The problem below reproduce an issue that we have run into in production. We have a lot of ThreadLocal instances and quite a number of threads and we noticed very high latency for GC / CPU time spent collecting. The code below creates a ...

When a potentially leaking class is identified on the Zing Live Objects sub-tab, use the Memory tab to get information about the allocation site. The Memory tab contains allocation sites, which lead to allocation in a new thread local allocation buffer (TLAB) or allocation outside a TLAB, so...
the symmetric address that is returned by an NVSHMEM allocation routine is also a valid pointer to local GPU memory on the calling PE and can be used by that PE to directly access its portion of a symmetric allocation directly by using CUDA APIs and the load/store operations on the GPU. ...
If you are seeing an incomplete stack trace for a memory allocation, you may rerun the failing test with export ASAN_OPTIONS=abort_on_error=1:log_path=/tmp/asan:fast_unwind_on_malloc=0 To get core dumps of failures: export ASAN_OPTIONS=abort_on_error=1:disable_coredump=0 To see all...
