Use open2 in cluster

[zhuangdvm]

Dear friends,
I am trying to activate a Fortran program in a high performance cluter. The IO of the Fortran program is accomplished by a PERL script, which uses various PERL intrinsic functions and plug-in C functions to do IO jobs. I notice that the PERL program get stuck when it use open2 function to start the communication with the fortran program. In local linux PC, there is not such problem and the program can work properly. Does there anybody have insights about this? Thanks!
Zhong

I assume you mean IPC::Open2, try using IPC::Open3 instead which is said to have better error handling. Make sure to read the documentation well as it might give you a clue why your application is getting stuck.
