Hi,

    I have got a problem when using pnetcdf to output a large variable, and the error message is "Size of I/O request exceeds INT_MAX". I have tried the compiling option "--enable-large-req", but it does not work. Breaking the large variable into several parts and using "nf90mpi_iput_var" and "nf90mpi_wait_all" several times may solve this problem, but the code is inelegant. Is there a better way to deal with this problem?

    Thank you very much!

Zhuang
