title: Are there threaded SPARQL implementations?
body: <p>We are building an iterative algorithm using a set of SPARQL queries for each iteration. This algorithm works great, but we're running into a CPU utilization issue. SPARQL engines like Fuseki are not truly multithreaded; they allow multiple simultaneous queries to be executed in multiple threads, but each individual query is single threaded. From looking at some Fuseki notes, I get the impression that Fuseki is not thread safe so this is not a trivial issue.</p>
  
  <p>Since our algorithm is inherently serial in terms of the SPARQL queries, and we are interested in one run at a time, is there some SPARQL engine that can take advantage of, say, 32 cores?</p>
