STP-Parti-Bitwuzla is a portfolio SMT solver based on STP (commit SHA 0510509) and Bitwuzla (v0.4.0).It participates in the Parallel Track and Cloud Track of QF_BV logic. STP-Parti-Bitwuzla comprises three primary components: the master, the partitioner, and the base solvers. The master is implemented by Python for task management and scheduling in distributed solving. We have customized STP to function as our partitioner, aiding in the partitioning of subproblems. Our tool does not restrict the choice of the base solver used in solving subtasks; it simply requires the executable binary file. For the SMT-COMP 2024, we have selected Bitwuzla as our base solver. STP-Parti-Bitwuzla is the practical implementations of our innovative concept of Variable-level Partitioning, which is applied to the Bit-Vectors theory. This technique is introduced for the first time in our recently published paper at CAV 2024, titled Distributed SMT Solving Based on Dynamic Variable-level Partitioning.
