small fixes to darshan-runtime documentation

parent 52a56762
......@@ -20,6 +20,10 @@ information about HDF5 and PnetCDF access. Darshan also exposes an API that
can be used to develop and add new instrumentation modules (for other I/O library
interfaces or to gather system-specific data, for instance), as detailed in
http://www.mcs.anl.gov/research/projects/darshan/docs/darshan-modularization.html[this document].
Newly contributed modules include a module for gathering system-specific parameters
for jobs running on BG/Q systems, a module for gathering Lustre striping data for
files on Lustre file systems, and a module for instrumenting stdio (i.e., stream I/O
functions like `fopen()`, `fread()`, etc).
This document provides generic installation instructions, but "recipes" for
several common HPC systems are provided at the end of the document as well.
......@@ -531,7 +535,7 @@ behavior at runtime:
* DARSHAN_LOGPATH: specifies the path to write Darshan log files to. Note that this directory needs to be formatted using the darshan-mk-log-dirs script.
* DARSHAN_LOGFILE: specifies the path (directory + Darshan log file name) to write the output Darshan log to. This overrides the default Darshan behavior of automatically generating a log file name and adding it to a log file directory formatted using darshan-mk-log-dirs script.
* DARSHAN_MODMEM: specifies the maximum amount of memory (in MiB) Darshan instrumentation modules can collectively consume at runtime (if not specified, Darshan uses a default quota of 2 MiB).
* DARSHAN_MMAP_LOGPATH: if Darshan's mmap log file mechanism is enabled, this variable specifies what path the mmap log files should be stored in (if not specified, log files will be stored in `/tmp`.
* DARSHAN_MMAP_LOGPATH: if Darshan's mmap log file mechanism is enabled, this variable specifies what path the mmap log files should be stored in (if not specified, log files will be stored in `/tmp`).
