[Bug other/58996] [4.9 regression] build failure in libcilkrts
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58996 Barry Tannenbaum changed: What|Removed |Added CC||barry.m.tannenbaum at intel dot co ||m --- Comment #6 from Barry Tannenbaum --- Hi. I'm one of the Cilk runtime developers. Balaji asked me to help him with this since it's a Cilk runtime issue. I don't understand the reluctance to check the defintion of __cpu_set_t_defined, since it's defined right there in /usr/include/bits/sched.h on my Ubuntu system. Is the problem that it's not a "top-level" include file? How about if I check the macros defined in /usr/include/sched.h. I could easily check for a defintion of CPU_SETSIZE, for example. - Barry
[Bug other/58996] [4.9 regression] build failure in libcilkrts
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58996 --- Comment #14 from Barry Tannenbaum --- The original author of the code is no longer working on the Cilk project, so I can't say why it's using sched_getaffinity + gettid instead the pthread routine. But I'll modify it to use the pthread routine and investigate support for >1024 cores. Is there a machine we can use to test that? - Barry
[Bug c++/63147] New: Cilk Plus in GCC 4.9 is missing metadata support
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63147 Bug ID: 63147 Summary: Cilk Plus in GCC 4.9 is missing metadata support Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: barry.m.tannenbaum at intel dot com The Cilk Plus implementation in GCC C/C++ is missing support for the metadata annotations defined in "Intrinsics for Low Overhead Tool Annotations V1.0." available from http://www.cilkplus.org/download#open-specification . These are required to allow the Cilkscreen race detector, Cilkview scalability analyzer and Cilkprof parallelism analyzer to work. Intel Inspector also uses the metadata.
