<font size=2 face="sans-serif">Hi there,</font>
<br>
<br><font size=2 face="sans-serif">I am using a parallel program written
in Fortran, which uses a dynamic storage allocation approach. The model
allocates data storage as needed based on numbers of several parameters
up to the maximum amount memory available on the computer being used. </font>
<br>
<br><font size=2 face="sans-serif">However, the parallel program gives
an error when allocating data arrays. If I change the parameters to reduce
the storages which data arrays need, the the parallel program has no problem.
</font>
<br>
<br><font size=2 face="sans-serif">I have a Windows 7 64-bit, Intel i7
2.4GHz, with 4.00 GB (3.88 GB usable) RAM. For large size data arrays,
I tested 2 to 8 processors (-np 2 or -np 8), none of them works. The error
is</font>
<br><font size=2 face="sans-serif">'forrtl: severe (41): insufficient virtual
memory'. The same size data arrays, if I do a none-parallel run, it works.</font>
<br>
<br><font size=2 face="sans-serif">I don't know what exactly MPICH2 did
when trying to allocate data arrays in each processor. Could you please
provide me any insights about it, or can you help me solve it?</font>
<br>
