QR_factorizatio

Postby zcz1005 » Fri Mar 30, 2018 5:12 pm

HI,

I used c interface of scalapack (pdgeqrf_) for QR factorization.

But, when the size of my matrix is small (compared to block_size), then the code would spill "BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES". As long as I increase the size of matrix, everything goes well.

Despite the termination of code, the result obtained is still correct.

anyone knows why, comments?

Thanks
