In the process of upgrading to the new code, I am getting a floating point exception error when I tried to run CellProfiler or CPCluster compiled under Matlab 2007a on a 64 bit Rocks cluster (centos-release.x86_64 6:4-4.3). The same CellProfiler code compiled under another linux box running fedora runs fine. From the matlab forum (link below), it appears that there are compatibility issues with matlab 2007a and the cluster in 64 bit mode.
As you are running your code on a cluster, what operating system have you tested this on? Should I be using the older or newer matlab compilers or resort to compiling Cellprofiler in 32 bit mode on the cluster as suggested by the matlab post?
