Is Open CL compatible with Xeon E5345 or E5620

[hazardsmusc_edu]

Hi Folks,

I am very new (as I got an email this morning mentioning OpenCL) to OpenCL. I have a small research cluster with has

Dual quadcore Xeon E5345 or E5620 processors.

Can OpenCL work with these older Xeons?

Thanks

Hi, Intel OpenCL CPU runtime requires SSE4.2 instriction set. I see that Xeon E5620 http://ark.intel.com/products/47925 supports it, so yes, you should be able to develop and run OpenCL applications on these systems. I'm not sure about Xeon E5345 - you may try to run (assuming Linux) 'cat /proc/cpuinfo | grep sse4_2' command to check the presence of the corresponding flag. Thanks, Yuri
