Hi: I wonder whether the error signal I got when trying to launch a computational procedure (molecular dynamics with software NAMD):
=========== TCL: Minimizing for 1000 steps ------------- Processor 6 Exiting: Caught Signal ------------ Signal: segmentation violation Suggestion: Try running with '++debug', or linking with '-memory paranoid'.

This error came with an otherwise efficien parallel UMA-type computer with four double-opterons. The same procedure run normally on a similar computer with two double-opterns. In both cases amd64 lenny. I did not know how to implement bthe suggestions "debug" '-memory paranoid' Thanks francesco pietra -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
