 First of all, make sure your environment variables are set correctly
-to compile and execute a single process mpi applications for the SP2
-machine. They should be similar to the following:
-
-    setenv CC              mpcc_r
-    setenv MP_PROCS         1
-    setenv MP_NODES         1
-    setenv MP_LABELIO       no
-    setenv MP_RMPOOL        0
-    setenv RUNPARALLEL      "MP_PROCS=2 MP_TASKS_PER_NODE=2 poe"
+to compile and execute a single process mpi applications for the SP
+machine. Unfortunately, the setting varies from machine to machine.
+E.g., the following works for the Blue machine of LLNL.
+
+    setenv CC           mpcc_r
+    setenv F9X		mpxlf_r		# if parallel Fortran API is wanted
+    setenv MP_PROCS     1
+    setenv MP_NODES     1
+    setenv MP_LABELIO   no
+    setenv MP_RMPOOL    0
+    setenv RUNPARALLEL  "MP_PROCS=2 MP_TASKS_PER_NODE=2 poe"
     setenv LLNL_COMPILE_SINGLE_THREADED TRUE
 
 The shared library configuration for this version is broken. So, only
 static library is supported.
 
-An error for powerpc-ibm-aix4.3.2.0's (LLNL Blue) install method was

-from config/powerpc-ibm-aix4.3.2.0 before configuration:

+***Known problem***
+Some O2K system may encounter an error during make.
+    ld32: FATAL 9: I/O error (-lmpi): No such file or directory
+
+This is because libtool tries too hard to locate the loader 'ld'
+but ends up with one that does not know where to find the right
+version of libmpi.a for the particular ABI requested.
+The fix is to edit the file 'libtool' at the top of the build directory.
+Search for a string that looks like the following:
+    LD="/opt/MIPSpro/MIPSpro_default/opt/MIPSpro/bin/ld -n32"
+
+Replace it with something that knows how to find the right libmpi.a.
+E.g.,
