Migshm consistency

Hi there,

I am playing around with the migshm-patch: I wrote a c++ program that does  
a big matrix-multiplication, where the result is written into a shared  
memory region by child processes. On a single machine, the program works  
just fine, wheras on the cluster when I read out the shared memory, I get  
only a parts of the result.

Is it possible, that the memory is not flushed back after a semop()? To  
make sure I don't miss anything there, I copied the semop() calls from the  
shm_test.c example in the testing suite. --> Without success... Then I  
looked for the flush() system call (mentioned here:  
http://opensource.codito.com/migshm/assumptions.php) but wasn't able to  
figure out, where it is defined. Does someone know it?

I'm using migshm-2.4.26-2.

Thanks,
Adrian
