ABINIT Discussion Forums

The binaries available from ETSF.eu do not work. I'm running CentOS 5, 64bit. I've tried it on a Dell workstation with Intel Xeon processors. I try a sample file in the tutorial directory, abinit reads it, then exits with Illegal Instruction. Kernel log shows abinit crashed with invalid optcode. I saw this post about the same issue, but in windows. viewtopic.php?f=2&t=889&hilit=illegal

The binaries available from ETSF.eu work ... most of the time

The http://www.etsf.be/downloads/ETSF_softlib/Linux_binaries/abinit-6.4.3_gnu_core2.tar.bz2 package was built on a core2 system. But I just tested it on a

cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Xeon(R) CPU L5420 @ 2.50GHz

system (at least with v1t01 and paral/t_kpt+spin) ... no problemo AFAIK. And it should work with Intel gear back to 2006. Would you be so kind to check your CPU brand and to be more specific about the offending test(s).

Cheers,

There are 8 cores total. As for the file, I just ran one of the files in share/abinit/tutorial/Input. It was t1x.files and I get this:
/opt/abinit-6.8.1_x86_64_linux_gnu4.5/bin/abinit < t1x.files

Give name for formatted input file:

Give name for formatted output file:

This is from dmesg: abinit[26192] trap invalid opcode rip:17d1a3d rsp:7fffc77937f0 error:0

I also ran the two input files in share/example and get the same

hmmm ... at least missing sse4_1 compared to my core2 system - I assumed that 2007 "Xeon" labeled procs had all core2 features, I was wrong sorry . I'll prepare another binary less dependent on "new" cpu features.

Yup, only the latest cpus have SSE4 Check http://software.intel.com/en-us/article ... mizations/

I'm not sure if its listed, but to build abinit, CentOS 6 is needed. The version of gcc on CentOS 5 is too old. Might be nice to see that on the site.
