https://sourceforge.net/projects/brlcad/ brief overview


latest version as of 2018-02-05 is 7.26.4 (2017-10-15) available at https://sourceforge.net/projects/brlcad/files/BRL-CAD%20for%20Linux/

http://brlcad.org/wiki/Building_from_SVN current revision 70666
svn checkout https://svn.code.sf.net/p/brlcad/code/brlcad/trunk brlcad


dependances to compile on Mageia :
~- cmake
~- check pre-requisites (apparently not needed) : urpmi lib64xi6-static-devel lib64xext6-static-devel lib64x11_6-static-devel lib64xau6-static-devel lib64xdmcp6-static-devel

%%
mkdir brlcad-build
cd brlcad-build
cmake ../brlcad # takes 1 min 23 sec o_O quite fast

make # actual build 16h52 ETA +25 min hence 17h17 80% at 17h32... 90% at 17h36 95% at 17h40


make test # should report successful, Total Test time (real) = 182.33 sec
make benchmark # to test benchmark, may be better using option for cmake -DBRLCAD_FLAGS_OPTIMIZATION=ON

I'm compiling on my Asus Zenbook UX305 with 8 GB RAM & a CPU model name: Intel(R) Processor 5Y10 CPU @ 0.80GHz


Minimum run time is 3 minutes, 12 seconds
Maximum run time is 30 minutes
Estimated time is 9 minutes, 36 seconds


=== Benchmark ===
make benchmark result:

Benchmark results indicate an approximate VGR performance metric of 3679
Logarithmic VGR metric is 3.57 (natural logarithm is 8.21)
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#

These numbers seem to indicate that this machine is approximately 3679 times
faster than the reference machine being used for comparison, a VAX 11/780
running 4.3 BSD named VGR. These results are in fact approximately 3.57
orders of magnitude faster than the reference.

Here are some other approximated VGR results for perspective:
120 on a 200MHz R5000 running IRIX 6.5
250 on a 500 MHz Pentium III running RedHat 7.1
550 on a dual 450 MHz UltraSPARC II running SunOS 5.8
1000 on a dual 500 MHz G4 PowerPC running Mac OS X 10.2
1500 on a dual 1.66 GHz Athlon MP 2000+ running RedHat 7.3
52000 on a 4x4 CPU 2.93 GHz Xeon running RHEL Server 5.4
65000 on a 512 CPU 400 MHz R12000 Running IRIX 6.5

After cmake cmake ../brlcad -DBRLCAD_FLAGS_OPTIMIZATION=ON
not that much better:
