Dear all,

I want to do the BSE calculation(I performed a runlevel of "yambo -b -o -b -y d":, But I am getting the error:
"Operating system error: Cannot allocate memory Out of memory''.
I post the report file of my BSE calculation.

Dear Mojitaba,
probably the dimension of your excitonic matrix (86016) is too big for a direct diagonalizataion.
I suggest you to use the Haydock iterative method (-y h) instead of (-y d).

Best,

Daniele
