x86 on ARM; Benchmark Results for Eltechs ExaGear Server

Eltechs ExaGear Server targets datacenters and cloud providers and enables them to further decrease TCO by running Intel software on power-efficient ARM-based servers. It is reliable, easy-to-use and fast.

But how fast is it? In order to find out we have performed a series of tests. The tests take at look at the overhead introduced running x86 applications through our translator technology and take a close look at the performance implications for CPU intensive workloads, IO and network intensives workloads.

Benchmark Description

For this benchmarking exercise, Eltechs ExaGear on Boston’s ARM-based Viridis servers, we have used GeoBenchmark freely available on http://geocomputing.narod.ru/benchmark.html. This benchmark evaluates a systems capability to perform data processing, and provides a good benchmark to stress both CPU in IO system capability. The benchmark was built for the ARM architecture and Intel 32-bit. Results of ARM-based (or native) tests were compared against Intel 32-bit tests started under Eltechs ExaGear Server.

For both sets of tests same Boston Viridis server was used.

Input and Output

These tests simulate processing modules with heavy disk input & output.

During those tests Eltechs ExaGear Server demonstrated exceptional performance of more than 90% out of native in average.

Multi-CPU

These tests are designed to estimate pure SMP performance and performance of SMP computers on the “memory access sensitive” algorithms. They show how good applications scale in multiprocessor and multithreaded environment.

Results clearly show that Eltechs ExaGear server is super scalable and does not impact parallelism of multi-threaded applications.

 

Conclusions

Eltechs ExaGear Server demonstrated excellent performance, in particular under heavy IO tests with nearly zero impact on performance while running Intel applications on ARM-based servers. This proves Exagear to be an excellent choice for running storage applications, disk and networking intensive tasks in translation mode on ARM servers today.

CPU intensive performance was around 50%. In future Eltechs expected to go as high as 80% out of native performance in average.

Scalability tests clearly showed that Eltechs ExaGear Server is highly scalable. It does not affect parallelism of applications and can be transparently used for respective software.

Taking in to consideration the ease of use, transparency for end users, and the immediate results – the Eltechs Exagear Server provides a real solution for the problem of migrating old legacy applications to ARM in the datacentre.

 

 

Centerton-based HP’s Moonshot “no match for Calxeda’s EnergyCore”

Following their recent review of the Boston Viridis, Anandtech have had their hands on HP’s new Moonshot ‘Microserver’ system based on Intel’s Centerton Atom CPUs and have drawn some interesting comparisons against the Calxeda architecture used in Viridis:

It is simple: even at 2 GHz, the Atom S1260 is no match for Calxeda’s EnergyCore at 1.4 GHz. The EnergyCore is the better server chip thanks to out of order execution, a 4 times larger L2-cache (4 MB) and the fact that it can offer 4 real cores.  Even if we assume that the 2 GHz Atom S1260 performs 8% better thanks to its higher clockspeed, it is no match for Calxeda’s EnergyCore.
