Dear David Parkhurst,
Taking into account the advice you told me in the last mail, I have been
checking the memories of several computers of the office to see when and
where my "complicated" input files worked properly.
I have tested the inputs in 7 computers for the moment. In four of them,
whose RAM memories were from 120 MB to 384 MB, the phast code begun the
calculations after the
processed database file
Then, they went more or less fast depending on their capabilities,
but the program run.
- Successfully processed chemistry data
In the other three computers, whose RAM memories range between 256MB and
1GB (this is the RAM memory of the computer for calculations), the
program failed after the previous message and said
The methodology used to
test the program was the same for each computer. We have some common
directories were the code to install and the input files were
- "ERROR: NULL pointer returned from malloc or realloc
- ERROR: Program terminating
- Forrtl: severe (157) Program exception - access
I installed the phast code in the computer, I copied the input files from
the common directory to the computer and finally I run the program.
The only difference we have observed between the computers is that the
four computers where the program run had WINDOWS 98 while the three
others had WINDOWS XP.
It seems clear that given the variability of RAM tested it can not be a
problem of RAM memory. It seems a problem related to WINDOWS XP.
Do you think that this is possible?
Any way, in this moment this situation is quite dangerous for us, because
we are changing the computers for new ones and these are coming with
WINDOWS XP, but at the same time we are interested in using PHAST. And it
will be very interesting to know if there is a solution or not.
As I told you in the last mail, we have no problems of this kind if we
simplify the model. But the question is why a more complicated model
works in one computer and not in another.
If you have a new idea to test or you need more information, please told
Thank you very much
