Dear Yong Wang,

MAXMEMORYUSAGE is an ADF keyword, not an environment variable. So you
need to specify it in the input file as described in the user's guide at
http://www.scm.com/Doc/Doc2004.01/ADFUsersGuide/page195.html

SCM_VECTORLENGTH sets the integration vector length which affect
performance and memory usage of ADF. Please also check
http://www.scm.com/Doc/Doc2004.01/ADFUsersGuide/page196.html on the
equivalent ADF input keyword.

SCM_IOBUFFERSIZE sets the size in megabytes of the I/O buffer for the KF
file system. You need to provide only a number without the Mb letters
after it. By the way, the same applies to the MAXMEMORYUSAGE keyword.

The format of the .machine file is MPI implementation-dependent. Since
you are using MPICH you need to separate host name and the process count
with a colon ":". Please check the MPICH documentation to be sure.

Best regards,
Alexei Yakovlev
SCM
