[Hpc-forum] Floating point exception

[Tamas Hegedus]

Sziasztok!

Egy szimulációm nem fut le, indulás után az alábbi hibát dobja.
Az elmúlt évben sok ilyen szimulációt futtattam.
Ha azt a szimulációt futtatom, ami a múlt héten probléma nélkül 
lefutott, akkor is ezt a hibát kapom.

A program openmpi_gcc-1.4.3 párhuzamos könyvtárat használ.

Valaki látott már hasonlót? Van valakinek valami ötlete, hogy mi lehet a 
probléma?

Nagyon köszönöm előre is!
Üdv,
Tamás
