Thanks for your reply, Michael! Please see more details about my problem below: Let 'e' designate a system of boolean equations. Then I have the following code: I=ideal(e) G=I.groebner_basis() I2=ideal(G) V = I2.variety() 'e' is composed of approx. 1000 quadratic equations in approx. 500

Unfortunately not. I have seen Buchberger's algorithm implemented with parallel reduction on a shared memory system with allegedly decent performance with up to 8 CPUs in a shared memory system (i.e. all in one big box, not a cluster), but the implementation was in Java and is not integrated
