Hi Teresa, Thank you for your reply! I discussed this with Aditya and Rodrigo today about this. We will always have PGO turned 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. Thank you, Ruijie Ruijie Fang Email: r...

...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 t...

Hello Tobias, Thank you for the suggestion! Aditya also mentioned this. I will look into it.

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 e...

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).

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 workl...

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 latency characteristics of a VM...

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

...nable Partial Inliner by default Hello, I'd like to propose turning on the partial inliner (-enable-partial-inlining) by default.

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.

...ofile driven optimization except the profile is easier to gather: its the whole program timing. I imagine a "mega pass" could be written that tries all other passes in all their combinations to (eventually) arrive at the right set for a given program. There's one big issue with this: workload. Unlike profile-driven optimization, which can find parts of the program to optimize based on data collected from a run or several runs of the program, this evolutionary pass would need to run the exact same workload multiple times to discover which optimizations to apply. Obtaining a useful/typica...

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