benchmarking

问题 Can someone help me how can I run in Crypto++ benchmarks test? I have to make some tests. I found Crypto++ but I don't know how use benchmarks test in Crypto++. I also want to run them after installing the library. Thanks for help. 回答1: Can someone help me how can I run in Crypto++ benchmarks test? $ cd cryptopp-src $ make static cryptest.exe $ ./cryptest.exe b 3 2.76566 > benchmarks.html cryptest.exe takes three arguments: (1) b for benchmarks, (2) time for the length of each test, in

问题 I am Performing YCSB bench marking on Redis cluster. I have created redis cluster and its working with the following condition. If I specify to enable cluster mode in redis client with -c parameter. The chunks are moved correctly. ./redis-cli -h -c "host ip" -p "port" if I dont specify -c parameter, it moved the chunk with error ./redis-cli -h "host ip" -p "port" SO in YCSB load option, I don't know how to enable the cluster option ( -c parameter). Currently I am using the following conmmand

问题 A full SUPERCOP benchmark is done as follows: wget https://bench.cr.yp.to/supercop/supercop-20170228.tar.xz unxz < supercop-20170228.tar.xz | tar -xf - cd supercop-20170228 nohup sh do & But it takes too much time to run every cryptographic algorithm benchmark. I wondered, if you know how to benchmark only Ed25519 in SUPERCOP, without benchmarking all the other algorithms. Ed25519 is in the crypto_sign/ed25519 folder of SUPERCOP. 回答1: The SUPERCOP tips page (https://bench.cr.yp.to/tips.html)

问题 I am trying to build NAS benchmarks using Intel MPI and below is the makefile that I am using. #--------------------------------------------------------------------------- # # SITE- AND/OR PLATFORM-SPECIFIC DEFINITIONS. # #--------------------------------------------------------------------------- #--------------------------------------------------------------------------- # Items in this file will need to be changed for each platform. #--------------------------------------------------------

问题 One of the commonly (?) used DBMS benchmarks is called SSB, the Star-Schema Benchmark. To run it, you need to generate your schema, i.e. your tables with the data in them. Well, there's a generator program you can find in all sorts of places (on github): https://github.com/rxin/ssb-dbgen https://code.google.com/p/gpudb/source/checkout (then under tests/ssb/dbgen or something) https://github.com/electrum/ssb-dbgen/ and possibly elsewhere. I'm not sure those all have exactly the same code, but

问题 i have read articles that say: using the prototype will be fastest since functions declared are shared. more detail was explained in this article where tapping JS native prototype will increase performance as compared to using 'improvisions'. closures should perform worse since each creation of it returns a separate copy of a set of functions and variables. objects (functions) are sort of closures but with this . has access control (public/private). they're supposed to be better than closures

问题 I followed few suggestions available online but none has helped. Got caliper and built it from https://github.com/peterlynch/caliper export CLASSPATH=/home/deepakkv/projects/poc/benchmarkparquet/target/classes:~/.m2/repository/com/google/code/caliper/caliper/1.0-SNAPSHOT/caliper-1.0-SNAPSHOT.jar:~/projects/poc/caliper/lib/gson.jar:~/projects/poc/caliper/lib/allocation.jar:~/projects/poc/caliper/lib/guava-r09.jar Now to push the results to web, we need to specify the key. Here is the confusion

问题 I'm using make --jobs=<num> to do parallel builds on a multi-core machine. I want to have a robust method to record how long it takes for a given target to get built using the pre-action, build, post-action model. This answer says: Also, start and end times are not all there is to know about how long an action takes, when you are running things in parallel; rule A might take longer that rule B, simply because rule B is running alone while rule A is sharing the processor with rules C through J

问题 My new PC has a Core i7 CPU and I am running my benchmarks, including newer versions that use AVX instructions. I have installed Visual Studio 2013 to use a newer compiler, as my last one could not fully compile for full SSE SIMD operation. Below is some code used in one of my benchmarks (MPMFLOPS), and compile and link commands used. Tests were run with the first command to use SSE instructions. When xtra is 16 or less, the benchmark produces 24.4 GFLOPS. CPU runs at 3.9 GHz, so result is

问题 I am working on a site at the moment, and there is a concentrated focus on efficiency and speed in loading, processing and such like. I'm using the mysqli extension to get my database bits and bobs, but I'm wondering what's the best / most efficient way of outputting my dataset? At the moment I'm using $mysqli->fetch_assoc() and a foreach(). Having read http://www.phpbench.com I know that counting my data first makes a difference. (I'm going to optimise after build) My question is, which is
