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).

...immediately instead of being requeued, and then makes %391 have a higher score than %253 causing it to be allocated before it. This works, but ends up causing an extra spill. * In RAGreedy::splitAroundRegion put global intervals into stage RS_Split immediately. This makes the chain of evictions after %396 not happen, but that gives us one extra spill and we still get one pair of copies in bb.17.switchdest13. * In RAGreedy::evictInterference put evicted registers into a new RS_Evicted stage, which is like RS_Assign but can't evict anything. This seemed to give OK res...

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)) { arc_buf_...

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

...D). 4) The virtual register for interval C is assigned to XMM9. 5) The virtual register for interval D is assigned to XMM0. At the boundary between A and C we have a copy from XMM8 to XMM9, and at the boundary between C and D we have a copy from XMM9 to XMM0. The spill is the result of several evictions. To assign interval D to XMM0 another virtual register was evicted. This virtual register had previously caused an eviction, which was subsequently spilled. *** Spill Weights The main question is why does the register allocator decide to split the constant live range and evict other non-remate...

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...

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

...16135 16 16119 pages in cache: 14533/8388608 (0.2%) [filesize=33554432.0K, pagesize=4K] In this case the file largely avoids being pulled into the page cache, and we do not evict useful stuff. Notice that the test takes slightly longer to run. This is expected because page cache eviction happens synchronously. I expect the cost when doing sequential writes to be higher. Linus outlined a technique to do this without the overhead, but unfortunately it is considerably more complex and dangerous than I am comfortable adding to the file plugin: http://lkml.iu.edu/hypermail/linux/kern...
