thanks a lot for your help. This did help quite a lot.

Sorry about my dumb question, I did read the man page of opensm quite often 
already, but "--cache-options" and "OSM_CACHE_DIR" did activate my 
brain-internal filter to entirely skip this part of the man page ;)
Somehow I associated "cache" with "opensm-performance", but not at all with 
options...


Thanks again,
Bernd
