[Pw_forum] Errors in test-suite qe-6.0 and qe-6.1 how bad ?

[Thibaut VERY]

Hello,

I installed qe-6.0 and 6.1 on an IBM machine using power8 cores.
The binaries are linked to ESSL.

When running the test-suite, I got errors that are almost the same for both versions.
Some seems reasonable but other much less.
The tests are done in parallel with 4 MPI tasks by setting the variable QE_USE_MPI=1.
Here are some examples:
cp_h2o - h2o-mt-blyp-1.in: **FAILED**.
s1
    ERROR: absolute error 4.99e-04 greater than 1.00e-05. (Test: -0.46198575.  Benchmark: -0.46148672.)
cp_h2o - h2o-mt-blyp-4.in: **FAILED**.
t1
    ERROR: absolute error 1.92e-03 greater than 1.00e-05. (Test: 43.78585.  Benchmark: 43.78393.)

cp_si - si-vbc-lda-3.in: **FAILED**.
t1
    ERROR: absolute error 3.69e-01 greater than 1.00e-05. (Test: 2527.82355.  Benchmark: 2528.19283.)

All done. ERROR: only 10 out of 17 tests passed.

Is it something expected or should I worry?
In the second case, do you have some ideas how to correct it?

Best regards
