Hi

We were furnished with 2 Runtime keys for CPLEX. I am not sure which key is applicable for which situation>>>

Key 1:
LICENSE xxxxxxxxxxxxxxxx
RUNTIME CPLEX 11.000 never xxxxxxxxxx N any , options: m b q p=2 , license:xxxxxx

Key 2:
LICENSE xxxxxxxxxxxxxxxx
RUNTIME CPLEX 11.000 never xxxxxxxxxx N any , options: m b q use=MAX , license:xxxxxx

I am assuming (in the options) that m=mixed integer; b=barrier; q=quadratic. Can someone please explain what the "p=2" (in Key 1),  and "use=MAX" (in Key 2) are for, and under which circumstances do I use each? Thanks.

Regards
RAJ

Hi,

p is for Parallel CPLEX, p=2 is for 2 threads parallel solve (you can solve your model instance using a maximum of 2 threads in parallel). you can test parallel CPLEX 2 threads to see if it improves the perfs.

use is for the number of allowed [u]simultaneous[/u] solves (of different model instances) which is unlimited in key 2 (no parallel CPLEX option in this second key).
