[LLVMdev] Improving the usability of LNT
...pop-up to display the graph upon hovering over the workload url, instead of opening a new window. c. Next Steps: Split the results table into multiple sub-tables depending upon the suite (MultiSource/Applications, ...SingleSource/UnitTest) and make use of select-all checkbox and graph all the workloads in the corresponding suite. d. Next Steps: Add a Geomean button to plot the geomean of all the workloads instead of separate plots for each workload. If you feel that some of these improvements are valuable, then I can create patches and upload them in Phabricator for review. Thanks! With r...

Improve hot cold splitting to aggressively outline small blocks
...on for our benchmark, (i.e. we assume the profiling information is always available). In terms of the workload we supply to PGO: For postgresql, I suggested we use the "pgbench" benchmark, a TPC-B-based SQL benchmark for postgres, to supply profiling information for PGO. We can use other workloads/benchmarks should you have any other suggestions about this.

Improve hot cold splitting to aggressively outline small blocks
...splitting to aggressively outline small blocks." Over the course of last week, I met with my mentor and co-mentor, Aditya Kumar, and Rodrigo Rocha, and we made a preliminary plan on improving the existing hot/cold splitting pass in LLVM through identifying patterns of cold blocks in real-world workloads via block frequency information (We have settled to use the PostgreSQL codebase as a workload first, although if time permits, we will also target other large codebases). Our project will involve identifying new cold block patterns via static analysis in our workload, implementing detection of th...

virtio-user intarfece
Hello all i have multiple workload containers connected to my DPDK-app. I have another special container - which all packets are mirrored to it. Is it possible for zero-copy reason - that all virtio interfaces shared memory between my DPDK-app and workload containers - can be accessed by this special container ? it means that for every workload container X this is a shared memory between the:

XCP : workload load balancing with xen cloud platform ?
Hi, i''m reading the administrator guide of xcp, http://www.xen.org/files/XenCloud/reference.pdf, and it''s say that workload load balacing is possible (like citrix xenessiential). Could you tell me where i can download the install cd ? Alexandre Derumier Ingénieur Système Tél : 03.20.68.88.90 Fax : 03.20.68.90.81 45 Bd du général Leclercq 59100 Roubaix - France

C''mon ARC, stay small...
Running an mmap-intensive workload on ZFS on a X4500, Solaris 10 11/06 (update 3). All file IO is mmap(file), read memory segment, unmap, close. Tweaked the arc size down via mdb to 1GB. I used that value because c_min was also 1GB, and I was not sure if c_max could be larger than c_min....Anyway, I set c_max to 1GB. After a workload run....: > arc::print -tad { . . . ffffffffc02e29e8

determine the latency characteristics of a VM automatically
Hi George, Tow months ago, we talked about how to reduce the scheduling latency for a specific VM which runs a mixed workload, where the boost mechanism can not works well. I have tried some methods to reduce the scheduling latency for some assumed latency-sensitive VMs and got some progress on it. Now I hope to make it on demand. That is to say, I hope to get the scheduler to determine the

Fileserver performance tests
Hi all, i want to replace a bunch of Apple Xserves with Xraids and HFS+ (brr) by Sun x4200 with SAS-Jbods and ZFS. The application will be the Helios UB+ fileserver suite. I installed the latest Solaris 10 on a x4200 with 8gig of ram and two Sun SAS controllers, attached two sas-jbods with 8 SATA-HDDs each und created a zfs pool as a raid 10 by doing something like the following: [i]zpool create

[RFC] Enable Partial Inliner by default
...nable Partial Inliner by default Hello, I'd like to propose turning on the partial inliner (-enable-partial-inlining) by default. We've seen small gains on SPEC2006/2017 runtimes as well as lnt compile-times with a 2nd stage bootstrap of LLVM. We also saw positive gains on our internal workloads. ------------------------------------- Brief description of Partial Inlining ------------------------------------- A pass in opt that runs after the normal inlining pass. Looks for branches to a return block in the entry and immediate successor blocks of a function. If found, it outlines the res...

[LLVMdev] [Fwd: Optimization: Conclusions from Evolutionary Analysis]
I'm cross-posting the message below (from GCC list) because I believe it would (at some point) be very beneficial to build an evolutionary optimization pass into LLVM. The idea would be to discover the perfect set of optimizations for a given program by trying them all and analyzing the execution times of each. This would be somewhat like profile driven optimization except the profile is

The masked operations really shouldn't have any more latency. The time of the memory operation itself dominates. -David
