SPEC CPU2006 v1.2
SPEC CPU2006v1.2 measures compute intensive performance across the system using realistic benchmarks to rate real performance.
In our testing with SPEC CPU2006, we use the following basic commands to run these tests:
Runspec --tune=base --config=tweaktown.cfg, then int, or fp
To do multi-threaded, we add in --rate=64.
When SPEC CPU first came out, these tests could take up to a week to run, but as computers become faster, our tests now take up to four days for a full run, and even less on some systems.
The user can do many thing to effect the results of CPU2006 runs, such as compiler optimizations, add-ons like SmartHeap, and different commands used to start the tests.
This benchmark has many different commands to use depending on what the user is looking for. For our tests, we used basic commands that run a full test with a base tune.
You can see here the SPEC scores after full runs for Integer (int) and Floating Point (fp) tests.
Single-core runs show how fast (speed) a CPU can perform a given task. In the multi-core runs, we set SPEC CPU2006v1.2 to use all threads to measure the throughput of the system.
The additional cores/threads of this system have a huge impact on performance in these tests, and really show the amount of horsepower that a dual-socket system has over a single-socket board
Single-threaded results are still very important, but when you need many single-threaded apps to run, moving to a CPU with more cores is the way to go.
The X10DRC-T4+ really starts to shine in multi-threaded interger workloads.
Looking at the results of single-threaded integer runs, we can get an idea of speed at which the E5-2698 v3s can crunch through the different integer tests. Not all CPUs are equal here, and ones that have a higher speed will perform these tests faster. Naturally, using an overclocked system, or CPUs with a higher stock speed, will generate higher results.
Now we run the test using all 32 cores/64 threads cores on the E5-2698 v3 processors to measure the throughput of the system. In this test, more cores/threads will have a greater effect on the outcome.
The X10DRC-T4+ really takes off in this test. BIOS optimization for VM workloads clearly helps this out on multi-threaded tests.
Just like the integer tests, we now run the floating-point tests in single-threaded (speed) mode.
Here we see the results of the multi-core floating-point run that uses all 32 cores/64 threads cores on the E5-2698 v3 processors. Like the multi-threaded integer test, more cores/threads will have a greater impact on the test.
Similar to what we saw in the integer multi-threaded tests, the X10DRC-T4+ really takes off here.
