How do parallel fuzzing corpus group-based strategy apply for ClusterFuzz?

[gtt1995]

I think this strategy is also good for clusterfuzz . google/fuzzbench#1197 (comment) https://www.fuzzbench.com/reports/experimental/2021-08-05-parallel/index.html Can this strategy be applied in the clusterfuzz? how do? Which files should modify? @jonathanmetzman Please help me !

Sorry for the atrociously late reply. Unfortunately I don't think it's so useful for ClusterFuzz. ClusterFuzz does parallelism by running many VMs not be running on many cores on one VM. In fact, ClusterFuzz's VMs only have one core.

Hello, I mean that bot can download some high-quality seeds from the bucket at server rather than download all seeds.  I think it's necessary to do some strategy?in the bucket rather than assign all the seeds to the bot. Each bot that fuzz the same target has the same initial corpus, although there are many random strategies within bots to avoid repeated task between bot, it is important to give mutation - based fuzzer a high-quality initial corpus. I don't know if I am making myself clear. Thanks for your time. mat
