Fire Dynamics Simulator (fds5_osx_intel_64)
Compilation Date : Thu, 29 Nov 2007
Version : 5.0.2 Serial
SVN Revision No. : 1037
Operating System : Mac OS X 10.5.1 (9B18), Darwin 9.1.0
I tried the new 64-bit binary over the weekend using 3 variants of my input
file.
1) 2,764,800 cells (single mesh), still running (timestep 14500)
2) 1,382,400 cells (mesh1), 1,382,400 cells (mesh2), segmentation fault after
timestamp 1100
3) 777,600 cells (mesh1), 1,536,000 cells (mesh2), segmentation fault after
timestamp 900
For all cases, Activity Monitor showed 1 thread, ~2 GB real memory, ~5GB
virtual memory.

Fire Dynamics Simulator (fds_osx_intel)
Compilation Date : Wed, 05 Dec 2007
Version : 5.0.3 Serial
SVN Revision No. : 1068
The new 32 bit build, with the updated Intel compiler, appears to be working
for case
1 from above (time step 3800). I will need your help compiling MPI in order to
test
the 32 bit parallel build.

Please try the new 5.1.0 release, it includes both 32 and 64 bit versions.
I am not sure how well 64bit MPI version is working, please start a seperate
thread
if it does not work.

I would like to try the 32/64 bit MPI versions, although I am not entirely
clear how to do this on a multi-core
machine. Please advise.

I will put together a write up for this process and post it as a Wiki when it is
finished. I will also notify you through this issue posting.

A follow-up to Comment 7. I tried the new 32/64 bit 5.1.0 release using case 1
(see Comment 3) with the
following results.
Fire Dynamics Simulator (fds_osx_intel_32)
Compilation Date : Tue, 08 Jan 2008
Version : 5.1.0 Serial
SVN Revision No. : 1162
Time step 6979, 10s, successful
Fire Dynamics Simulator (fds_osx_intel_64)
Compilation Date : Tue, 08 Jan 2008
Version : 5.1.0 Serial
SVN Revision No. : 1162
Time step 600, 1.41s, error (174) segmentation fault
Not sure why the previous 64 bit build worked (see comment 3) and this one
didn't.

Have you tried the 5.1.1 version posted yesterday?
Please confirm that you get the Seg Fault with this one as well.

I got similar errors on my Linux-Workstation (2*QuadCore) with a self-compiled
version of fds (releases of 5.1.6 to present). As far as I now now, the compiler
options are the key to this error... I recompiled fds 5.2.1 with additional
options
and one case is running for much longer than ever.

Thank you for the tip... I am testing this flag out with the 64bit OS X builds
and
hopefully it will help there too.

Bryan and I worked on this issue Wednesday (10/22/08) from our homes using
iChat. He
guided me through the process of compiling OpenMP with the inclusion of
gfortran. We
still had more to do, but it was late so we stopped for the night. I noticed an
email
(home address) this morning that had an attachment which included the remaining
libraries and binaries necessary for 64 bit parallel fds. He said it worked for
him
using my input file with 4 meshes. I will try it out this weekend and report
back.

I am back again and will be looking into the newest errors.
John, can you post them here just to keep track for others who may encounter
this issue.
