Our aim<br /> is to allow programs expressed in a style as close to mathematical notation as<br /> possible, to effectively use multicore parallelism, for large values of &quot;multi&quot;.<br /> <br /> Challenges in the mapping to the JVM include:<br /> * thread model mismatch (Fortress depends on workstealing)<br /> * type system mismatch (Fortress does not erase its types)<br /> * dispatch mismatch (it's multiple; we think we will compile this into visitors or decision trees as appropriate)<br /> * transactions (nested and executed by multiple threads)<br /> * value objects (return values, in arrays)<br /> * clean mapping to legacy (FORTRAN) libraries<br /> * access to FP ops carried out in different rounding modes.<br /> * proper tail call elimination, perhaps?<br /> <br /> http://wiki.jvmlangsummit.com/pdf/16_Chase_fortress.pdf<br /> <br /> === Author Bio ===<br /> <br /> === Key Issues for Discussion (cooperative) ===<br /> ''(please expand cooperatively)''<br /> [[Talk:Fortress]]</div>
