 ====== NIMROD 2022 ======
 The method for getting NIMROD running at NERSC has changed slightly as the default version of some modules on NERSC have changed. This wiki will give instructions to help set up the most recent version of nimdevel and include some tips to help compile older versions of NIMROD. This page  will run through the steps necessary to compile the code at NERSC.

 Now that the necessary modules have been loaded the code can be compiled. There are two main methods of doing this at NERSC. The first is to use the mknimall.sh script provided if nimall is checked out. Alternatively, Jake's config scripts may be used to build the code on Cori.

 ===== Compiling older versions at NERSC =====
+Some older versions of Nimrod ( such as 3.2.4) may contain a README that instructs the user to compile the code slightly differently . When following these instructions the user may run into some errors when compiling. One common issue is getting a type mismatch error when calling the mpi_bcast routine. This is due to these version of nimrod being created and compiled using an older version of gcc. To fix this issue, add the fortran compile flag:
+<code>
+-fallow-argument-mismatch
+</code>
+If using cmake to compile, this can be done by adding the following line into the CMakeLists.txt file:
+  set(CMAKE_Fortran_FLAGS "-fallow-argument-mismatch ${CMAKE_Fortran_FLAGS}")
