+Subject: [PATCH] fix: ensure that LAPACK RNG state is propagated
+
+ - fixes #401, #410, #411
+ - restores 'inits' variable removed in ce2e69a849da1d10dad5d6d3ec4db6120b3ecf50, ensuring that the RNG state is propagated
+ - reverts e0d67054f573da351f12a226f7c7cc65a690ef3d to ensure that seed is different on each parallel thread
+ - updates seed initialization of parallel pdgetv0/psgetv0 so that they match that of pzgetv0/pcgetv0
