[Einstein Toolkit] #428: Forbid configuration names ending in -reconfig
by Einstein Toolkit 12 Jan '15

#428: Forbid configuration names ending in -reconfig ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: Cactus | Version: Keywords: | ----------------------+----------------------------------------------------- I accidentally created a Cactus configuration with a name like "sim- reconfig". This confuses Cactus, because the command "make sim-reconfig" can then mean either to build the "sim-reconfig" configuration, or to reconfigure the "sim" configuration. Cactus should catch and forbid these cases. This is probably most cleanly handled by using a script instead of a Makefile to interpret the user commands. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/428> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

#1732: hw fails to link with cuda --------------------+------------------------------------------------------- Reporter: knarf | Owner: Type: defect | Status: new Priority: major | Milestone: Component: Other | Version: development version Keywords: | --------------------+------------------------------------------------------- I get link errors like this: {{{ /home/knarf/psamr/configs/sim/scratch/external/hwloc/lib/libhwloc.a (topology-cuda.o): In function `hwloc_cuda_backend_notify_new_object': /home/knarf/psamr/configs/sim/scratch/build/hwloc/hwloc-1.7.2/src /topology-cuda.c:122: undefined reference to `cudaGetDeviceProperties' /home/knarf/psamr/configs/sim/scratch/external/hwloc/lib/libhwloc.a (topology-cuda.o): In function `hwloc_cuda_query_devices': /home/knarf/psamr/configs/sim/scratch/build/hwloc/hwloc-1.7.2/src /topology-cuda.c:38: undefined reference to `cudaGetDeviceCount' /home/knarf/psamr/configs/sim/scratch/external/hwloc/lib/libhwloc.a (topology-cuda.o): In function `hwloc_cudart_get_device_pci_ids': /home/knarf/psamr/configs/sim/scratch/build/hwloc/hwloc-1.7.2/include/hwloc/cudart.h:49: undefined reference to `cudaGetDeviceProperties' collect2: error: ld returned 1 exit status }}} hwloc is built (system version present, but deemed too old). The configuration is using the standard debian option list (on spine). Everything is dev-version, clean checkout. It seems to me that hwloc picks up a cuda dependency (present on system), but the linker isn't told about it (no cuda present in Cactus config). -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1732> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit

[Einstein Toolkit] #1731: NaN in Dissipation/test_ah.par test case

#1731: NaN in Dissipation/test_ah.par test case ----------------------+----------------------------------------------------- Reporter: eschnett | Owner: Type: defect | Status: new Priority: unset | Milestone: Component: Other | Version: development version Keywords: | ----------------------+----------------------------------------------------- I see nans returned from the elliptic solver in the test case Dissipation/test_ah.par when I switch off optimization and enable debug information. Things are fine with optimization. I do not know where exactly the nans are generated; the input to the solver looks fine, the output does not. This is on OS X, with gcc 4.9.2. -- Ticket URL: <https://trac.einsteintoolkit.org/ticket/1731> Einstein Toolkit <http://einsteintoolkit.org> The Einstein Toolkit
