Dear All,

We have compiled CAM2 on different systems. Now we have just succeeded building 
it on IA32 linux with Portland Group compilers. And we use a PSB job script to 
submit the job. We received such information at the end of cam.out,

I am not sure whether this is caused by the ice model or by the inadequate 
memory on IA32. We have built and run the CAM2 on AMD(linux), SGI with no 
problem. But the model was compiled using Lahey compiler on those systems. 
Anyone there can help me figure this out? Thanks for any help in advance.


Best regards,
