Problem with Sample CT scan simulation with a voxelized human phantom. #18

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Hallo,

I have installed debain wheezy 7.0. I would like run  the SAMPLE SIMULATION FOR 
MC-GPU v1.3 USING THE ZUBAL PHANTOM. The voxelizied geometery of the Zubal 
phatnow has been downloaded from the adress http://noodle.med.yale.edu/zubal/.

 The MCGPU was obtained with the command:
 gcc -O3 zubal2mcgpu.c -o zubal2mcgpu.x 

The exceution of the next command showed an error  Memory access erorr

./zubal2mcgpu.x zubal2mcgpu_conversion_table.in voxel_man.dat

The used System for the MCGPU has the following specfications:  

-Processor

Intel® Pentium® 4 Processor 641   • 3.20 GHz, 2 MB L2 cache, 800 MHz front 
side bus 

- Standard memory 

512 MB (256 MB x 2)

- Graphic Subsystem Video Card Memory

Graphics memory is shared with system memory. Graphics memory usage can vary 
from 8 to 128 MB depending on the amount of system memory installed and system 
load

Thank you

Regards 
Ghassan

Hi Ghassan,

I can not tell what is wrong with the program with this amount of information 
but if your computer really has only 512 MB of memory it may be easily be 
running out of memory. Try to compile it with the command line with all 
programs and the windows manager turned off to save memory. I have never tested 
the code with a computer with less than 4 GByte of RAM.
