enableAdvancedRASplitCost() does the same thing as ConsiderLocalIntervalCost, but as a subtarget option instead of a command-line option, and as I’ve said it doesn’t help because it’s a non-local interval causing the eviction chain (RAGreedy::splitCanCauseEvictionChain only considers the local interval for a single block, and it’s unclear to me how to make it handle a non-local interval).

Preamble -------- While working on an IR-level optimisation completely unrelated to register allocation I happened to trigger some really strange register allocator behaviour causing a large regression in bzip2 in spec2006. I've been trying to fix that regression before getting the optimisation patch committed, because I don't want to regress spec2006, but I'm basically fumbling in

Hi! We''ve started to poke and prod at Lustre 1.6.4.1, and it seems to mostly work (we haven''t had it OOPS on us yet like the earlier 1.6-versions did). However, we had this weird incident where an active client (it was copying 4GB files and running ls at the time) got evicted by the MDS and all OST''s. After a while logs indicate that it did recover the connection

Hi, Can a dbuf be in DB_CACHED state, db_holds == 0, b_efunc != NULL while its db_buf is put on the eviction list ? From an ASSERT in dbuf_do_evict(), it appears that it can. If it can, I am wondering what is preventing the following race dbuf_hold_impl() db = dbuf_find(dn, level, blkid); ... if (db->db_buf && refcount_is_zero(&db->db_holds)) {

Hi, I have also posted this on GitHub but it isn?t clear that was the right place: https://github.com/WayneD/rsync/issues/522 iCloud Drive will evict files that are unused or when additional space is needed on the local drive. The evicted files are replace by "bookmark" files that allow MacOS to continue to report the files in the file system as though they were actually present. The

So far the DRM GPUVA manager offers common infrastructure to track GPU VA allocations and mappings, generically connect GPU VA mappings to their backing buffers and perform more complex mapping operations on the GPU VA space. However, there are more design patterns commonly used by drivers, which can potentially be generalized in order to make the DRM GPUVA manager represent a basic GPU-VM

In short, we move out the low level content of a buffer object. In the case of textures and such this is utterly useless. Still it is accessed, because ttm sees no problem in using PL_SYSTEM or PL_TT memory. What is the best way to let ttm know we don't really appreciate that? A custom memory to evict to that cannot be mapped maybe. Or an extension of PL_SYSTEM or PL_TT. Share your ideas.

Currently, we take down the sgdma engine without evicting all buffers from VRAM. The TTM device release will try to evict anything in VRAM to GART memory, but this will fail since sgdma has already been taken down. This causes an infinite loop in kernel mode on module unload. It usually doesn't happen because there aren't any buffer on close. However, if the GPU is locked up, this

Should I be seeing messages like: Dec 14 12:06:59 nyx170 kernel: Lustre: MGS: haven''t heard from client dadccfac-8610-06e7-9c02-90e552694947 (at 141.212.30.185 at tcp) in 234 seconds. I think it''s dead, and I am evicting it. when the client was shut down cleanly? and the lustre file system is mounted via /etc/fstab ? The file system (i would hope) would be unmounted

on our cluster that has been running lustre for about 1 month. I have 1 MDT/MGS and 1 OSS with 2 OST''s. Our cluster uses all Gige and has about 608 nodes 1854 cores. We have allot of jobs that die, and/or go into high IO wait, strace shows processes stuck in fstat(). The big problem is (i think) I would like some feedback on it that of these 608 nodes 209 of them have in dmesg

Greeting All I have create a pool that consists oh a hard disk and a ssd as a cache zpool create hdd c11t0d0p3 zpool add hdd cache c8t0d0p0 - cache device I ran an OLTP bench mark to emulate a DMBS One I ran the benchmark, the pool started create the database file on the ssd cache device ??????????? can any one explain why this happening ? is not L2ARC is used to absorb the evicted data

Hi, While investigating a performance issue with an internal codebase I came across what looks to be poor register allocation. I have constructed a small(ish) reproducible which demonstrates the issue (see test.ll attached). I have spent some time going through the register allocator to understand what is happening. I have also experimented with some small changes to try and improve the

It is a bit unlcear to us why that's helping, but it does and unbreaks suspend/resume on a lot of GPUs without any known drawbacks.

The inode eviction can be very slow, because during eviction we tell the VFS to truncate all of the inode''s pages. This results in calls to btrfs_invalidatepage() which in turn does calls to lock_extent_bits() and clear_extent_bit(). These calls result in too many merges and splits of extent_state structures, which consume a lot of time and cpu when the inode has many pages. In some

The new cache=none mode is misleading since it does not avoid usage of the page cache. When using shared storage, we may get stale data from the page cache. When writing, we flush after every write which is inefficient and unneeded. Rename the cache modes to: - writeback - write complete when the system call returned, and the data was copied to the page cache. - writethrough - write completes

You can use these flags as described in the manual page to optimize access patterns, and to get better behaviour with the page cache in some scenarios. For my testing I used the cachedel and cachestats utilities written by Julius Plenz (https://github.com/Feh/nocache). I started with a 32 GB file of random data on a machine with about 32 GB of RAM. At the beginning of the test I evicted the
