[LLVMdev] Seg faulting on vector ops
Hrm. This problem shouldn't be target specific. I am pretty sure prologue / epilogue inserter aligns stack correctly if there are stack objects with greater than default stack alignment requirement. Seems to be the initial alloca() instruction should specify 16 byte alignment? Evan On Jul 21, 2007, at 2:51 PM, Chris Lattner wrote: > On Fri, 20 Jul 2007, Chuck Rose III wrote:

[LLVMdev] Seg faulting on vector ops
I am fairly certain this is right. Chuck, can you do a quick experiment for me? Go back to your original code but make sure the alloca instruction specify 16-byte alignment. The code should work. If not, please file a bug. Thanks, Evan On Jul 24, 2007, at 1:58 PM, Evan Cheng wrote: > Hrm. This problem shouldn't be target specific. I am pretty sure > prologue / epilogue inserter

_Float16 support
I'd like to start a discussion about how clang supports _Float16 for target architectures that don't have direct support for 16-bit floating point arithmetic. The current clang language extensions documentation says, "If half-precision instructions are unavailable, values will be promoted to single-precision, similar to the semantics of __fp16 except that the results will be stored

[cfe-dev] _Float16 support
It seems that there are several issues here: 1. Should the front end be concerned with whether or not the IR that it is emitting can be translated into a well-defined IR? 2. How should the selection DAG handle data types whose representation isn't defined by the ABI we're targeting? 3. What should the ABI do with half-precision floats? Working backward... The third question here is

Thanks for the clarification. That behaviour is quite weird as arbiter bricks should hold?only metadata. What does the following show on host?uk3-prod-gfs-arb-01: du -h -x -d 1?/data/glusterfs/gv1/brick1/brickdu -h -x -d 1?/data/glusterfs/gv1/brick3/brickdu -h -x -d 1 /data/glusterfs/gv1/brick2/brick If indeed the shards are taking space -?that is a really strange situation.From which version

shadow_copy and glusterfs not working
Hello, we are trying to configure a CTDB-Cluster with Glusterfs. We are using Samba 4.5 together with gluster 3.9. We set up a lvm2 thin-provisioned volume to use gluster-snapshots. Then we configured the first share without using shadow_copy2 and everything was working fine. Then we added the shadow_copy2 parameters, when we did a "smbclient" we got the following message: root at

Hi, We're running a cluster with two data nodes and one arbiter, and have sharding enabled. We had an issue a while back where one of the server's crashed, we got the server back up and running and ensured that all healing entries cleared, and also increased the server spec (CPU/Mem) as this seemed to be the potential cause. Since then however, we've seen some strange behaviour,

Hi Liam, I saw that your XFS uses ?imaxpct=25? which for an arbiter brick is a little bit low. If you have free space on the bricks, increase the maxpct to a bigger value, like:xfs_growfs -m 80 /path/to/brickThat will set 80% of the Filesystem for inodes, which you can verify with df -i /brick/path (compare before and after).?This way?you won?t run out of inodes in the future. Of course, always

Hi Strahil, We're using gluster to act as a share for an application to temporarily process and store files, before they're then archived off over night. The issue we're seeing isn't with the inodes running out of space, but the actual disk space on the arb server running low. This is the df -h? output for the bricks on the arb server: /dev/sdd1 15G 12G 3.3G 79%

[LLVMdev] SSE intrinsic alignment bug?
Hi all, I think I might have found a potential bug when using SSE intrinsic and unaligned memory. Here's the code to reproduce it: #include "llvm/Module.h" #include "llvm/Intrinsics.h" #include "llvm/Instructions.h" #include "llvm/ModuleProvider.h" #include "llvm/ExecutionEngine/JIT.h" #include

Fwd: Troubleshooting glusterfs
Hello Nithya! Thank you so much, I think we are close to build a stable storage solution according to your recommendations. Here's our rebalance log - please don't pay attention to error messages after 9AM - this is when we manually destroyed volume to recreate it for further testing. Also all remove-brick operations you could see in the log were executed manually when recreating volume.

Hello Nithya! Thank you for your help on figuring this out! We changed our configuration and after having a successful test yesterday we have run into new issue today. The test including moderate read/write (~20-30 Mb/s) and scaling the storage was running about 3 hours and at some moment system got stuck: On the user level there are such errors when trying to work with filesystem: OSError:

self-heal trouble after changing arbiter brick
Hi Karthik, Thank you for your reply. The heal is still undergoing, as the /var/log/glusterfs/glustershd.log keeps growing, and there's a lot of pending entries in the heal info. The gluster version is 3.10.9 and 3.10.10 (the version update in progress). It doesn't have info summary [yet?], and the heal info is way too long to attach here. (It takes more than 20 minutes just to collect
