cluster computing - qsub array job - get number of tasks -

-
is possible number of tasks submitted array job? $sge_task_id task number. for example if submit job qsub -t 1-4 my_script.sh i'd 4 . i don't know of automatic variable that, can think of way via torque (i'm betting same arguments work sge or have corresponding arguments). unfortunately, you'd have manually: qsub -t 1-4 my_script.sh -v total_tasks=4 then, within job script you'll have environment variable $total_tasks set desired. doesn't give automatically give information need.

Why does git-describe prefix the commit ID with the letter 'g'? -

-
typical output of git-describe looks like some-tag-32-gf31f980 where some-tag tag name, 32 means described commit 32 commits after commit tag, , gf31f980 means commit id uniquely abbreviated f31f980 . my question g in gf31f980 . why there? first thought inserted disambiguate parsing of output of git-describe . can't think of case in helps have it. example, 32 component might omitted, , there no way know output above describes commit 32 commits after tag some-tag , rather commit at tag some-tag-32 . g doesn't this. a regex match extract commit id can search /-g([0-9a-f]+)$/ . there no easy way simplify this; can't /-g(.*)$/ example because might erroneously match g in tag name. without g still /-([0-9a-f]+)$/ , g isn't helping there. non-regex parsing processes behave similarly. the g generated explicitly; relevant source code (around line 240 of builtin/describe.c ) is: static void show_suffix(int depth, const unsigned char *sha1) { ...

i have pandas dataframe: df=pd.dataframe({'a':[1,1,2,2,3,3],'b':['c','t','k','c','c','k']}) i need group df , remove groups b ='t'. pandas groupby syntax this? in example answer groups 2 , 3. a groupby/filter work here (filter return groups meet condition). so, example, following: >>> df.groupby('a').filter(lambda x: (x['b'] != 't').all()) b 2 2 k 3 2 c 4 3 c 5 3 k (x['b'] != 't').all() allows keep group if there no rows 't' in column b or write filter following way: create booleen series based on whether row of column b 't'. if sum booleen series, sum greater 0 if of elements 't': >>> df.groupby('a').filter(lambda x: (x['b'] == 't').sum() == 0) b 2 2 k 3 2 c 4 3 c 5 3 k there other ways write filter condition have same flavor.
