Despite its popularity and impact, I-O psychologists have largely neglected Lean as a research topic and few I-O psychologists engage in applied practice in the area.  ...  In this focal article, we provide a working definition of Lean and present examples of Lean's influence. Next, we outline possible reasons to explain I-O psychologists' indifference to Lean.  ...  Climate and culture I-O psychologists have a long history of researching the influence of organizational culture and climate on employee performance, attitudes, and well-being.  ...

Experimental results on NERSC's Hopper indicate that our approach effectively isolates I/O variation on shared systems and improves overall I/O performance significantly.  ...  As the number of compute cores on modern parallel machines increases to more than hundreds of thousands, scalable and consistent I/O performance is becoming hard to obtain due to fluctuating file system  ...  There have been many optimizations to improve collective I/O performance [7] , [33] , [15] , [31] , [22] , [26] , [23] , [21] , but even with these improvements, collective I/O operations in large-scale  ...
