[Darshan-users] Recording more than 1024 files

Hi George,

Unfortunately it is hardcoded for the moment (see 
DARSHAN_DEF_MOD_REC_COUNT) regardless of how much total memory in bytes 
you allow each module to use.  We are working to have that tunable in an 
upcoming release.

Another option, depending on your use case, may be to configure Darshan 
to exclude some directories so that it doesn't use up entries on files 
that you aren't interested in.  There is some info about that option in 
this mailing list post:
