 Doing a ''make gen'' or ''make gen90'' will fail at the linking stage because it must be linked with the MPI linker, ''mpixlf77''. One needs to do

-There's no getting around the bug by switching compilers on the Q.
+Now, Alpgen creates its own ''asinh()'' function. Alternating versions of Fortran have an asinh() function or does not have it. The version installed on the BGP does not have it, so there is no conflict. However, the BGQ version has the ''asinh()'' defined so we need to replace every mention of ''asinh()'' in Alpgen to some unique name. In this case, we chose ''argsignh()''. Use this command:
-Replace asinh with argsinh whenever it appears:
+<code bash>
-  - alpgen.f
-  - zjet.f
-can use this command:
 find . -exec grep -l "asinh" {} \; | xargs -I GGGG sh -c 'sed "s/asinh/argsinh/g" GGGG > GGGG.tmp; mv GGGG.tmp GGGG'
