From 33f35183cbfdde70ee8f803acb5b735ad4dfe086 Mon Sep 17 00:00:00 2001 From: mainzer Date: Wed, 5 Aug 2020 15:39:49 -0500 Subject: When flushing, the metadata cache attempts to flush entries in increasing address order. To facilitate this, the metadata cache needs a list of of dirty entries in increasing address order. This is implemented via a skip list of all dirty entries in the cache. To date this skip list has been maintained at all times. However, profiling indicates that we can avoid significant overhead by constructing the skip list of dirty entries just before a flush, taking it down afterwareds, and not maintaining it during normal operation. This commit implements this optimization for both serial and parallel. Tested serial and parallel, debug and production on charis and jelly. --- src/H5AC.c | 483 ++++++++---- src/H5ACmpio.c | 42 +- src/H5ACprivate.h | 2 + src/H5C.c | 1684 ++++++++++++++++++++++++++++++++-------- src/H5Cdbg.c | 41 +- src/H5Cimage.c | 13 +- src/H5Cmpio.c | 391 ++++++---- src/H5Cpkg.h | 471 +++++++---- src/H5Cprivate.h | 5 +- src/H5Fint.c | 10 + test/cache.c | 2099 ++++++++++++++++++++++++++------------------------ test/cache_common.c | 171 +++- test/cache_common.h | 59 ++ test/cache_tagging.c | 13 +- test/ohdr.c | 24 + 15 files changed, 3651 insertions(+), 1857 deletions(-) diff --git a/src/H5AC.c b/src/H5AC.c index f8805b3..59cabde 100644 --- a/src/H5AC.c +++ b/src/H5AC.c @@ -136,14 +136,14 @@ static const H5AC_class_t *const H5AC_class_s[] = { /*------------------------------------------------------------------------- - * Function: H5AC_init + * Function: H5AC_init * - * Purpose: Initialize the interface from some other layer. + * Purpose: Initialize the interface from some other layer. * - * Return: Success: non-negative - * Failure: negative + * Return: Success: non-negative + * Failure: negative * - * Programmer: Quincey Koziol + * Programmer: Quincey Koziol * Saturday, January 18, 2003 * *------------------------------------------------------------------------- @@ -162,13 +162,13 @@ done: /*------------------------------------------------------------------------- - * Function H5AC__init_package + * Function: H5AC__init_package * - * Purpose: Initialize interface-specific information + * Purpose: Initialize interface-specific information * - * Return: Non-negative on success/Negative on failure + * Return: Non-negative on success/Negative on failure * - * Programmer: Quincey Koziol + * Programmer: Quincey Koziol * Thursday, July 18, 2002 * *------------------------------------------------------------------------- @@ -198,15 +198,15 @@ H5AC__init_package(void) /*------------------------------------------------------------------------- - * Function: H5AC_term_package + * Function: H5AC_term_package * - * Purpose: Terminate this interface. + * Purpose: Terminate this interface. * - * Return: Success: Positive if anything was done that might - * affect other interfaces;
