'Monstrous Jesters' benchmark package
 

For a long time looking on tests I couldn't find some answers to some very basic (but/and important) aspects of CPU/RAM performance.
I am talking about sorting/decompressing/searching performed by console tools (written in C).
For example I have no opportunity to run my tests on some real powerhouse, this limits my quest of writing the fastest memmem (in C) function because i5/i7 have very different behavior (compared to Core 2) when comes to 1/2/4 bytes fetching. I mean already tuned functions for one CPU/RAM system are no longer superior on a newer system which demands intensive testing in order to retune them.

You all are welcome to use my latest benchmark (a NSIS installation) at:

'Monstrous Jesters' benchmark package short overview:

This is my latest 32bit/64bit (strstr-showdown included) CPU/RAM benchmark package (a NSIS installation).

File: Monstrous_Jesters.exe
Size: 153 MB (161,009,933 bytes)
Size unpacked: 500 MB
Size needed: 1200 MB

After installation 5 shortcuts (tests) are placed on Desktop/Programs.

All tests are written in C (sources included), and compiled with latest Intel 12.1 and Microsoft 16 optimizers.

The MEMMEM (strstr-showdown) takes some 21minutes to complete on Core2Duo_E7500_2.93Ghz.
Of course in order to obtain decent results stop all the concurrent processes before running the test.
Also enable 100% computing power.

Well, there are some additional tests (Intel 12.1 and Microsoft 16 executables included):
- lzpre a LZ77 32bit/64bit [de]compressor, written by Matt Mahoney;
- Yappy a LZ 32bit/64bit [de]compressor, written by IronPeter;
- Knight tour benchmark, finds first 9,000,000 tours (at rate some 1 billion per minute jumps), in fact tests/stresses only CPU clock;
- Quicksort 32bit/64bit used to sort 200,000,000+ pointers (pointing to 7bytes chunks).

Also I would be glad for some feedback and results on your machines.

Enjoy!

Cool I'll give it a shot on my x79

I rely on you Splave, take your time I have been waiting years so I am not in a hurry.
Feel free to ask whatever interests you.

I will take a look at it this week, if I like it I will toss it into my next review :)

Thank you Neuromancer.

Are you looking for SB and SB-E testing only, or would a 980x system be helpful as well?

No clue what all this means...or if I even did it correctly.

Are you looking for SB and SB-E testing only, or would a 980x system be helpful as well?

Wow, the three i7 systems will do perfectly, I am not pretentious as long as i7 is involved, nevertheless the latest Sandy-Bridge-E is gonna quench well the greediness in me.
I am very interested in how these super low memory latencies in SB are gonna affect my MEMMEM functions (stressing memory bandwidth along with physical RAM IOPS i.e. being latency bound).

A week ago I saw a 5GHz SB with 22GB/s Memory Read bandwidth, my miserable/old laptop gives 5GB/s whereas my MEMMEM functions work at 3-4GB/s do the math how close are they to the limit. Therefore the thing that would make my eyes happy is a machine with High Performance CPU-RAM bus maybe triple channel is the answer (the above mentioned 22GB/s were achieved with i7 2700K @ 4.9GHz (1.420V) 24/7 Max 69C; 4 x 4GB Samsung Extreme Low Voltage 1866MHz @ 8-9-9-24-1T at 1.5V's).

Just uploaded revision B of 'Monstrous Jesters' - a new multi-threaded (up to 48 threads stressing RAM/Cores) test was added.

Thank you MaadDaawg for your readiness to help me.

Thanks a lot rickss69, I will explain but please give me some specs of your machine.

Last night I run the new Revision B on my T7500 2200MHz dual channel DDR2 667MHz:

Looking at Knight Tours test your/my results are: 90s/218s, let me guess here your CPU runs at 218/90*2200MHz = 5328MHz or I am wrong?

Results for 'Monstrous Jesters' revision B on my laptop T7500 2200MHz (4MB L2 cache) 4GB dual channel DDR2 667MHz using Windows 7 64bit:

Hope the above results are a good (but poor in the same time) starting point to feel how Core 2 lags behind compared to new architectures.

My runs were with the gamer which has no overclock atm (2600K).
