[Radiance-general] rcontrib malloc error

[Galen Burrell]

I'm running view matrix calculations using rfluxmtx/rcontrib for the 3-phase method and keep getting one of two errors:

1)
rcontrib(2346) malloc: *** mmap(size=a really big number) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
rcontrib: system - out of memory in samp_hemi: Cannot allocate memory
rcontrib: system - read error from render process
Killed: 9

2)
rcontrib: system - read error from render process
Killed: 9

I can't establish a pattern for why/when these two errors occur.

Oddly, I don't always get the error with some gridpoint files (with 5900 points), but I consistently get it with another gridpoint file (with 7500 points).  I don't understand why grid size would influence memory though...?

System is Mac OS 10.7.5 (2 x 6-core); error repeats on my laptop with Yosemite installed
Latest Radiance HEAD release; although the error repeats on older versions from 6 months ago
rcontrib settings are: -n 12 -ab 12 -ad 100000 -lw 1e-5 -I+

Any clues on why I'm getting these errors?

Thank you!

Galen
