Please write a description in this text box of the changes that are being\r\n   made.\r\n\r\n1. Please ensure that you have written units tests for the changes made/features\r\n   added.\r\n\r\n2. If you are closing an issue please use one of the automatic closing words as\r\n   noted here: https://help.github.com/articles/closing-issues-using-keywords/\r\n\r\n3. If your pull request is not ready for review but you want to make use of the\r\n   continuous integration testing facilities please label it with `[WIP]` and\r\n   then remove the label when you'd like it to be reviewed.\r\n\r\n4. Once review has taken place please do not add features or make changes out of\r\n   the scope of those requested by the reviewer (doing this just add delays as\r\n   already reviewed code ends up having to be re-reviewed/it is hard to tell\r\n   what is new etc!). Further, please do not rebase your branch on master/force\r\n   push/rewrite history, doing any of these causes the context of any comments\r\n   made by reviewers to be lost. If conflicts occur against master they should\r\n   be resolved by merging master into the branch used for making the pull\r\n   request.\r\n\r\nMany thanks in advance for your cooperation!\r\n\r\n-->\r\nThanks, Stuart, it really helped me to refresh my memories and understand what the arguments are and how to use them. I've implemented simple TBB parallel for version for it. It does not use NUM_THREADS argument, instead it allows TBB's algorithms to define the number of tasks itself while iterating by dimension[0] range. As result, peak performance on the BlackScholes (middle sizes) raises even higher.. but it is still not enough and I'll keep working on OpenMP version and better TBB performance tricks.","created_at":"2018-08-04T02:34:22Z","updated_at":"2018-08-04T02:34:22Z","closed_at":null,"merged_at":null,"merge_commit_sha":null,"assignee":null,"assignees":[],"requested_reviewers":[],"requested_teams":[],"labels":[],"milestone":null,"commits_url":"https://api.github.com/repos/stuartarchibald/numba/pulls/1/commits","review_comments_url":"https://api.github.com/repos/stuartarchibald/numba/pulls/1/comments","review_comment_url":"https://api.github.com/repos/stuartarchibald/numba/pulls/comments{/number}","comments_url":"https://api.github.com/repos/stuartarchibald/numba/issues/1/comments","statuses_url":"https://api.github.com/repos/stuartarchibald/numba/statuses/575962557f6b681460d31d0d736bb901c94c2cb9","head":{"label":"anton-malakhov:develop","ref":"develop","sha":"575962557f6b681460d31d0d736bb901c94c2cb9","user":{"login":"anton-malakhov","id":7475946,"node_id":"MDQ6VXNlcjc0NzU5NDY=","avatar_url":"https://avatars2.githubusercontent.com/u/7475946?v=4","gravatar_id":"","url":"https://api.github.com/users/anton-malakhov","html_url":"https://github.com/anton-malakhov","followers_url":"https://api.github.com/users/anton-malakhov/followers","following_url":"https://api.github.com/users/anton-malakhov/following{/other_user}","gists_url":"https://api.github.com/users/anton-malakhov/gists{/gist_id}","starred_url":"https://api.github.com/users/anton-malakhov/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/anton-malakhov/subscriptions","organizations_url":"https://api.github.com/users/anton-malakhov/orgs","repos_url":"https://api.github.com/users/anton-malakhov/repos","events_url":"https://api.github.com/users/anton-malakhov/events{/privacy}","received_events_url":"https://api.github.com/users/anton-malakhov/received_events","type":"User","site_admin":false},"repo":{"id":71483245,"node_id":"MDEwOlJlcG9zaXRvcnk3MTQ4MzI0NQ==","name":"numba","full_name":"anton-malakhov/numba","owner":{"login":"anton-malakhov","id":7475946,"node_id":"MDQ6VXNlcjc0NzU5NDY=","avatar_url":"https://avatars2.githubusercontent.com/u/7475946?v=4","gravatar_id":"","url":"https://api.github.com/users/anton-malakhov","html_url":"https://github.com/anton-malakhov","followers_url":"https://api.github.com/users/anton-malakhov/followers","following_url":"https://api.github.com/users/anton-malakhov/following{/other_user}","gists_url":"https://api.github.com/users/anton-malakhov/gists{/gist_id}","starred_url":"https://api.github.com/users/anton-malakhov/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/anton-malakhov/subscriptions","organizations_url":"https://api.github.com/users/anton-malakhov/orgs","repos_url":"https://api.github.com/users/anton-malakhov/repos","events_url":"https://api.github.com/users/anton-malakhov/events{/privacy}","received_events_url":"https://api.github.com/users/anton-malakhov/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/anton-malakhov/numba","description":"NumPy
