[gate-users] results differing

[Emma Lewis]

Hello,

I have built Gate on 2 different linux systems, with the following
configs:

Suse linux 9.3
gcc 3.3.5
clhep 1.8.2.1
geant 4.7.1
gate 1.2

and

Redhat linux 7.2
gcc 3.4.2
clhep 1.8.2.1
geant 4.7.1
gate 1.2

When I run the SPECT benchmark on the 2 systems, using the same initial
random seed, I get very slightly different results: the singles output
file are identical except for an additional 2 singles for the Suse
build.

I'd appreciate any ideas why this might happen

cheers
Emma
