Hi guys,
All the OpenCL workunits (Einstein@Home) I've tried have stopped prematurely, and looking at the event log, I notice that for all of them, it says the output file was absent. What does this mean? Here is all of my information:

CPU Intel Core i7 4750HQ
Northbridge Intel Crystalwell rev. 08
Southbridge Intel ID8C4B rev. 05
Memory Type DDR3

Microsoft Windows 7 (6.1) Ultimate Edition 64-bit Service Pack 1 (Build 7601)
Driver Version 10.18.10.3345
OpenCL version 1.2

Here's the output when I restart BOINC:

Hi guys,
All the OpenCL workunits (Einstein@Home) I've tried have stopped prematurely, and looking at the event log, I notice that for all of them, it says the output file was absent. What does this mean? Here is all of my information:

1/7/2014 10:33:31 PM | | OpenCL: Intel GPU 0: Intel(R) Iris(TM) Pro Graphics 5200 (driver version 10.18.10.3345, device version OpenCL 1.2, 1624MB, 1624MB available, 352 GFLOPS peak)

'Output file absent' means that the application crashed before it completed its work, so there are no results to send back to the project.

Since it's an Einstein problem, please report it on the Einstein message boards - specifically in the thread Errors running Einstein@home on Intel 4000 graphics: you'll see that other people have been having problems with that 10.18.10.3345 driver.

I don't know whether any earlier driver, like the 9.18.10.3071 that works for 4xxx series GPUs, is available for your 5200: if not, knowing that there are chips out there which can't currently be used might spur the project into researching what the problem is more quickly.

This subject came up again in a related discussion at another message board.

Prompted me to look and see what was available:

https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=23106&lang=eng&OSVersion=Windows%207%20(64-bit)*&DownloadType=Drivers

says that it installs driver 9.18.10.3257 for Intel® IrisTM Pro graphics 5200 running Windows 7* and Windows 8* 64 - that sounds like the right combination for Einstein and your setup.

Hi, thanks for the help. I downgraded the driver to the version you mentioned, and everything is fine now.
