Fwd: PPL Interface Issue

Dear Sir, I have used ppl 0.9 in my project, now I am upgrading it to ppl 1.1, during compilation I had ppl interface issue i.e. *shrink_bounding_box* and some other functions not found. I have commented all these functions and compiled my project successfully, now when I try to parse some file it returns me the following error: *terminate called after throwing an instance of 'std::out_of_range'* * what(): basic_string::substr* *Aborted* I want guidelines and will be glade to have you positive response. Best Regards, *Syed Sabah-ud-din Gilani*

Use of PPL in multithreade programs?
by giuseppe lipari 17 Apr '14

17 Apr '14

Dear all, is it possible to use the PPL in a multi-threaded program? We are writing a tool for real-time scheduling analysis, and we would like to parallelise the analysis. However, after a few naive tries, the program crashes unpredictably, so I suspect that maybe there is a problem in the library? Thanks in advance for your answer Giuseppe Lipari

Variable and Polyhedron dimension
by Stefan Schupp 05 Apr '14

05 Apr '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 I am starting to use the PPL for a project dealing with state set representations for hybrid systems. I have a question regarding the dimension of polyhedra and variables. From what I can conclude, each variable can be assigned to a coordinate axis. Suppose I utilize 4 variables with each assigned to a different dimension: Variable a(0); Variable b(1); Variable c(2); Variable d(3); When I construct a polytope with the first two variables, it has a dimension of 2, as intended. When creating the same polytope with other variables (e.g. c and d), I get a dimension > 2 (in this case 4). Is it intended to return the dimension of the variable assigned to the "latest/largest" coordinate axis, although the number of used variables/dimensions might be smaller than the returned value (the polytope still uses only 2 variables)?
