[SYCL] Reduce memory size to reduce test complexity and avoid flaky memory related issues

[asudarsa]

This testcase is used to test whether compute and copy commands are handled correctly in an expected way. Size of memory is not important for this test. However, existing testcase makes unnecessary use of large array sizes. This could have been the cause behind some of the flaky test failures seen in testing. This change reduces the memory size and should help to avoid any memory related failures.

LGTM.

Reduce memory size to reduce test complexity

I agree with that part.

and avoid flaky memory related issues

I don't understand the rootcause of "flaky memory related issues" to agree with the second part. @asudarsa, please, share more details on what is causing these issues if you have them.

Hi @bader
I am not able to reproduce this failure locally (tried a lot of permutations). My hypothesis s that the 'high' memory requirements of this test s the root cause for the failure of this test in a CI environment. We can look for other possible causes if we see this fail after this change. Thanks

Did you try testing this hypothesis by increasing memory requirements in this test?
It should help to expose the issue frequent enough for reproducing and debugging.
