hpl on ubuntu 18.04

HPL(High Performance LINPACK) 을 한번 돌려봄.

특이하게(?)도 openMPI를 통해서만 구동이 되고, 단독으로 실행시 아래의 에러가 발생한다.

$  ../xhpl 
HPL ERROR from process # 0, on line 419 of function HPL_pdinfo:
>>> Need at least 4 processes for these tests <<<

HPL ERROR from process # 0, on line 621 of function HPL_pdinfo:
