If you grab the latest master, the computation parallelism can be set by the parameter compiler.parallelism: -- 0, the default, means to use the storage parallelism as computation parallelism -- negative value, means to use all available cores in the cluster -- positive value, means to that number of cores, but it will fall to back to use all available cores if the number is too large.

(Where you'd specify storage parallelism based on drives, and compute parallelism based on cores, both spread across all of the cluster's resources.)

I have reset the AsterixDB and retestAsterixDBusing new environment on 100G, 10G. The efficiency for all the tests(goodand bad order) have been all improved to twice speed. I will finish all the tests and update the result later. Bests, Mingda On Tue, Dec 20, 2016 at 10:20 PM, Yingyi Bu <[email protected]>wrote: Hi Mingda,I think that in your setting, a better configuration forAsterixDBmight be to use 64 partitions, i.e., 4 cores *16.1. To achieve that, you have to have 4 iodevices on each NC,e.g.:iodevices=/home/clash/asterixStorage/asterixdb5/red16--> iodevices=/home/clash/asterixStorage/asterixdb5/red16-1, iodevices=/home/clash/asterixStorage/asterixdb5/red16-2, iodevices=/home/clash/asterixStorage/asterixdb5/red16-3, iodevices=/home/clash/asterixStorage/asterixdb5/red16-4 2. Assume you have 64 partitions, 31.01G/64 ~= 0.5G. That meansyou'dbetter have 512MB memory budget for each joiner so as to make thejoinmemory-resident.To achieve that, in the cc section in the cc.conf, youcouldadd:compiler.joinmemory=536870912 3. For the JVM setting, 1024MB is too small for the NC. In the shared NC section in cc.conf, you can add: jvm.args=-Xmx16G 4. For Pig and Hive, you can set the maximum mapper/reducernumbers inthe MapReduce configuration, e.g., at most 4 mappers per machine andatmost 4 reducers per machine.5. I'm not super-familiar with hyper threading, but it might beworthtrying 8 partitions per machine, i.e., 128 partitions in total. To validate if the new settings work, you can go to theadmin/clusterpage to double check. Pls keep us updated and let us know if you run into any issue. Thanks!
