditions using your combustion model (unstrained laminar flame speed; solving for Xi transport) in RANS scenario. The combustion temperature is going beyond the adiabatic flame temperature to as high as 6000 K.
It would be helpful if you shed some light on this.

Best Regards,
Ramesh
