Ilegal instruccion on Xeon E5472

Hi all,

I'm compiling this tool called XIOS for parallel I/O operations, 

When i compile it with all its dependencies (HDF5, Netcdf) , and running the test, I get the following error:

forrtl: severe (168): Program Exception - illegal instruction

My operating system is Centos 6.6.  The login node in which I'm compiling its:  a 

Intel(R) Xeon(R) CPU           X5675  @ 3.07GHz

The compute nodes are: 

Intel(R) Xeon(R) CPU           E5472  @ 3.00GHz
flags		: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm dca sse4_1 lahf_lm dts tpr_shadow vnmi flexpriority

 

I'm compiling all the dependencies with the following directives:

-O3 -xSSE4.1 -fp-model source

I'd like to know if there is anything wrong with my setup , i'll appreciate it.

This code used to work with an older version of the intel compilers,

This is the file you should look at first.

Thanks for the reply,

I was able to run this code, by compiling all its dependencies with the following options:

-O3 -msse4.1  

The thing is that the login node has a newer processor than the compute nodes, and some of the flags are not available in the compute nodes.  Still there is something wrong numerically but i'm looking..

The only issue is that it is too old ISA and most computer systems support AVX and AVX2 ISAs. You could try these ISAs as well as soon as all problems / issues are resolved.
