i in fortunate position of having access university's slurm powered gpu cluster. have been trying tensorflow run in cluster node, far have failed find documentation. (everyone have spoken @ university has run using cpu nodes before or using single gpu node. i found excellent bit of documentation previous question here . unfortunately, it's rather incomplete. of other distributed examples have found such such this 1 rely on explicitly specifying parameter server. when try run using code question, appears work until either fails connect nonexistent parameter server or hangs when server.join called , no print outs provided sbatch outfile (which understand should happen). so in short, question how 1 go starting tensorflow on slurm cluster? sbatch stage onwards. first time dealing distributed computing framework besides spark on aws , love learn more how configure tensorflow. how specify 1 of items in tf_hostlist example server parameter server? alternatively can use sbat...

this question has answer here: what comma in javascript expressions? 4 answers so on site , peeking source code, , javascript code obfuscated(as usual). don't know obfuscated code normally, think this: var1 > 10 / 2, var1 = 0 is same as if(var1 > 10 / 2){ var1 = 0; } is how is? if not, please tell. you can see happen, when place code inside of parenthesis inside of console.log. need parenthesis, because console.log reads comma separator parameter. comma operator : the comma operator evaluates each of operands (from left right) and returns value of last operand. var var1; console.log(var1); // undefined console.log((var1 > 10 / 2, var1 = 0)); // 0 console.log(var1); // 0
