+==== Amber22 ====
+Amber22 is somehow incompatible with CentOS/Rocky openmpi (yum install). Hence the latest version of openmpi was compiled and installed into $AMBERHOME. No need to set PATHs, just be sure to source amber.sh in your script. (compile instructions below for me...)
+https://ambermd.org/InstCentOS.php\\
+"download a recent version of OpenMPI at open-mpi.org, untar the distribution in amber22_src/AmberTools/src, and execute in that directory the configure_openmpi script. (Do this after you have done a serial install, and have sourced the amber.sh script in the installation folder to create an AMBERHOME)"
+<code>
+[hmeij@n79 src]$ echo $AMBERHOME
+/share/apps/CENTOS7/amber/amber22
+[hmeij@n79 src]$ which mpirun mpicc
+/share/apps/CENTOS7/amber/amber22/bin/mpirun
+/share/apps/CENTOS7/amber/amber22/bin/mpicc
+</code>
+First establish a successful run with the **run.rocky** script for Amber20 (listed above). Then change the module in your script. (for queues amber128 [n78] and test [n100-n101] for gpus and mw128 and tinymem for cpus)
+<code>
+module load amber/22
+# if the module does not show up in the output of your console
+module avail
+# treat your module cache as out of date
+module --ignore_cache avail
+</code>
+First establish a success full run with the **run.centos** script for Amber20 (listed above, for cpus or gpus on queues mwgpu and exx96).
+Then edit the  script and apply these edits. We had to use a specific compatible ''gcc/g++'' version to make this work. Hardware is getting too old.
+<code>
+# comment out the 2 export lines pointing to openmpi
+##export PATH=/share/apps/CENTOS7/openmpi/4.0.4/bin:$PATH
+##export LD_LIBRARY_PATH=/share/apps/CENTOS7/openmpi/4.0.4/lib:$LD_LIBRARY_PATH
+# additional gcc 6.5.0
+export PATH=/share/apps/CENTOS7/gcc/6.5.0/bin:$PATH

+# edit or add correct source line, which and ldd lines just for debugging
+###source /usr/local/amber16/amber.sh # works on mwgpu
